Object name: HH389
This interesting field in Cygnus just under 6 degrees due north of the North American Nebula. I've centered on the variable star V1331 Cyg. It harbors HH389 and lights up the reflection nebula around it GN 20.59.5.01 forming an arc around the variable star. SIMBAD notes that while some consider the star an FU Orionis class star they say this is unlikely though it is a young stellar object so likely a star just coming onto the main sequence. It has a G5 spectrum so a bit redder than our sun. The reflection nebula is the dust left from the creation of the star that's lit by the star it created. As such it takes on pretty much the color of the illuminating star. Radiation pressure from the star likely created the arc as it pushed away the dusty cocoon of its birth. The star seems out of center indicating this dust may be piling up at a shock front as it moves through the very dusty interstellar medium in this part of the galaxy. I found no papers on this so am just speculating here.
