(meteorobs) Limiting Magnitude Tool
A tool to aid observers in locating appropriate star fields for use in
making estimates of limiting magnitude is now available at the website of
the North American Meteor Network. The "Limiting Magnitude Field Locator and
Calculator" was kindly provided by Peter Girard of ESRI-Boston, a company
that sells geographic information systems (GIS) software.
The tool utilizes the predefined star count areas published by the
International Meteor Organization, and will provide three different fields
to use during an observing session. Optionally, it can be used to determine
the limiting magnitude by entering the number of stars counted in the field.
This results in the limiting magnitude for that field being displayed.
Finally, the webpage also generates the average limiting magnitude for
fields that are used.
Observers are encouraged to check out the "Limiting Magnitude Field Locator
and Calculator" at the home page of the North American Meteor Network
(http://web.infoavedot net/~meteorobs). Comments, suggestions and any problems
encountered may be sent to me at the address below.
Clear skies!
