[vsnet-alert 450] Possible fading of V482 Cyg

[Taichi Kato <tkato>]

   As noted by Gary Poyner in vsnet-obs messages, the R CrB star V482 Cyg
seems to be fading slowly.  Available observations from vsnet-obs postings:

   1996 June  2.991   10.9  G. Poyner
              4.940   11.4  A. Diepvens
              4.985   10.9  G. Poyner
              6.954   11.4  A. Diepvens
              7.0     11.5  L. Kiss
              7.032   10.9  G. Poyner
              7.976   11.4  A. Diepvens
              8.997   10.9  G. Poyner
             12.939   11.0  R. J. Bouma
             12.994   11.5  A. Diepvens
             12.997   11.0  G. Poyner
             14.0792  11.2  M. Biesmans
             14.963   11.8  A. Diepvens
             15.006   11.1  G. Poyner
             15.9     11.6  L. Kiss
             16.007   11.0  G. Poyner
             18.005   11.2  G. Poyner
             22.985   11.4  G. Poyner

   V482 Cyg experienced at least four distinct fading episodes between
1987 and 1991.  The current reported trend may represent another precursor
to major fading(s), as was observed before the start of the 1987 episode.
