C. Aspin, Institute for Astronomy, University of Hawai'i (UH); C. Briceno, J. Downes, F. Hernandez, and R. Rojas, Venezuela National Astronomical Observatory (VNAO); and M. Nakano, Oita University, Japan, report the following optical observations from the VNAO 1-m Stock Telescope (in V and I bands) and the UH 2.2-m telescope on Mauna Kea (in r' and i' bands). On Sept. 11 UT, the young eruptive variable star V1647 Ori – emerging from conjunction with the sun – was observed to have magnitudes V = 18.00 ± 0.15, I = 14.55 ± 0.03, and V-I = +3.45 ± 0.17. On Sept. 12 UT, V1647 Ori had magnitudes r' = 17.69 ± 0.05, i' = 15.85 ± 0.05, and r'-i' = +1.84 ± 0.07. These values are close to the maximum values reached by V1647 Ori both soon after outburst in February 2004 (cf. IAUCs 8354, 8396, 8600) and during its subsequent brightening in September 2008 (cf. IAUCs 8968, 8969).
