Ah, yes, NSAs, LGS, another NSA.
Can you figure out that one, Chris? :wink:

BTW :facepalm: , neptunium, if you can figure out LGS, you might be able to do NSA, too.

That's a non-standard acronym use there. I'm afraid I'm going to have to issue a citation.

You don't seem sincere enough in your contrition. More grovelling!

35000 Meters per Second = 78,292 Miles per Hour?
1 Meter per Second = 2.2369 Miles per Hour?
The speed of Geminid meteoroids above the atmosphere (Vinf) is 35 km/s. So when you see them burning up, air resistance has slowed (and is continuing to slow) them down. But just a little.

FWIW, Geminids are one of the slowest showers, and definitely the slowest major shower. That's part of what makes these meteors so impressive.

Nice Work!! I just noticed that Iran is at about the same latitude as where I live in Florida ~~ the stars are in the same position as I see them here.

Neat! 8-) I liked today's selection with Orion in the center and Sirius to the left with the meteor in between. 8-)

Image A Geminid Meteor Over Iran

Explanation: Some beautiful things begin as grains of sand. Locked in an oyster, a granule grows into an iridescent pearl, lustrous and lovely to behold. While hurtling through the atmosphere at 35 kilometers per second, a generous cosmic sand grain becomes an awe-inspiring meteor, its transient beauty displayed for any who care to watch. This years Geminid meteor shower peaked last week with sky enthusiasts counting as many as 150 meteors per hour, despite the din of bright moon. Pictured above the Taftan volcano in southeast Iran, a meteor streaks between the bright star Sirius on the far left and the familiar constellation of Orion toward the image center. Sky watchers are looking forward to next years Geminids which should peak during a unobstructive new Moon.
