Lovejoy the Tail Wagging Comet

Morning readers.  Thanks for coming by.  The traffic’s down on the blog so far I figure I can talk about Lovejoy a bit more without boring too many people back to sleep.  First, here’s what’s on Spaceweather dot com about it this morning:

THE AMAZING TAIL OF COMET LOVEJOY: Widespread reports of Comet Lovejoy‘s tail are being received from around the southern hemisphere. The ghostly plume emerges just before sunrise, jutting vertically upward into the eastern sky ahead of the sun.

“I observed the comet with my unaided eye for 55 minutes this morning,” says Colin Legg of Mandurah, Western Australia. “I also captured a timelapse sequence of the comet rising as twilight progressed.” Click on the image at the site to set the scene in motion.

“In the image you can see 2 tails,” notes Clegg. These are the dust and ion tails. The gaseous ion tail is blow almost directly away from the sun by the solar wind, while the heavier, brighter dust tail more closely follows the comet’s orbit.

The visibility of both tails could improve in the days ahead as the comet moves away from the sun and the background sky darkens accordingly. Early-rising sky watchers should be alert for this rare apparition. [finder chart]

Edit 8:00AM:  I decided to try to embed that video by Colin Legg here so’s I can watch it without trying to remember how to get back to the site:

 

Comet Lovejoy (2011 W3) rising over Western Australia from Colin Legg on Vimeo.

Over the next while I’m figuring to attempt to duplicate the behavior of that tail inside a fish bowl full of circulating water orbiting a tube of permanent magnets stacked atop one another, then electromagnets if the permanent ones don’t do the trick.  I’ll have an anode on one side of the fishbowl, a cathode on the other injecting, first colloidal iron, then if necessary, other metals into the circulating water.

I’m harboring a lot of curiosity about what that tail’s saying.

But for those of you who don’t click the spaceweather site I’ll give you this thing some guy did with a pinhole camera and a beercan showing the anelemma of the sun over several months:

THE SUN IN A BEER CAN: I have captured the sun in an empty beer can,” reports Jan Koeman of Kloetinge, the Netherlands. In June 2011, Koeman assembled a solargraph–a simple pinhole camera consisting of a beer can lined with photographic paper–and for the past six months he has used it to record the sun’s daily motion across the Dutch sky. Today he removed the photo-paper for inspection. 

“This is what a photo with an exposure time of nearly 6 months looks like,” says Koeman. The highest arcs were traced by the summer sun of June 2011. The lowest arc was made just today, Dec. 21st, on the eve of the 2011 winter solstice. Occasional gaps are caused by clouds.

Curiously, Koeman had more than one empty beer can to work with on that hot summer day in June when he began his project, so there are multiple views to enjoy. Click here for more solargraphs.

Got me thinking maybe all that weirdness we’ve been seeing across the face of Old Sol lately might be the result of a combination of a hangover and spending several months jail-time inside a beer can.

Sundragons and Other Serious Stuff

Good morning readers.  I’m gratified you came by for a read.  There’s a lot going on in the Universe this morning, but most of it is too big, or too little to get a gander at, so I’m going to give you an opportunity to shrug it all off as I’m doing.

If you’re the sort of person who sees herds of cattle, naked women, elephants, alligators and stagecoaches in clouds, mountains and whatnot you’ll see immediately what was on Old Sol’s mind yesterday:

Which doesn’t require any further discussion except to say:

Which also speaks for itself.  Enough said about that.

 

Unless you want to hear it in song.

But if you’re feeling more in the serious and unsmiling turn-of-mind this morning you probably won’t grasp the implications and ramifications of that.

Instead you’d probably prefer something you can’t shrug off.  For you, I suggest you have a look at the comet Lovejoy as it passed away from the sun:

http://spaceweather.com/archive.php?view=1&day=19&month=12&year=2011

http://spaceweather.com/images2011/18dec11/spiraltail_strip.jpg

All that wiggling and wagging it’s doing with the tail might be the most interesting thing human beings have had an opportunity to view since the invention of the camera, the rocketship, the atom and other genius gadgetry of modern life including toasters.

Lovejoy is telling you something it might take human beings a longish time to hear, if they ever get around to hearing it at all.  Which seems about equally likely.

With the possible exception of the cats, chickens, and the occasional folks out there who see it but ain’t about to say anything.

But I’m not going to say any of that.  Instead, I’ll just say I’m figuring I might post something later along more interesting lines.

Thanks for coming by.

Mysterious “white web” found growing on nuclear waste

I’ll leave it to you to decide what’s strange about it. Cob-webs around here are the norm. Maybe it has something to do with the nuclear waste part of things. Old Jules

Got A Holiday Greeting From The Time Department

Hawaii Konate, the people who keep me posted on what time it wasn’t over the past while, what time they think it probably isn’t now, and what time they’re middling sure it won’t be in the future sent me a nice greeting by email.

The card arrived in my hotmail email box at 3:25 AM someone’s time, maybe mine, maybe theirs, maybe hotmail’s.   I’m not sure whether that picture is of something at the Hawaii site, or whether it’s wherever they speak the language at the top of the circular they send out:  BUREAU INTERNATIONAL DES POIDS ET MESURES, ORGANISATION INTERGOUVERNEMENTALE DE LA CONVENTION DU METRE. [Muddy muddy muddy etcetera]

But even if I knew what time it wasn’t in that city where the place on the card isn’t, I still wouldn’t know what that thing is they sent me a picture of wishing me a Merry Christmas.

I generally don’t like people telling me what kind of Christmas to have, but especially I don’t like them telling me how to have a whole year.    But in this instance, they did let themselves be nailed down on the thorny issue 0f 2012.  2012, unless they’re being cunningly sarcastic, isn’t a time that won’t happen.

The card didn’t come with one of the circulars they send out telling what time it hasn’t been all over the place, what time they don’t think it is now, and what time they don’t think it will be in the future.  That would be unsettling if they hadn’t gone ahead and mentioned 2012 in the card.

So maybe there was no authoritarian motive behind telling me what kinds of Christmas and 2012 to have.  Maybe they were being subtly reassuring.

I suppose it’s probably best not to try to second-guess them.

I’d Sure Like to Have Me One of Them Drones

Morning readers.  I’m obliged you came by for a read.

I’ve been studying on that picture of the pretty little airplane those whatchallit, Iraning people found in the sky and captured.  I’m fairly impressed and would sure like to have me one, even though I haven’t figured out exactly how it works.

 

That airplane doesn’t have much in the way of control surfaces and weight-and-balance might be tricky.  Not as much rudder on it as a person might wish.

I’m wondering if a person might lure one down with an orange jump suit, Helicopters and Orange Jump Suits.  If those things are flying around some silly-assed place like whatchallit, Irang, where there’s nothing to see but a bunch of Persians, seems to me they’re bound to be flying around here where there’s really good stuff.

Anyway, they can’t be that hard to catch.  A man with a CB radio might be able to snag one, I’m thinking, if the orange jump suit didn’t do the trick.

I’ll have to study on it after I’ve got it to decide whether it’s best to put a harness underneath of the hang-glider variety, or mount a saddle on top.  I don’t like the idea of riding it bareback the way Slim Pickens rode that bomb.  Until a person got the feel for it, that thing might just buck some.

Besides, I’m used to more rudder than that and I’ve never flown anything without a tail section.  Likely I’d want to fly it around treetop level a while so I didn’t have too far to fall at first.

If I’m good maybe old Santy will bring me one.

Muddy muddy muddy etcetera

You’ll be happy to know Old Sol’s finally getting things under control up there.

 
That line of misbehaving sunspots that were marching across above the equator so long finally got its comeuppance.  Today there are only three honest-to-goodness ones and the litter of little peckerwoods just coming around the horizon. 
 
Astrophysicists aren’t in agreement about what was getting out of hand up there, but many now assert it might be mud and all this rain that finally got it under control.  There’s been so much rain lately every stick of firewood here’s been soaked, and even though cooling down Old Sol with wet firewood would be a big job of work, eventually it was bound to happen.  Probably the reason for this cold snap, too.
 
But the other line of thinking among Hopi Elders, surviving Mayan track-of-time keepers, and the folks at BUREAU INTERNATIONAL DES POIDS ET MESURES, ORGANISATION INTERGOUVERNEMENTALE DE LA CONVENTION DU METRE, believe there’s a more novel reason that line of sunspots dwindled.  They couldn’t stay in step. 
 
Time, they assert, is so screwed up it’s impossible to keep anything going with any regularity and the sunspots finally just got too frustrated to keep trying.
 
There might be a lot to that.  I get the email reports from the Hawaii Konate folk, and the circular always starts off with the caveat:
 
“Coordinated Universal Time UTC and its local realizations UTC(k). Computed values of [UTC-UTC(k)]   and uncertainties valid for the period of this Circular. From 2009 January 1, 0h UTC, TAI-UTC = 34 s.”
 
Those uncertainties cover a lot of ground all over the planet and the people making a living trying to keep track of what time it is send out the Circular to advise interested parties of what time it wasn’t, mostly, any given day in cities of clockwatchers.  But even telling what time it wasn’t has a considerable uncertainty factor, which they aren’t ashamed to admit.
 
I don’t know why they even keep those people on the payroll if they can’t tell us what time it wasn’t.
 
I’m going to kick this around with the cats and chickens.  See if we can’t figure out a way to get a piece of the action on this timekeeping racket.

Simultaneity of Events – Needing some ideas

Some of you readers are a lot smarter than I am, and I happen to be stuck.  I’d be obliged if any of you can wrap your minds around this problem and tell me how to do it. 

One of the projects I work on daily involves series regularly scheduled ‘events’ happening across the world.  Every day they’re conducted at the same locations and at repeated intervals, several hundred times each day for each location. 

I know the precise geographic coordinates for the locations and the local times of the events.  But one part of the experiment requires examination and comparisons of simultanious events, say, from a location in Australia, another in NY, another in Rhode Island, to keep it simple.

But two events happening, say, in Rhode Island and New York at the ‘same time’ by the clock are actually several minutes apart.  They occupy the same time zone, but events in Rhode Island at 3PM aren’t the same events as those happening in NY at 3PM. 

But even without taking DST into the equation, events in Australia might be 15 hours and 30 minutes later by the clock to be simultaneous with New York, or Rhode Island, and only one of the two.  The event in one would be simultaneous with Australia several minutes earlier, or later, than the other.

I can calculate minute-by-minute sidereal times for each of the locations, but establishing a baseline for the relationships in terms of simulataneity eludes me.  I do all this on a spreadsheet.  I know nothing about programming computers.

I’d welcome any suggestions.  Particularly if it involves something automatic and repeatable.  It’s probably something simple, even stupid, but I’d like to get past trying to figure out how to do it and get around to actually doing it.

Gracias, Old Jules

I’ve got to get going.  I’ll be back online sometime later today.

WordPress is behaving as though it gets paid by the hour this morning.  Everything’s taking forever to load.  Besides, the blog never gets much traffic Fridays anyway.  So I’m going to try the patience of those of you who do visit by indulging in a post I promised my friend Rich in North Carolina and a couple of others I’d put up.  

I’ve got a goodly bit on the plate elsewhere today and mightn’t be around the cabin much, but if WordPress goes on salary and I’m back I might put something else up later.

Some of you expressed an interest.

Blind Chickens, Talking Diamonds and Greedy Galaxies

I’m aware some of you readers keep chickens.  If you’re having problems with blindness among them you might be interested in joining http://tech.groups.yahoo.com/group/Free_Ranging_Chickens/ where there’s an interesting discussion going on about the problem.  This was the beginning post for the thread:

Blind Rooster
Posted: Sat Dec 3, 2011 5:47 am (PST)
Just wondering if anyone has had any experience with this. Monday afternoon, I noticed two hens on the wrong side of the fence, so went to retrieve them, and find the rest of their little band. Found all but one rooster. Couldn’t find him in any of the “regular” places, but they do have lots of room to roam. Figured I’d check again before bedtime, as he’s usually the first one in. Didn’t show up. Put everyone else in, and went hunting, for feathers if nothing else:(. Well, I found him by the fence, but inside. Just sitting there. He let me pick him up without protest, but he’s always been laid-back. Still, I knew something was wrong. Put him in a different coop, with shelves instead of bar roosts. The next day he was down on the floor, walking around, but bumping into the screening for the duck section, and sitting in corners/nests. Realized his vision was at least partially gone. Blocked him in, and started antibiotics, since I had no idea what else to do. That night he was back up on the shelf, so he must have some vision, I guess. Wasn’t eating or drinking that I could see, just walked over everything. Brought him into the Hospital Unit (a carrier in my bathrooom :). He began to drink, and finally eat. He crows (oh, swell) but his cue seems to be noise rather than light. Put him outside yesterday (in a big crate) afternoon for some sun, but he just sat there. Some of the other chickens did come scratch around him, but he seemed oblivious.
His eyes look odd, not whiteish, but the center (behind the cornea and inside the iris, where it should be black) looks “solid”, if that makes any sense.

Any thoughts?

In the quantum world, diamonds can communicate with each other

December 2, 2011 By Joel N. Shurkin

The vibrational states of two spatially separated, millimeter-sized diamonds are entangled at room temperature by scattering a pair of strong pump pulses (green). The generated motional entanglement is verified by observing nonclassical correlations in the inelastically scattered light.

Elsewhere in the news, the 99% movement has suffered a disturbing setback with the discovery we live in a greedy galaxy, gobbling up smaller galaxies.  http://www.physorg.com/news/2011-11-beast-tails.html

The Milky Way galaxy continues to devour its small neighbouring dwarf galaxies and the evidence is spread out across the sky.

Government and Wall Street Cray computers working on the problem tentatively estimate the 99 percenters are actually 0.000000000000001 percenters galaxy-wide.  Political and financial-industry hired-guns are working three shifts to prepare television documentaries and PR campaigns to assist in correcting the error.

In a related story, multi-national corporations and Wall Street banks have hired a team of astrophysicists and astronomers to study black holes in an effort to develop more thorough strategies and techniques to solidify and expand their holdings.  Additionally, the illustration on the right suggests black holes might also provide improved methods in the use of pepper-spray.

(Right) An artist’s conception of the black hole system, showing the black hole drawing material towards it from a massive, blue companion star. This material forms a disk and jets that emit radiation. Credit: Optical: DSS; Illustration: NASA/CXC/M.Weiss

“Black holes are among the most amazing and bizarre predictions of Einstein’s theory of gravity. A black hole is thought to be point-like in dimension, but it is surrounded by an imaginary surface, or “edge,” of finite size (its “event horizon”) within which anything that ventures becomes lost forever to the rest of the universe.”  http://www.physorg.com/news/2011-11-black-hole-unmasked.html

The overall optimism derived from these stories was something I wanted to share with you readers to lift whatever waning spirits you might experiencing his crisp, rainy morning.

Old Sol’s Party-Animal Mood Swings Bring Mixed-Reactions

ERUPTING FILAMENT: Today, with little warning, a magnetic filament rapidly erupted on the sun. Between 10:30 and 11:30 UT, observers in Europe watched tendrils of hot plasma rocket away from the sun’s NW limb. Debris from the explosion is not expected to hit Earth. Images: #1, #2, #3.

Astrophysicists aren’t certain what he was shooting at, but several noted deer season recently opened.  Others speculate Alpha Centauri was throwing bottles or tin-cans in the air for him.

With no flares of significance in days, the sun is strangely quiet. Nevertheless, the view remains dynamic. Rogerio Marcon of Campinas, Brasil, took this picture of the local starscape on Dec. 2nd.   Using a telescope tuned to the red glow of solar hydrogen, Marco captured 20 billion sq. km of seething plasma and magnetic filaments; also included in the field is the dark core of sunspot 1364 (lower right). It doesn’t look very quiet. NOAA forecasters estimate a 30% chance of M-class solar flares in the next 24 hours.  http://spaceweather.com/

Some astrophysicists noted 20 billion sq. km of seething plasma and magnetic filaments could be considered a middling lot, everything else being equal.

PHD candidates from UC Berkeley and MIT have gone on record with a theory there’s some kind of celebration going on up there.  NASA space cadets believe otherwise, but refuse to elaborate except to darkly hint Old Sol’s expressing his displeasure about agency budget cuts.

Israel and the CIA aren’t saying what’s causing it, but are planning airstrikes on unnamed Central Asian targets in retaliation.
