A brief report that Io was very bright at 1.7 and 2.3 microns in Jupiter
eclipse this morning (11:30 UT, 1995/03/23), indicating unusually 
high volcanic activity once again.  We lost the Jupiter occultation
itself due to hardware problems, I don't have a location for the
bright hot spot as a result.  However, it's probably not the same
outburst seen on March 2nd, as this would have been on or behind
the limb at the time.

Io was several times fainter at 2.3 microns in Jupiter eclipse a
week ago.

Follow-up photometry in Jupiter eclipse at any wavelength, or in
sunlight beyond 3 microns, whenever part of the Jupiter-facing
hemisphere of Io is visible, would be valuable- my next run isn't
till a week from now.

More Io news, including a report of strong Na emission by Trafton,
coming shortly...
