(meteorobs) Star Party and early watch for Coma Berenicids
Hello list,
Last night was our monthly Hawaiian Astronomical Society star
party at the Dillingham site on Oahu's north shore. As is typical for
the fickle weather out here at sea level, it was clear and sunny in
town, but overcast and rainy at the observing site! To make matters
worse, we had a few busloads of students who came out to
observe through all the big scopes - what a drag. Surely enough,
after the last busload left in disgust, it cleared up enough to do
some observing! So the remaining diehards got to see some nice
sights under LM=6.3 The seeing was good. I saw an occultation of
a Jovian satellite through a 18" Dob. Jupiter is at the Zenith here
this time of year, and the surface details like the red spot and the
knots in the bands are really sharp and clear. Several Sporadic and
Anthelion meteors were seen.
Early in the evening, around 7:15pm many people saw a bright
flashing in the sky above the solid cloud layer. It reminded me of
the mega-fireball I saw last year and this may have been another
smaller one, maybe around mag -10 or so?
Star parties being just that, I couldnt find an hour free time alone to
do meteorobs, so on the drive back home I saw a nice clear
opening in the clouds and observed for an hour near Mililani town. I
saw no action from the proposed Coma Berenicids radiant at 12:32
+22° My conditions were pretty good at LM=5.8 with the radiant at
38°, so I should have seen something if it existed, but only saw 2
Anthelions, 1 Gamma Velid and 5 SPO. Of course its still 3 days
before the expected peak. But, worth a try anyway. Will try a more
detailed session Tuesday night during the "peak".
Good Observing to all!
Mike.
