600/800mm - 24" (1/31/14): At 375x, the brighter eastern component (PGC 21386) of the disrupted, interacting pair UGC 3906 = VV 539 appeared very faint, fairly small, elongated 5:2 N-S, 25"x10". Forms a very close pair with UGC 3906 NED1 just off the SW side, 30" between centers. The fainter western component appeared as an extremely or very faint, small, irregular hazy glow, ~0.3' diameter. Often, the pair merged into a single, very irregular patch but sometimes the two galaxies sharpened up and were clearly resolved individually. Located 11' NE of mag 8.0 HD 58710. Arp 17 lies 50' SE.
