Dodging clouds, we were able to image Io in Jupiter eclipse at
2.3 and 1.7 microns this morning (c. 13:15 UT, 1995/03/30).
Io's 2.3 micron brightness was comparable to its 95/03/23
value, perhaps a little brighter, so whatever hot spot
caused the eightfold increase in brightness between 95/03/16 and
95/03/23 is apparently still going strong.  Io was also still
conspicuous at 1.7 microns.

Because sustained brightenings like this on the Jupiter-facing
hemisphere have previously always been due to Loki, my hunch
is that we are again seeing a major Loki brightening.  However
we again missed the Jupiter occultation, due to clouds this time,
so we can't be sure.
