Comments: First time using digital voice recorder, sometimes
information was clipped between "START" and "STOP".  I need to adjust
the AVR (Automatic Voice Recording) level so the recorder does not
stop during natural pauses in my speech.  The best solution may be to
repeat all information twice, including "START, START" and "STOP,
STOP" to wrap each event.

During the 121 minutes I observed, four medium speed meteors
(generally magnitude +3) appeared to emanate from within a radiant
inside the pentagon of Auriga.
