Seeing is very poor and variable; focusing very tough but first clear
evening in over two weeks for imaging!

Seeing very poor.  Interesting dichotomy within the north and south halves
of the NEB; considerable turbulence in southern 1/2 of this belt, with a
clear delineation of both activity and intensity....result of opposing
currents?

Seeing very poor.  Two very nice and interesting dusky ovals in this
image....note the one embedded in the s. edge of the SEBs right on the CM
(about 345d II); another VERY prominent oval (or is it perhaps TWO) is
visible west of the CM in the NEZ...it is very large and dark and shows
development since last seen (System I).


Well, April 1 has come and gone almost like a bad April Fool's joke.  The
sky was beautifully clear and crisp with the moon not interfering until
after about 4:15 UT....but the seeing was the worst I have seen perhaps all
year.  This final image from tonight was taken through some distant trees
toward the end of the sequence of some 30 exposures....

Seeing worst possible, with Jupiter viewed behind trees to west.  Very
distinct bluish oval area in NEZ near CM in this image; this has been noted
on earlier dates.  Note the very dusky activity south of the GRS.
