A Method for Plotting All Sky Camera Data in Geomagnetic Coordinates

摘要

Recently the need has arisen to analyze all sky camera data in terms of geomagnetic coordinates instead of the geographic coordinate 'cell' procedure that has been used for IGY and IQSY data. The need for this new procedure came about during the analysis of all sky camera data in a conjugate point experiment where the geomagnetic position of an auroral form is of much more interest than it would be for a synoptic analysis of data in only one hemisphere. However this plotting method may also find use as a powerful tool in studies of auroral morphology. Although the method described here was developed for use with the Canadian model DA-3 all sky camera optical system, it is readily adaptable to any other system by making pertinent changes to one of the mathematical subroutines.
