About this image

Recent marked activity has been well documented by Richard Sargent and others. After years of relative quiescence, this variable nebula (the first to be discovered) is rapidly changing. More monitoring is encouraged while Taurus is available.

Nice image Nick.

Something that nobody seems to have noticed is that the image of T Tau isn't circular. Other stars in the field are, but in this image and many others, e.g. by Grant and Richard, T Tau is noticeably asymmetric (extended North-West to South-East). This hints at some bright nebulosity very close to the star. Maybe some cleaver image processing could pick this out from the glare of the star (Nik S ???).

Mike.

This is possibly Burnham's nebula although this was first said to be south of T Tauri. It was noted by S.W. Burnham and my detailed knowledge is lacking - I'll need to check up on this. Thanks for pointing it out.

I've processed my image from Jan 31 to try to show this nebulosity very close to the star. There is a clear, crescent-like structure hidden in this glare.
