Hello!
I observed the skies for two hours around the predicted Ursid peak from my
Bortle class 5 backyard to check for any enhanced activity. The sky was quite
transparent with a very strong northeasterly wind gusting up to 100 km/h. A
spectacularly strong gust nearly knocked me over in my observing chair! My LM
hovered around 6.0, low compared to the usual ~6.5 during similar conditions
(strong northeasterly wind, dry air). Setting up my equipment, I saw a -1.
magnitude Ursid at 18:01 UT. Encouraged by this, I started my watch at 19:10.
It didn't take much to see several more bright Ursids. The first hour ended
with 8 Ursids seen. This rate persisted during the second hour, with 9 Ursids
seen, including a spectacular -3. magnitude 50-degrees long yellow-orange
meteor with three blue bursts and a 4-second persistent train! Looking at
Michel's report, our rates are very similar and it appears that the activity
was lower before and after my watch. I ended my observation at 20:15 UT,
because of the brutal conditions.
