(meteorobs) June Bootids from Oregon, morning of 6/23

[Wesley Stone]

I didn't get out for the first part of the night, as thunderstorm clouds were still abating and I needed to get some rest.  The sky was pretty nice when I got out at around 2 am.  I watched for a bit over 2 hours into morning twilight, hoping that this would give me the best chance to see some June Bootids.  There was some activity, but it was somewhat underwhelming against a strong sporadic background.  In 2.1 hours Teff, I counted 54 meteors, 13 of which fit the radiant alignment and velocity parameters for June Bootids.  None of my JBOs were brighter than magnitude 1.  Aside from slowness (but there were a lot of slow or medium-slow sporadics, especially in the first hour), the outstanding characteristics were an abundance of wakes or short trains (6 of 13 JBOs, 6 of 41 other meteors) and orangish or reddish color (4 of 13 JBOs, 2 of 41 other meteors).
