Hi All,
Imaged Saturn June 20th in good seeing. Have data covering 2 hours 6 minutes of Saturn rotation and all of it is very good.
There is considerable activity within the EZ in 685nm IR and CH4 data with the Southern hemisphere being particularly interesting.
Have seven 9 minute 685nm IR data sets at 21 minutes centres along with six 9 minutes CH4 data sets also at 21 minute centres.
All data has been uploaded to PVOL with links here to the animations.

Of particularly interest, the 685nm IR data resolves two large low contrast bright spots far south at approx Lat-50 and –44 with the CH4 also resolving a bright spot at similar Latitude and L3 . Previously, other than within the EZ, I have not been able to positively identify possible small scale detail from noise within my CH4 data for Saturn. On this occasion with so many CH4 data sets at set intervals I have had success with the CH4 animation being the clincher. Also note Tethys is beginning to transit towards the end of the session.
Detail resolved in these data by Latitide.
A prominent dark EZ feature at approx Lat+9.5 L1 334.6 in CH4 data.
A prominent dark elongated EZ feature at approx Lat-7.6 L1 9.0 in 685nm IR data.
A prominent large bright spot on the EZ / SEB border at approx Lat-17.1 L1 5.5 in 685nm IR data.
A compact bright spot at approx Lat-32.2 L3 205.3 in 685nm IR data.
A large low contrast bright spot at approx Lat-43.9 L3 254.2 in 685nm IR data.
A bright spot at approx Lat-46.9 L3 252.3 in CH4 data.
A large low contrast bright spot at approx Lat-49.6 L3 249 in 685nm IR data.
