June Bootids
Meteor shower
From Wikipedia, the free encyclopedia
The June Bootids or June Boötids (shower #170 JBO) is a meteor shower occurring every year between 22 June and 2 July that peaks around June 27. In most years their activity is weak, with a zenithal hourly rate (ZHR) of only 1 or 2. However, occasional outbursts have been seen, with the outburst of 1916 drawing attention to the previously unrecorded meteor shower. The most recent outburst occurred in 1998, when the ZHR reached 100.
