AbstractObservations of astronomical sources provide information that can significantly enhance the utility of auroral data for scientific studies. This report presents results obtained by using Jupiter for field cross calibration of four multispectral auroral meridian scanning photometers during the 2011-2015 Northern Hemisphere winters. Seasonal average optical field-of-view and local orientation estimates are obtained with uncertainties of 0.01 and 0.1¡, respectively. Estimates of absolute sensitivity are repeatable to roughly 5g% from one month to the next, while the relative response between different wavelength channels is stable to better than 1g%. Astronomical field calibrations and darkroom calibration differences are on the order of 10g%. Atmospheric variability is the primary source of uncertainty; this may be reduced with complementary data from co-located instruments. © Author(s) 2016.
