Seeing was not good here this morning, it reminded me of winter - cold, windy and low clouds. There was enough clear sky to grab 4 runs between 4am and 4.30am, and they show some detail in the belts in both hemispheres.

ps I know the image is mirrored left-to-right, I forgot to fix that before I built the animation and couldn't bring myself to re-do it :-)

Red channel data, 3 minutes per capture @ 22fps with 5x powermate.

Hi Bird,
Well done again.

Clearly structure at 35 Sth and 35 Nth.
The structure at 35 Sth looks way to bright and well defined to just be a persistent spot.

I know Georg is saying that the SED's activity has stopped but this seems clear evidence of storm structure. Back in December the orbit of Cassini was such that there could well have been SED's not being detected by the RPWS instrument.

Keep up the good work.

Regards
Trevor

Hi Bird,

Noticed, when I scrolled down to the labeling on your animation that this is from Jan 9th. I see you have your script organized to display CM III data and it agrees with the data from the ephemeris generator.

You were very close to the bright spot that appears in my animation from the same morning, yours was from 17:01 to 17:30 and mine was from 17:20 to 18:10. Seems to be a fair bit of activity.

Regards
Trevor

Hi Bird,

The penny just dropped regarding the date for our obs.
From last Feb through to July all of my Saturn data was captured before midnight and so the my local date was relevant, obviously now our imaging, with respect to UTC is occurring still on the previous day.

Regards

Yeah, that catches me out as well if I'm not careful. I've tried to automate as much of the date and time stuff as possible cause I used to get the day wrong on these early-morning imaging runs :-)

cheers, Bird
