(meteorobs) IMO-NEWS: Giacobinids returned! (Japan)




Sure enough, a few minutes behind Gary Kronk's post, along came this
report over the official "imo-news" list! It seems this observing group
was fortunate enough to see at least some unusual Draconid activity...
Note that the actual number of meteors seen was quite small, but with
(IMO-style?) corrections, the theoretical "ZHR" was *much* higher!

BTW, was this the Japanese group you meant, Gary - was there another?

Clear skies,
Lew Gramer

Giacobinids are rich in faint meteors.  Sky conditions and perception
coefficient of observers affect heavily on ZHR estimates.  Bright Moon
hindered observations and SD are rather large.
