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.
