Dec 14/15 Meteors (night after the Geminids peak)
December 16, 2010 1 Comment
What a difference 24 hours makes! Only a day removed from the Geminids peak and rates have crashed to a fraction of their peak. During the past 5 nights SALSA3 detected 12, 22, 69, 124 and now 20 Geminids. This is a characteristic of the Geminids in that the post-peak rates fall off much more rapidly than the pre-peak increase.
The night of Dec 14/15 marked the 81st consecutive nights that SALSA3 detected a meteor. As of right now, there is a good chance that it is clear enough for night 82 to produce a few meteors. Tomorrow night will be iffy as a storm, our first in 2 months, is forecast to bring rain and clouds to the area. Will the streak survive? We’ll have to wait and see.
