Two Big Events in One Day!

Wow.  I must be living right.

First, at the Hospice Thrift Store in Kerrville I found these gloves with no fingertips for $1.50.  When it’s cold in this cabin I go to 18 layers of longjohns and sweatsuits, Sorel snowboots and innovative headgear.  But my fingers stiffen until I can only use the computer with a lot of mistakes.

I’m thinking those gloves are going to fix that one.

But on arriving back home and tuning the computer to this frequency I found to my delight that Michael had explained the solution to another one I’ve been scratching my head over longer than I care to admit.

Thank you Michael.

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.

Thanks for coming by for a read.

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.

 

Then there’s this:

Then there’s this:
