I confirm the reported brightening of BL Lac, with R = 12.52 on 1998 may 28.3
(the brightest I've seen it since last summer).  (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.
