V1647 Orionis.

Abstract (from CDS):

K. Itagaki, Yamagata, Japan, reports (via S. Nakano, Sumoto; and via H. Yamaoka, Kyushu University) the apparent brightening of V1647 Ori and its associated nebula (cf. IAUCs 8284, 8354, 8396, 8600, 8681, 8694) to mag about 16.7 on an unfiltered CCD image taken on Aug. 26.789 UT with a 0.60-m f/5.7 reflector, noting that neither the variable star nor the associated nebula were visible on his survey frame taken with a 0.21-m reflector on Jan. 2.598 (limiting mag 17.5). Itagaki adds that the star appears in the USNO-B1.0 catalogue (epoch 1971.3) at blue mag 19.7 and red mag 19.5, and he provides the following precise position for V1647 Ori from his recent image: R.A. = 5h46m13s.16, Decl. = -0o06'03".6 (equinox 2000.0). Yamaoka notes that a similar quiescent brightness was noted in 2005 Oct. by Acosta-Pulido et al. (2007, A.J. 133, 2020) following its earlier outburst (to mag about 15-16) in 2004 Jan., while an earlier outburst in 1966-1967 was found in the Asiago plate collection by Aspin et al. (2006, A.J. 132, 1298).
