[24] The SEB revival: Final interim report (Sep 17th, 2011.)


Report no.24 (2011 Sep.17):
The SEB Revival: final interim report

John Rogers (British Astronomical Association)
with data from Hans-Jörg Mettig, Gianluigi Adamoli, Michel Jacquesson & Marco Vedovato (JUPOS project).

Summary:
Here we continue the account of the SEB Revival from mid-Jan. until the end of the apparition in 2011 March.  The previously reported types of activity in the source, central branch, and southern branch, are confirmed and extended.  It is especially notable that the SEB(S) became repopulated by slowly-retrograding chains of white ovals even as dark spots were still retrograding much faster.  The origin of the northern branch, and interactions of all three branches with the GRS, are also described.  The main parameters of this SEB Revival as a whole are summarised.

We are very grateful to all the observers, whose details will all be listed in Report no.25.
