IoCam1 Observations

IoCam1 has been used at the WIRO 2.3-m telescope outside Laramie and at the Perkins 1.8-m telescope at Lowell Observatory for monitoring volcanic hot spot activity on Io, for obtaining Jupiter images, and for general infrared photometry.  We also plan to use it for studies of planetary atmospheres by means of stellar occultations, but poor weather has so far frustrated those attempts.

Longer Wavelength Observations of Io

Being an InSb camera, IoCam1 can only be used at wavelengths shortward of 5.5 microns.   At these wavelengths it measures the "current" volcanic activity on Io.   However most of the energy from the hot spots is emitted by older and cooler lava flows whose peak emission comes at longer wavelengths.  In order to measure the total energy of the hot spots we have begun to apply the Jupiter occultation technique (described in the above IoCam1  Io section) to these longer wavelengths.  Our initial tests were done at WIRO using Denver University's "TNTCAM" camera, and recent results have been obtained using JPL's MIRLIN camera at the NASA Infrared Telescope Facility.
