Dear Friends,
A few month ago I've found a new variable on my SS Cyg images during our
Vendégcsillag-kereső (Guest Star Hunter) programme that has been
recently added into VSX:
Vend4
Mag range: 12.6 - 13.5V
Coordinates: 21 42 53.838 +43 55 36.23 (J2000.0)
Type: SR:
This variable lies only 7' disctance from V1668 Cyg (Nova Cyg 1978) and
20' from SS Cygni. It is worth to check SS Cygni CCD and DSLR images for
further photometry.

Light curve of Vend4 in TG and V based on DSLR photometry of Robert
Fidrich, Sandor Hadhazi and CCD observations by Arne Henden and Laszlo
Nemeth:

The (blended) NSVS light suggest a short period around ~60 days + my
DLSR photometry suggets a longer period around 600 days. Further
photometry is encouraged.
I've also found two more variable star candidates - Vend S611 and Vend
S613 - on my SS Cyg images only a few arc minutes from Vend4 and V1668
Cyg, so if anyone have archival CCD or DSLR images of this area, please
don't hesitate to contact me!
Clear skies,
