The bright (FUV= 12.65, NUV= 12.43 mag -> Previous outburst? Dwarf nova??) UV source GALEX J185803.7+170125 is only 1.4" from the transient's reported position. This UV source is probably identical with USNO-B1.0 1070-0419935 (18 mag). --- Patrick Schmeer (Bischmisheim, Germany)

Mag.= 13.2, position end figures 03s.64, 27".0 observed by T. Noguchi, Chiba-ken, Japan, using 0.23-m f/6.3 Schmidt Cassegrain + unfiltered CCD, who put an image at http://park8.wakwak.com/~ngc/images/PNVinAql_20170121.jpg.




2017 01 22.8581

Photometry results were V=12.77, Rc=12.65 and Ic=12.96 with 0.25m SCT + Apogee Alta F47 CCD. Rc color was slightly brighter than V and Ic but it might be due to high air mass. Seiichiro Kiyota (Kamagaya, Japan)
