(meteorobs) Early September Meteor Observations
Greetings Fellow List Members
Came back from vacation last Thursday to glorious sunshine here in
Cirencester, the only downside of this is that there is a permanent haze
affecting limiting magnitudes at night but still I though I would try a
couple of short watches in the early evening and see what happened. The
results were not to bad for this area athough the haze with the local light
pollution did affect the limiting magnitude quite severly, it's amazing what
a difference that half magnitude can make. Anyway for what it's worth here
are my observations for the nights of the 2/3 and 3/4 September 1999. Please
excuse any faux pas I may have made with the NAMS report form as this is the
first time I've used it.
Cheers
David
