V1363 CYGNI (=Q1996/065)
Gary Poyner e-mailed on Sept 13 that he had detected a possible
very faint outburst of the Recurrent Object V1363 Cyg as follows:

Sep 12.896  mv=15.9
    12.942     15.9

Tonny Vanmunster in Belgium subsequently reported on VSNET that he
had confirmed the outburst by CCD at the CBA Belgium (25-cm f/6.3
SCT and ST-7 CCD). The CCD images were obtained under very poor
conditions (strong winds, clouds), but clearly show the presence
of a faint object. A rough analysis of an unfiltered CCD image,
obtained at 23h19m UT (1996 Sep 12) yields a magnitude of 16.5
(using the 15.60 comp. star on the TA sequence).

Tonny adds that V1363 Cyg is not visible on earlier CCD images,
obtained at the CBA Belgium, although they have a similar limiting
magnitude. This further proves the reality of the object. The
Outburst Activity Database on Selected Cataclysmic Variables
contains no entries on past outbursts of this object.

Taichi Kato, Japan e-mails:
According to the discovery paper (Ric. Astr. Vol. 8, No. 10),
V1363 Cyg showed very peculiar behavior unlike other dwarf novae.

       JD       magnitude
     (+2400000)
  around 32400: fainter than 17.5
  around 32600: observed at 13-14 for about 40 days
                then faded again to 16-<17.5
         32950: started to brighten slowly
         33000-33200: 14-15 mag
                then slowly faded to mag 17 around 33600
         33980: started to brighten, reaching a maxium of 13.5
                around 34000
         34100: 15-16 mag
         34150: 13.5, then faded to
  around 34200: 14-14.5
         34220: faded further to mag 16
         34230: brightened again to mag 14
                then faded very slowly to mag 18 around 35000

>From the time-scale of variations, the object looks like an
anti-dwarf nova (like MV Lyr and KR Aur) rather than usual Z Cam
stars.  Spectroscopic observation by Bruch and Schimpke 1992 (A&AS
93, 419) confirmed its cataclysmic nature. The recent faint state
of this object is remniscent of the "superminimum" of MV Lyr. The
ROSAT Bright Source J2006.2+2342 may be identified with this CV.
Close follow-up observations are urged to see if the star may
become active again.
