An American amateur astronomer Mr. J.W.McNeil has discovered an appearance of small nebula just southwest of M78 in Orion on Jan 23, 2004. This rare event has been considered that an embryo star surrounded by dark nebula had a sudden brightening, the outburst, and lighted the dark clouds up drastically. Now we're calling this new nebula "The McNeil's Nebula".
An upper comparison images show you two shots of M78 captured in Nov 2002 and Feb 2004, respectively. A right shot shows us a compact dimmed nebula indicating an arrow. The nebula has a visual brightness of about 14th or 15th magnitude, and a shape of stretched lump in north-south direction. It's a very infrequent case that such an object was discovered by amateur small telescope (3" refractor !).
