M. Templeton, AAVSO, informs us that this variable is apparently at or near its historic minimum; a number of observers have found this star to be fainter than visual mag 14.0 since early Nov. 2008, and both visual and instrumental measures are now indicating V >/= 14.5. R CrB began its current fading episode around 2007 July 6 and faded from m_v about 6.0 to > 12.0 by 2007 Aug. 12 (cf. CBET 1052); the star has continued to fade for the past 17 months. The duration of the current episode and its depth are similar to that observed during the previous extreme fading episode that began around June 1963 and continued (with only one brief interruption) until around Dec. 1965, when R CrB faded to visual mag about 14.5.
