[Bill Godley]

A nice show, including some bright ORIs and an EGE.  Considering my somewhate poor LMs I think activity was rather high.

NOTES:  Thin cirrus limiting seeing somewhat first 1/2 or so of the count.   The EGE was well-positioned to clearly determine it was genuine rather than an ORI.  Skies cleared completely at 09:25.  Most exciting were the three meteors literally on top of one another at 09:54.
