Due to lack of clear nights of late I've been looking again at images taken in the past. On one there is a curious object at RA 11:16:30, Dec -61:30:00 J2000 (i.e. a little to the south-east of NGC 3603) – see crop attached. It's quite bright and so it appears routinely on images of the usual field that contains both NGC3603 and NGC3576. It has an angular measurement of about 2':25” but it would nevertheless seem to be quite large. If it lies at the same distance as NGC3603 it would be about 14 ly across. At the distance of NGC3576 it would be 6 ly. It has an interesting structure that appears to contain two, three or maybe even four loops. It would be interesting to find out what it is but, in an admittedly cursory search, I can't find any mention of it in the various catalogues that I've tried. I wonder if anyone can identify it?
