(meteorobs) Re: June Lyrids/Xi Draconids
Karl and Everyone,
The June Lyrids have been added back on to the IMO's list apparently
after the publication of their 2001 Calendar.
I would not say that anything unusual is happening unless rates exceed 5
per hour during an entire session. That certainly did not happen on the
12th for me and I doubt that rates were that high for Pierre.
Was anyone out last night? I had to work early so I was unable to watch.
