Just to bring your attention to the variable star R CrB.

 

Observations reported to AAVSO in the last week or so show a sharp drop in brightness of about a magnitude. This is clearly different from the gentle and small fluctuations observed in the last two years during the current bright state.

 

We may be about to witness a new drop into a faint state. Unfortunately it is not the best part of the year to observe R CrB, but it may well be worth finding the opportunity to have a look at it.

Only a couple years have passed since R CrB recovered from a multi-year, deep, minimum.  It will be interesting to see whether the new decline is a run-of-the-mill dip or a return to an extended period of faintness.

It is now evident that R CrB is undergoing serious change:

This is exciting!
