Sky conditions were good despite of a 29 m/s Subtropical Jetstream that is active. Temperature was 21 degrees Celsius,much higher than average for a winter night.
It was dry with humidity was around 40% and mild wind. There were Cirrus (Ci) high
altitude clouds that were not a problem during time of observation.
Some good RGB sets taken during its local meridian passage provided great data to be processed

Hi all,conditions once more were good enough for an IR image last
night,attached is a composite of 4 images taken between 1238UTC and
1244UTC. The GRS has set at lower right a couple of hours earlier.

Poor seeing again unfortunately. Had to push the processing to get any detail.

I would say average seeing last night despite severe Jetstream. Looking at mine and others(better) images,
it does appear that there is some activity on the SW and E edge of the GRS(best seeing in my CH4),
although I would not describe it as "major" flaking activity at this point.
My personal view is that this activity (from a timing perspective) may be related to the recent SEBs ring,whose impact may have been reduced by the chimney,
but needs to be analysed properly. A small SEBs ring has also just entered the GRS hollow(between 2 and 3 o'clock),
although I am also expecting it may be "neutralised" by the chimney(but worth watching!)
