[Taichi Kato <tkato>]

Possible fading of R CrB

   Minoru Sato (VSOLJ) has pointed out the slight fading of R CrB, which
seems to have been confirmed by other observers.  Although the change is
small, observers are requested to monitor this star intensively in order
to see whether this change leads to a major decline.
