(meteorobs) Observation 30/08/2005 --> Alpha Aurigids

[Daniel Gruen]

Hi!

Seems like there is a little activity going on with the Alpha 
Aurigids. When I observed yesterday night I also saw about three 
plotted meteors from a source near Alpha Aurigae, although the 
radiant was rather low in the sky (25d).

I'm definately heading out again in the early morning hours tonight.

Greetings

Daniel

Comments:
Summer is having a comeback here right at the moment, so I'm also
having a comeback into meteor observing.
Nice conditions and quite some activity from the Alpha Aurigids.
Two of the three attributed meteors were not very sure cases, though,
and the radiant was low in the sky causing a lot of computational
uncertainty - yet I believe you should all have a look when this
shower peaks in the morning hours of 1st September.
