"McNeil's Nebula" shining in old glory again!

Already on Sep. 1, The Astronomer Electronic Circular #2478 had reported an "apparent brightening of V1647 Ori and its associated (McNeil's) nebula 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," while "neither the variable star nor the associated nebula were visible" in January with a limiting mag. of 17.5. Now a picture of Oct. 12 shows the famous nebula practically as bright as in 2004 during its famous appearance out if nowhere (and discovery by an amateur astronomer). Observations followed in many wavelengths and a lot of papers were written e.g. about the bright state and the subsequent fading - now more can be learned about the eruptive variable star V1647 Orionis behind the show.

In other news a new bipolar active region on the Sun (#1005) on Oct. 12 - and 21 hi-res pictures of the Sun at various wavelengths. • New Keck pictures of Uranus and its clouds and rings, yielding clues to that planet's seasons. • Comet 29P on Oct. 12 and Oct. 10 and 51P on Oct. 12 and Oct. 10.

• The webcam images of the predicted bolide are back, together with some geometry. • We are still learning about the deep impact made by Deep Impact - and we will make the next one (on the Moon) next summer or fall with LCROSS.

• A planets conference at Cornell is being archived well. • Taking the fight against light pollution to parliament in Germany. • And remarkable pics of a plane in front of the Moon ...

This is excellent news. I thought it looked brighter, but I dont know if it was just better seeing, better optics, or really that the brightening is that apparent.
