2010 六月牧夫流星雨 牛人们的观测报告

Hi, Paul and others,

Many thanks for these reports. They are very important due to the lack
of other visual reports from North America longitudes. As your and
other reports show, the activity of June Bootids quite certainly
occured, though remained very low with ZHR not higher than 5-7.
Perhaps it lasted during several hours starting appr. from 22 UT
June 23.

Your second observation on June 24/25 night gave 1 JBO meteor, in your
classification. But other reports tell about absence of JBO activity
in that night. Don't your think this meteor could be in a casual
alignment with JBO radiant?

Best regards, Mikhail

Hi,
I observed today (24/25) in Ondrejov, Czech Republic and it seems the
activity did not continue. 23:10-1:35 UT MetRec detected 30 meteors, 27
of them sporadic, 3 Antihelion, no JBO. The conditions were not perfect,
but become better in the second half of observation.
