New storm appearing in the SEB. I noticed it independently and then was alerted to it on http://pvol2.ehu.eus/

From the BAA:
With Jupiter’s opposition coming up soon on Dec.7, at its highest declination for 11 years, observers may be pleased to know that activity on the planet is increasing. On Nov.11, a small, brilliant white spot in the South Equatorial Belt (SEB) initiated a new ‘mid-SEB outbreak’, which is expected to be impressive over the coming weeks and months. The first spot has already been succeeded by a second one, and there will be more such spots, arising at or near the original source (longitude L2 = 328, L3 = 105). The bright spots are believed to be giant thunderstorms, and they will successively expand and drift eastwards (i.e. to lower longitude), creating a lengthening disturbance along the belt.
