C. Aspin, Gemini Observatory; and B. Reipurth, University of Hawaii, report on observations made at the Gemini 8-m telescope on Mauna Kea. GMOS optical images obtained on Aug. 30 UT show that V1647 Ori (cf. IAUC 8354), upon its re-emergence in the morning twilight, has faded by approximately 1 magnitude in the r' passband since Jan. 8. McNeil's nebula itself (cf. IAUC 8284) has also faded considerably. The duration of the outburst so far exceeds 21 months. Optical spectra still show strong H-alpha emission with blue-shifted absorption. Both the depth and extent of the strong absorption component are less than previously observed, suggesting that the powerful wind is weakening.
