   Berto Monard has kindly provided new observations.  The phenomenon
indeed appears to be transient brightening lasting for 1 day.

   V-band observations also confirmed this event (the object faded by
1.4 mag in one day!)

PS. Received a comment on multicolor photometry.  "Unfiltered photometry
would do the best": please supply "for detecting short-term modulations".
Sorry for the lack of explanation.  Of course, snapshot multicolor photometry
is always valuable.
