(meteorobs) Eta Aquariid Observations May 7, 2009

[Robert Lunsford]

This session was much less inspiring than yesterdays. This morning there was 
no marine layer so light pollution from San Diego was added to the effect of 
the nearly full moon. In addition there was some high, thin clouds plus a 
bit of smoke present.
