Happy new year, everyone.  Here is a compilation of those fine images that
you have sent showing the new bright spot outbreak f. the GRS, which was
independently discovered by Jesus Sanchez and Michel Jacquesson, and
beautifully shown in images by others especially Damian Peach [and in
Tomio Akutsu's multispectral images, not included].  One can see that the
first spot appeared on Dec.19, and brightened on Dec.22; on Dec.24, it had
enlarged into a 'teardrop' and a new spot appeared at the original place,
which was double on Dec.29; another bright spot appeared at the original
place by Jan.3.  This is typical behaviour for these outbreaks.

Best wishes,
John.
