Duration of R CRB's Current Minimum
I noted last evening that R CRB's recent attempt at a recovery from its long current minimum clearly has failed once more. A quick check of century-plus lightcurve makes it look like the current minimum is decidedly the longest in duration ever recorded for this odd variable. Plus, there seems little real indication that there could be any return to maximum light in the near future (even though these stars are known for being highly unpredictable).
I'm unsure just what the record is for the duration of the longest minimum state of any confirmed R CRB-type star, but I would think that in the current instance R CRB itself likely is close to, or presently setting it.
