Following posting on the Central Bureau's unconfirmed-objects webpage, S. Dvorak, Clermont, FL, U.S.A., writes that his CCD exposures taken with a 0.25-m Meade LX200 reflector (+ ST-9XE camera) on Apr. 19.36 yield mag V = 9.28 and B = 9.20 and position end figures 58s.85, 57".0 for the new variable. He adds that nothing appears at this position on a DSS red image from 1991, noting that nearby stars are obviously visible therein that have USNO-B1.0 red magnitudes around 20; he also remarks that a couple of stars at red mag about 15 nicely bracket the apparent nova. Additionally, E. Guido and G. Sostero (Remanzacco, Italy) report that their confirming CCD images taken remotely with a 0.25-m f/3.4 reflector near Mayhill, NM, on Apr. 19.39 show the new object at position figures 58s.90, 56".3 and with magnitudes B = 9.84, V = 8.90, and R = 8.30 (uncertainty ± 0.05 mag); comparison with a U.K. Schmidt red plate obtained on 1996 Sept. 8 shows nothing at this position (limiting magnitude near 20).
