With variable seeing conditions, here are some IR images obtained in a 4-day period from May 30 to June 2. 
A linear cloud interface (arrowheads) is seen on June 1, and a small CD (arrows) is visible on June 2. Both mentioned features rotate with the atmosphere.
Apparently, the "original" CD, although still small, always remained visible at a 5-day periodicity, and now seems to be again more evident. With respect to the "new" CD, only a linear interface was discriminated on June 1. This observation confirms Greg's data from that day.
