(meteorobs) Re: NM1999Aug9/10 meteors dull
The first observing night of August brought no increase in general rates
over the mid-July rates. I observed for 3:10 hours covering 130 - 440 AM
EDT (530 - 740 UT) and recorded 43 meteors in sky LM's 7.3 dropping to 7.0
by the end. Some cirrus and other clouds were coming over the city area
from offshore morning showers which brightened the sky slightly where I
was. Part of the last hour the entire NW half of the sky was cloudy. The
second hour was best with 15 meteors total, and the last hour had 7
Perseids. I quit an hour early due to boredom.
Shower members included 18 Perseids, 4 North Delta Aquarids, 2 South Delta
Aquarids, 3 South Iota Aquarids, 1 Alpha Capricornid, and 15 sporadics.
There were no Kappa Cygnids or Pisces Austrinids. None brighter than -1m
was seen. At this point the Perseid max is 2.5 days away ; there still
ought to be more Perseids on August 10 than this. I would have expected
about 10/hour in a normal year. Now I'm concerned whether the max will
continue at 2/3 normal strength this year, as it has done throughout the
90's except for 1997. The peak is sharper and the hours straddling the peak
have become poorer.
