"Nishiyama and Kabashima, Japan, report their discovery of a possible Milky Way nova (mag 11.2) on two 40-s unfiltered CCD frames (limiting magnitude 13.2) taken around Apr. 23.782 UT.... Following precise position for the variable: R.A. = 17h53m02s.98, Decl. = -28d12'19".4 (equinox 2000.0). Nothing is visible at this position on their survey frames taken on Apr. 2.831 (limiting mag 12.9) and 16.749 (limiting mag 13.1), nor on the Digitized Sky Survey from a red plate taken on 1996 Sept. 12 (limiting mag 17.5). A confirming image by Nishiyama and Kabashima with the 0.40-m reflector on Apr 24.673 yields mag 11.6 and position end figures 03s.00, 19".3. "

It appears to be a very reddened, very fast nova. My unfiltered DSLR shots showed nothing down to about mag 12 on Apr 22.611 and last night with deeper shots showed nothing down to mag 14 (Apr 24.695). V mags of 14.66 and 15.33 have been reported for times just after my shot. But an unfiltered CCD obs for Apr 24.673 gave mag 11.6 so maybe my camera is not picking up the reds too well.
