Re: R CrB

Indeed Howard. The recovery started around April/May this year, and R CrB is now at it's brightest level for 15 months or so. The previous partial recovery was slow, taking around 18 months to complete 4 magnitudes.  This one is rather steeper, taking just over 3 months to cover the same magnitude.  Might this mean that R CrB will get brighter this time?  We will have to wait and see.  

I've uploaded an up-to-date light curve from BAAVSS observers to the front page of the VSS web pages.  Unless anything else interesting happens I'll try to keep this plot updated weekly and post to the web site, so that we can all see if this recovery is the real deal or not.

Clears skies,

Gary

Re: R CrB

R CrB is now visible with binoculars for the first time since 2007.  As of the evening of Oct 11 it could be seen with 10x50's (from Brum) at magnitude 8.8.  The rise at the moment is ~0.1 mag every 2 days, but this could change of course in the coming days/weeks.    

This looks as if it could be the recovery we have waited 7 years for.
