2008CBET.1302....1L

W. Li and A. V. Filippenko, University of California, Berkeley, write that follow-up observations of SN 2008ax show that, after an initial decline in the B band between Mar. 4 and 5 UT, the supernova has been steadily brightening since discovery, with B = 15.3, V = 14.6, and R = 14.1 on Mar. 12.48. This is approximately 2 mag brighter than at discovery (cf. CBET 1280). The brightening rate of 2008ax is about three times that of the type-IIb supernova 1993J.
