Bright in DSS2 Blue (0.665 μm), dims in 2MASS H (1.66 μm) and then brightens once again in WISE 4 (22 μm). Nothing in the guide

This is actually a perfect YSO candidate! A disk-free nearby star would be bright at the shorter bands and progressively fainter. (1/2)

(2/2) This one gets bright again at the long bands, suggesting dust around the star!

Thanks, I wasn't sure. So nothing wrong with it leaving the circle in DSS2 imagery. Good to know.

Ah, it is in fact a known disk! http://adsabs.harvard.edu/abs/2007ApJ...660.1556R
