Nova Cyg 2001 No. 2

Dear Colleagues,

   As some of you have already observing, a bright nova (and looks still
brightening!) is discovered in Cygnus! (IAUC 7686)

   The discovery was made by Akihiko Tago, Okayama, Japan on his patrol
films taken on 18.599 and 18.603 UT.  The information was relayed by
A. Nakamira immediately to the CBAT.  Upon Nakamura's request, K. Ayani,
Bisei Observatory, took a spectrum, which shows emission lines of H-alpha
and beta, with pronouced P Cyg-profile.  This is very characteristic of
a spectrun of a nova at premaximum stage (even if it is not in the earliest
stage).  The nova has further risen to the 6-th magnitude object now,
confirming the suggestion from spectroscopy.  The brightening of the nova
was very rapid.  A. Nakamura further noted that the magnitude at the
discovery was determined using Tycho sequence, and is directly comparable
to subsequent obseravation.

   The position is
   21h 03m 02s.00   (J2000.0, measured by H. Abe)
   +48o 45' 52".9

   Congratulations to Tago-san!  Until the object receives the permanent
GCVS name, please report the object as CYGnova2001-2 in the VSNET reporting
format.
