Comments: Imaged Saturn October 9th targeting a CM transit of AV. My ephemeris predicted a CM transit at 11:40 UTC so I framed my session to have 9 min 685nm IR data sets centered on 11:40 UTC with sets also centered 30 min either side. As it turned out seeing was reasonable so was capturing data 51 min earlier. Have AV, it is faint but is surrounded by its signature brighter annulus. I measure it to be at approx Lat+42.1 L3 184.6 the ephemeris predicted an L3 of 185. This is is verification of the accuracy of the ephemeris and extends the period from 23 days to 40 days; from my August 30th data through to this October 9th data with the reference used being the HST OPAL IR data from September 22nd. These IR data also resolve a dark spot in the NNTeZ at approx Lat+66.2 L3 119, an elogated bright spot is resolved immediately below the dark spot at approx Lat+60.4 L3 120.8. A mid latitude bright spot is resolved at approx Lat+31.2 l3 170 both in IR and R data All wavelengths resolve at least two EZ/NEB ripples at approx Lat+14.9 L1 44.8 and Lat+14.6 L1 342.1 R and RGB data resolve a bright spot in the NNTeB at approx Lat+63.4 L3 132.4. R and RGB data resolve a v-bright elongated linear feature in the Southern Hemisphere at approx lat-31.1 L3 158.5. RGB data resolves a bright mid latitude spot at approx Lat+30.2 L3 210. CH4 data also resolves a bright spot on the Southern edge of the NTeB at approx Lat+45.9 L3 182.1.
