Dear

I have found on:

"Dear vsnet members, 
I have just sent a following report to CBAT. 
Congraturations, Mr. Tago! 
K. Ayani and T. Kawabata at Bisei Astronomical Observatory (BAO), Okayama,
Japan, obtained a low resolution spectrum (470-680nm) of the possible nova,
which was discovered by A. Tago, on July 14.6 UT with BAO 1.01-m telescope.
Strong, broad H-alpha and H-beta lines are visible. The H-alpha line has a
FWHM of about 3400 km/s and a equivalent width of about 50 nm. "
--------------------------------------------

My comment.
I think that FWHM of about 3400 km/s and a equivalent width of about 50 nm
is wrong, I think that must be 50 angstrom or 5 nm. May be I have 
wrong, but v/c=3400/300000=approximation 1/100 
(H-alpha/100=approximation 5 nm=50 angstrom).

I am sorry if I have done mistake.

Best regards, Zorko Vicar
