Aida's "disturbed green mystery" object
« on: July 16, 2009, 10:12:06 pm »
Trawling around in navigate tonight, I came across an oddly coloured disturbed object/galaxy. It has no ID, but searching on the nearest object, I found Aida had previously posted it in the newbies thread. Then, the only suggestion as to what it might be was a "disturbed green mystery!".
It is quite close to a star, but the other objects in the vicinity don't seem to be tinted green. So I thought I'd post it again here to see if anyone has any new ideas?

Tsering, it may well be a Voorwerpje candidate if we got the spectra.  Liz, when you can take a look at this please!!

Here it is a little more centered.  No photometric circle or spectra.

Hmmmmm. It must have strong emission somewhere in the r band, either H-alpha at low redshift or [O III] at higher redshift. Here are the SDSS griz images all lined up the same way. The "elephant trunk" to the southeast only shows up in the one filter (which is the one mapped to green in the SDSS color images.

(Make note to self to file for followup someday).

The colour looks similar, doesn't it. Is it a pea?

not a true pea I think.
the spectrum of peas shows a very high OIII peak and a flat baseline.
