REMARKS:
1. Meteors I was unsure about because they generally lined up in the
vicinity
of Mars are listed as SPOs. I hope that's acceptable.
2. Meteors # 6, 8 & 16 looked like Perseids to me but I wasn't sure
if I should report them as such since that radiant was upside down in my
FOV.
3. Meteor #17 went from West to East but I couldn't find any notes on those
weird
radiants for this month. Any help would be appreciated with that.
4. I saw a few nice ones as I was getting settled in to begin but I hadn't
acquired ZLMs
yet and my eyes weren't fully adapted to the night yet.
Should I have recorded them regardless of those two factors?
5. Should I average out the LMs from the intervals or just report them
individually?
Any help with these 5 lame questions would be most appreciated.
Clear skies,
-SID!
