Date: Fri, 30 Jul 93 12:46:04 PDT From: alex%avf.hepnet@Lbl.Gov (ALEX FILIPPENKO, UC BERKELEY, 510-642-1813) Subject: SN 1993J 7-30-93 Dear Mr. Kato: I have a few comments and questions about your very valuable table of photometry of SN 1993J: (1) You might want to include the Nealy measurements or updates in your next version of the table. These are included below, in IAUC 5832. (2) In your table, the 1993 03 28.90 entry for Mizser should be deleted. IAUC 5788 claims the observation corresponds to April, not March. Indeed, the observation is listed again in your table under the correct date, 1993 04 28.90. (3) In your table, where did you get the exact time at which Garcia made his discovery on March 28.9, 1993? Also, where did you get the times of the Rodriguez CCD images? The times you list differ from those given in IAUC 5731 and 5733. Could you please check them? Many thanks for your help. Your table has been of great use to the astronomical community. Sincerely, Alex Filippenko alex@bkyast.berkeley.edu **********
