Sat, 13 Jun 2015 - R CrB plummets!

No sooner had we published the news item The slow fade of R CrB continues on June 4th, when the fade then accelerated !

Having recorded R CrB at mag 8.5 on June 5th, Tony Markham then saw it drop to mag 9.1 by June 9th.

The accompanying BAA VSS light curve shows R CrB dropping further to around mag 10.0 by June 12th.

Thus R CrB has now dropped below binocular visibility. If you are able to observe it telescopically, your observations would be very welcome.

Here is a finder chart (approx 3 deg by 2 deg, with north at the top) showing the telescopic comparison stars down to 11th magnitude:
