After nearly a week of winter weather and heavy fogs, we are finally getting
a "clear sky break" but the seeing conditions are suffering badly after the
passage of a weak cold front and the approach of yet another.  Seeing is
seeming to improve tonight and my first send is attached.

Notes:

"2nd image" - dissipation of much traces of the long-lived STrZ streak
pr. the GRS.  Also note the very fine dusky oval at the s. edge of the SEBs
in the STrZ; very subtle remnant of once prominent rift within the NEB.


Here is a contrasting B & W CCD low res image which shows the very dark gray marking on the s. edge of the NEBs and associated festoon into the NEZ. The intense gray streak within the NEZ and NEBs edge is shown very clearly in the color image, with the similarly colored festoon fol. Also note the increase in the overall area of oval BA and the very pronounced pr. border now nearly coincident with the center long. of the GRS. Clay [Dr. P.

I send you a Jupiter drawing of february 12 with CM transit
of a white oval in NEB (N).
Kind regards
