Timo Kantola (KTU) discovered a new (eclipsing?) variable while observing HADS star V2455 Cyg. The new variable star is TYC 3590-277-1 aka BD+46 3328. By SIMBAD it is V=9.52, B5-star. It's coordinates are: 21 28 30.009 +46 40 24.97 (J2000.0). The new variable has been submitted into VSX.


The half an eclipse Timo observed on September 13, 2016 was 0.1 mag deep and lasted 3 hours. The eclipse is at least five hours long and occurs rarely or would have seen earlier by the observers who have been observing V2455 Cyg.

Good cadence would be one data point every 2 or three hours until another eclipse is detected. I will process the images in VPHOT.
