Is this a voorwerpje? That green stuff in the interacting galaxies UGC 12914/15?

Looks like one. Not familiar with candidates/known voorwerps though so maybe one for @AFJ

Well known ‘Taffy galaxy pair’, only 1 click away in SIMBAD.

Well then green is a voorwerp that is known?

looks very similar to an interaction shock wave recently discovered within the Stephan’s Quintet grouping
