Hi Saturn Observers

 

Here is an observation from January 20th 2004. A fairly high contrast storm is visible. I suspect that this is a new storm as it has not appeared on recent images taken at this longitude. The sky was clear, transparency was very good 8/10, and seeing was good, 7/10 early but deteriorating through the imaging session. No wind and heavy dew. The temperature was cool in mid 40s F.
