(reports of this brightening have been reported by AAVSO and Taichi Kato (conveying others' observations.) Summarizing the recent values listed on my web page: 1998 5 05.2 1998.340 13.21 1998 5 14.2 1998.364 13.39 1998 5 16.2 1998.370 13.32 1998 5 18.3 1998.375 13.07 1998 5 19.2 1998.378 13.12 1998 5 20.2 1998.381 13.36 1998 5 23.2 1998.389 13.48 1998 5 28.3 1998.403 12.52 It is thus worth watching at optical wavelengths.
