Default The sky was full of meteors!

The Geminids put on a very impressive performance over Colorado this
year. Last night my video allsky camera recorded 298 meteors, of which
at least 232 were Geminids. It caught a total of 419 Geminids over the
last four nights. Although the camera is only sensitive to magnitude 1,
it recorded a peak rate of 50 meteors per hour at 4am local this morning
(UT 11:00 14 December). I went out a few times during the night and
always saw many events, typically two or three per minute.

I've posted a composite image and many fireball videos at

That's way better than anything our NASA has to offer.

Yes, no question !

I only saw 12 from 5:18 - 5:56 am EST
But then I'm under mag 4.0 skies at best, with
massive lighting 300m away in the park. (tho was
able to shield myself from them somewhat)

The brightest emanated from Castor's foot to
almost the ground, very bright. One went from
N to S just west of Mars.

All the rest emanated from the Leo area, and streaked
ESE above Corvus and Crater, with one exception
which sailed right past Saturn heading east.

Thanx Chris.

This must be an error. No reports show anything even remotely close to the
number of ones you recorded. Are you sure you're not confusing data with a
prior shower?

No chance of such confusion. A peak rate of 50 meteors per hour brighter
than magnitude 1 (which is what I recorded) is reasonably consistent
with a peak visual rate of 150 meteors per hour (which is what the IMO
reported).

The composite I posted has an interesting featu Pollux is just bright
enough to show a faint trail. Since it is only a few degrees from the
Geminid radiant, you can use its position on the image to tell
approximately when any individual meteor occurred. You just need to
follow the path of a meteor backwards until it intersects the trail of
Pollux. If the intersection is towards the east the meteor was early in
the evening; towards the west it was approaching dawn.

Carl, Chris's numbers are consistent with radio meteor observing,
although radio observing sees fainter.

Cool, I'll give it a try.

You don't have a larger sized ver of that image ?
