Dear colleagues, as of 2003-06-22 6:00 UT I find the dwarf nova V478 Sco having brightened by 1.4 mag with respect to last night (based on CCD observations in the R band). The system currently (7:00 UT) is still increasing at a rate of roughly 0.05 mag/h. If the star has been in quiescence last night (the light curve seems to indicate so), and assuming R = 16 (Zwitter & Munari 1996), this would mean that roughly R = 14.5 at 2003-06-22 6:00 UT. Sorry that I can't be more specific, but I observed the system only to fill in gaps between my actual targets, and I don't have any information on suitable comparison stars of known brightness.
