    We have received reports from different observers that alpha
  Cyg (Deneb)
  looks slightly fainter than usual.  Could someone confirm?

Taichi:
I cannot confirm the possible fading of alpha Cyg.  I visually compared alpha Cyg to Vega, Altair, and gam Cyg.  I estimate alpha Cyg at V=1.3 on 05/09/2003 10:00UT using these comparison stars.  SIMBAD gives V=1.25 for alpha Cyg.
