Two mistakes here(?)
a. LM 4.3 or 4.9? (Dustin replies: 4.3 is correct)
b. 1 Leonid or 2 Perseids? (Dustin replies: one Leonid at mag 1)and(No Perseids in November - oops :-)
Following your detailed data below, it seemed that you saw one Leonid with
1st mag.? But i'm puzzled what's *MAG (1-5)* mean. It looks like for
velocity estimate instead of brightness. Why the apparent magnitude of
meteors can be limited within the range 1st to 5th mag.?
:-)
(Dustin replies: yes one Leonid with mag 1. MAG (1-5) the (1-5) meant nothing, it is a leftover from my botched cut and paste job, sorry, see resubmission above.
Kind regards,
Huan
