Comments: Have had a large slow moving high pressure system moving over Broken Hill and have four consecutive mornings of very stable air. This is data from the first of those sessions, April 20th.
Of interest there was a bright back ground star HIP 110786 (mag 6.95) v-near Saturn. My 685nm IR data covers 75 minutes of Saturn rotation, Saturn's motion through space is also very nicely demonstrated by the movement of Saturn relative to HIP 110789 in my IR animation.
I also note a low contrast bright spot in the SEB at approx Lat-31.3 L3 316.
All data has been uploaded to PVOL with a link here to the 685nm IR animation.
