Please find attached a short observation of Jupiter made last night.
It was a lovely calm transparent morning and seeing was rather good to begin with,
although it declined shortly before the clouds came up at 0443UT.
There were a number of interesting things on the disk,these include the following:
-SPR vague greyish region
-There appeared to be remnants of both a SSSTB and a SSTB though not uniformly across the disk
-STB brownish,STZ a brghter yellowish region
-STropB visible with some darker spots/sections within
-Oval BA just coming onto the disk,no reall colour detected but the border surrounding it
and interacting with the STB (and STRopB?) was rather dark and a greyish brown in colour.
Some bright spots quite close to BA in the STZ.
-SEB rather active. In general there appears to be a SEBn and
a SEBs with a SEBz which seems to have a slight diagonal component at this longitude.
SEB seemed to be rather active with many subtle structures of different shades and intensity present.
-EZ contained a number of bluish zones
-NEB rather active,all manner of darker structures and lighter regions seemed to be present within the belt.
The NEBs was the base for a number of festoons while the NEBn seemed to be rather irregular
with perhaps a number of subtle shadings extending into the NTropZ
-NTropZ seemed to have a slight yellowish cast tonight
-NTB visible and seemed to have a dark northern edge.
-NTZ reasonably bright,slightly yellow in colour
-NNTB also contained a number of darker sections.
-NPR greyish,there seemed to be many subtle structures present here too
but it was hard to capture them successfully.
The drawing shows how they appear in general.
Occutlation/Graze of Star HIP 34583.
0355UT: It became clear that Jupiter was approaching a star (all of the Galileans could be accounted for).
0404UT: Stellarium showed this to be the star HIP 34583,a +7.55 magnitude star of spectral class K2.
0407UT: HIP 34583 was very close to Jupiter's SPR. Alas seeing really started to drop off and the clouds started to
come in. I was shortly forced to stop observing at I have no way of knowing whether an occultation occurred or if
it was simply a graze. My suspicion was that it was a graze,but I am not certain.
Closed down at 0443UT. I had hoped to make an observation of Mars,but the clouds put a stop to that idea.

Attached is one of the images obtained this morning with the ASI120MC one shot color video camera
coupled to the CPC-1100EdgeHD telescope with a 2x Barlow lens giving f/23.
Video data was acquired using Firecapture,processed in AutoStakkert!2 and Registax6.
Seeing was variable,from poor to fair. Estimated 5/10 for the attached image. Transparency also fair.
