Saturn, Titan & storm remnant morning of March 31st

[Quark (Trevor)]

Hi All,

Imaged Saturn this morning over a 2 hrs 30 min session in an attempt to catch the remnant of the SED's storm. Cassini RPWS has not detected any SED's since March 23rd and the storm has been fading significantly.
This also occurred with the record breaking storms of 2008 & 2009 and in each instance the storm regenerated.

The seeing for the first 90 min's was good at 6 to 6 1/2 / 10 but it fell away badly over the last hour with my final capture in seeing of about 4 1/2 / 10.

I have 6 sets of RGB data and have attached 1 RGB from early in the session prior to the storm remnant rotating into view. Have also attached the 4 th and 5 th RGB's, both of which have the storm in them. It is very faint but if you look closely in the STrZ region you will see the storm.

Have also attached an animation of all 6 RGB's, the storm is in the final 3 frames. The final frame was captured in poor seeing. Titan is in all 6 of the images in the animation. There is also a very nice ripple in the NEB along its border with the EZ.

Thanks for looking.
Regards
Trevor

Hi Trevor

Now that is an amazing animation – the orbital motion of Titan is quite thrilling to see to clearly.

Your love for, and dedication to astronomy, continues to shine through in these wonderful images that you share and the descriptions and details that accompany them.

Cheers

Thanks Trevor, nice work once again ... it's been all rain and clouds here so it's good to see you had some clear sky.

cheers, Bird

Top stuff Trevor, thanks again for the view, and all the best.

Thanks Bird, the storm sure is fading, even considering that the seeing was becoming unstable as the storm came into view.

Unless it regenerates quickly I think it will fade completely. Still, if that happens there are a couple of clouds in the SEB.

Thanks Lester, these are not my best images, far from it, but they do show the storm and that's the most important thing.

Very nice work Trevor. Thanks!

Very good Trevor. You don't let lousy seeing keep you in the house. I suspected seeing would be no better than average. I checked the jet stream over NSW at http://virga.sfsu.edu/pub/jetstream/...ream_sohem.gif

Thanks Dave, the main thrust of this was to try and get something of the storm, as a bonus the animation shows a very interesting ripple along the boundary of the NEB and EZ.

It is possible to produce data of scientific value in less than optimal circumstances, this was such an occasion.

I am guided by the GFS jetstream charts as to the likelihood of obtaining anything worthwhile. I have attached the chart for March 31th 00Z, that is about mid morning for March 31st.
