Kospal, Konkoly Observatory, Budapest, reports on a CBET that CCD images at various wavelengths of V1647 Ori (=McNeill's object near Messier 78, see TA E-Circular 1967: editor), obtained between Oct. 5 and Nov. 20 at the Mountain Station of Konkoly Observatory using the 1-m RCC telescope show that this variable star has started a very rapid fading: approximately 1 mag/month in I_C as opposed to 0.1 mag/month previously. According to the colour changes, the rapid fading is not caused by increasing extinction. Assuming the cause is intrinsic and the fading rate remains unchanged, the star will return to the pre-outburst state by mid-December 2005.
