CI Aql fading

   CCD observations by the VSNET collaboration team (cf. vsnet-campaign)
indicate that the recurrent nova CI Aql is again fading.

   Selected nightly avaraged data from Kyoto observations:

   YYYYMMDD(UT)   V-C   err   N
   20000514.795 -0.549 0.033  47 C
   20000515.769 -0.808 0.019 255 C
   20000520.773  0.170 0.028 136 C

   The object has faded by 1.0 mag in these five days.  In addition to
the already suggested short-term modulations, there seem to be a longer
period oscillations (with a timescale of ~10 days), superimposed on
the nova fading.  Further observations are strongly encouraged.
