(meteorobs) July 23/24 1998 observation
Marco Langbroek and others,
I observe from my backyard the night of July 23/24 for total 2.85 teff.
My limiting magnitude reached 5.7. The data is now decoded so I can
verify the Alpha Cygnids I observed. Besides SPO, the ACY were highest
activity with 5 seen. Even the Perseids did not do as well. I was
careful not to get PER and ACY mixed up. I made sure speed, alignment,
and distance from radiant matched before calling them. This is not
overly high activity, but with suburban 5.7 skies, I wonder how many
more could have been seen under much darker skies. ACY were surely
more active than my nights out around July 18.
As mentioned before, highlight was a nice mag. -4 ACY. Also saw a -1
NDA. The south complex of radiants was still a bit slow but is
slowly showing up. One annoyance during the night was the beams
of mega spotlights from the city that kept doing circles over and
over. Total 27 meteors for the period.
Just about to leave now for a 24/25 observation. Will report back
tomorrow.
