Hi Jupiter observers
Here is an observation from February 1st 2003 at 07:08 UT. Europa can be
seen about to exit the globe of Jupiter. This close to opposition, the disk
of Europa and it's shadow are nearly on top of one another and the shadow
seems to be partially occulted by Europa. The NTB is very weak and can only
be seen in a few segmented strips. The transparency was fair, 4/10 with some
light fog and seeing was fair, 5/10 with no wind and heavy dew. The weather
was cool with the temperatures in the low 50s F in the early mourning hours.
