I drug my kids out of bed at 0300 MST to give them a last chance to see a
meteor storm. We finally got situated about 0315, lying in the back yard with
an improvised moon shade. I divided the time we were out into segments to try
to identify a peak. The data is below:
Time #1 #2 #3 #4
-------- ----- ----- ----- -----
0315-0330 5 11 12 19
0330-0345 26 44 49 56
0345-0355 28 41 52 44
0355-0405 13 Zzzz 13 25
0405-0415 14 Zzzz 9 11
----- ----- ----- -----
Total 81 85 123 136
Notes:
1. Observer #1 (me) didn't start with the others and had the smallest segment
of visible sky.
2. Observer #4 had the widest segment of sky.
3. Observer #2 decided to count meteors on the inside of his eyelids for the
last two periods.
4. The time periods are not the same size. It appears that our peak was
between 0345 and 0355 MST. I wish I had done ten minute breaks from the
beginning.
I guesstimated the limiting magnitude (for my old eyes) at about 4. Using the
nomogram in the November Sky & Tel, it would indicate that we would see about
5% of the local ZHR. That would place the ZHR at about 3360 for our location,
during the peak period.
I didn't see any of the 30-40 degree, huge fire balls that we saw last year
from the same location (observing through clouds.) Most of the ones we saw
were short, relatively dim. I did see the second fireball that Steve Coe
mentioned. I wasn't watching when he saw the first.
Comparing with the other observers' reports, it appears that Peoria was the
place to be for Arizona Leonid observing.
Clear skies.
