Re: (meteorobs) Re: June Lyrids
Hello folks,
I had another look at my June video data and found 5 suspicious meteors, some
of which may belong to the supposed Xi Draconid radiant. Unfortunately,
most of them are relatively short, making it difficult to get accurate data.
The logfile entries are given below, images are available on request. I had
no information about the expected geocentric velocity, but these meteors
converge best with a values around 40 km/s. Given a base solar longitude
of 85 deg, the convergence point lies at about alpha=282 deg and delta=59 deg.
Cheers, Sirko
