(meteorobs) Nice variety of Fireballs occured.

[stange34 at sbcglobal.net]

This was, and is, a casual comment not intended to be used for precise data 
gathering. My particular system is designed to detect unusually large & 
interesting Fireballs only and not as a fireball or meteor data base entry.

The comment was structured to indicate tonight should be a good night for 
observing.
Nothing more.
