(meteorobs) Positive sighting Xi Bootids!



About 2 hours after my spectacular (probable) -16 fireball experience,
the skies cleared and I attempted a search for XBO activity. (Maybe,
subconciously, I hoped for another -16? ). 

I definitely saw 2 XBO in 1hr Teff. In fact they came just seconds
apart, far from the radiant. One had a trajectory that could be either
XBO or VIR, but its speed matched the other XBO, too fast for VIR.

Overall a good mix of other activity too, namely 2 VIR a DVE and a
bright ACE (most likely vs TCE).

Conditions good, but I got very sleepy, and wanting to conserve energy
for more Teff tomorrow night, better hit the sack.

Too much excitement for meteor "low season" , I guess!

Mike.

P.S. I hope this near realtime report (and Kim's) will encourage Far
East observers to watch for the now definite XBO activity.

DEAD TIME: 2 min

Note1: Two Xi Bootids observed a few seconds apart. The first one
trajectory could not be differentiated XBO/VIR, but it had identical
medium-fast velocity as the 2nd one which had trajectory unambiguously
XBO.

Note2: The ACE had trajectory indistinguishable from TCE, but the
path length/TCE radiant ratio was too large. So ACE is most likely
source, even though that radiant just slightly below horizon at 1:46am
local time.
