Saturn storm in STrZ 12th June
Hi All,
Imaged the storm in the STrZ last night, not long after twilight.
The Jet stream continues to be parked over Broken Hill and high altitude cloud wafted through for the whole capture period.
This made the seeing quite variable from 4 to 6 / 10.
Captured 3 sets of R, G & B avi's, at 15 minute intervals, each channel was a capture of 900 frames. I have attached 3 RGB images with the storm marked and also an animation of those 3 RGB's. The animation demonstrates just how rapidly Saturn is rotating and shows the storms movement over a 30 minute period.
That this storm still appears quite bright and condensed under these conditions is pretty amazing.
This storm is of great scientific interest and is now clearly the second longest lived storm ever recorded on Saturn and if it can survive for another month or so will surpass the record from last years great storm.
Georg's RPWS (Radio & Plasma Wave Science) instrument on the Cassini space craft has recorded more than 200 SED (Saturn Electrostatic Discharge) episodes from this storm since mid January, this compares with 432 SED episodes produced by last years record breaking storm.
This current storm has had many gaps in SED activity, but has always been able to start up again.
The image data is vital to compare with the radio data from the RPWS instrument on Cassini for the scientific analysis of Georg's team.
Due to my local horizon, it involves a palm tree in my neighbors yard, I will only have access to the target longitude on Saturn for a few more weeks.
I realize that the quality of these images is suffering from the early evening capture time and ever decreasing altitude but they are still of scientific and historical significance.
Thanks for looking.
Regards
Trevor
