Halo
-
I can't really tell if this is a spiral or elliptical. The nucleus is not distinct but color is more bluish/greenish also it seems to have a halo that could be very faint disk or could be an artifact. I more expert opinion would be appreciated as I have encountered a number of these, and I would like my classifications to be as precise as I can get them.

This galaxy is too far away to be sure if it is a spiral or an elliptical. I think most people would classify as smooth and rounded, since no details can be seen. I look it up from the 2011 results and most people (85%) marked it as smooth from the SDSS DR7 survey. We are now looking at SDSS DR8
It may be a spiral, but we will have to wait for a star survey with more resolution to classify this galaxy with more confidence.
