王者归来 2011L4重新被地面捕捉到

It's back and going OK. Managed to image this comet at very low altitude in a
fast-brightening sky this morning. Trailed a bit but nonetheless the comet is
clearly visible. Position should improve day by day until the Moon kills it.

I added some star magnitudes to the image, TYC and rubbery. The comet
definitely appears brighter than mag 10, how much brighter is difficult to say
because any extended coma would have been washed out with the sky brightness,
other factors aside.http://i727.photobucket.com/albums/ww271/Rob_Kau/C2011L418Dec2012text.jpgCheers -
