I had an opportunity this morning to view Jupiter for an hour and a half. The Great Red Spot (GRS) would be transiting the CM, so I was hoping to get a glimpse of Red Spot Jr, which is currently close to the senior storm. Seeing was only average which ultimately limited what I could see.
When I began the session at 0800 UT, Io was just emerging from a transit across the Jovian disk. It appeared like a little blister on the preceding limb near the South Equatorial Belt (SEB). At the same time, the GRS was well in from the following limb.
In integrated light (IL). the North Equatorial Belt (NEB) and the SEB both appeared brownish-gray while the North Tropical Zone (NTrZ) and the North Temperate Belt (NTB) were a salmon pink color. The GRS was very pale without a well defined edge (sometimes known as the GRS Hollow).
Using Wratten #11 and #80A filters as well as looking in IL, I tried to make out RS Jr (also known as Oval BA) but I could not resolve it as a separate storm. Perhaps if the seeing had allowed higher magnification I might have been successful.
However, the GRS had a very odd appearance--roundish instead of the usual oval shape and more shaded in the southern portion. It took me a little while to understand that the round shape was evidence of Red Spot Jr. which is currently just to the south of the GRS.
Long story short, I can't say that I saw RS JR/Oval BA directly in a recognizable form, but I can say I saw a sign of it. Other notes are with the sketch. Good luck with your own Jupiter observations.
