(meteorobs) Video Observations July 28, 2008

[Robert Lunsford]

Below are the results obtained by the AMS Meteor Camera on the morning of
July 28, 2008. These results should not be directly compared to visual
observations, rather it offers an insight on the overall activity of each
shower for this morning. The listed limiting magnitude estimates are visual
and the camera has a fixed field of view of 62 degrees, less than that of
the visual observer. The camera can pick up stars near magnitude +6.0 and
meteors of perhaps +5.0 and brighter.

Rates were significantly higher this morning than on the 26th. The moon was
less of a problem plus the limiting magnitude was improved due to less light
pollution.
