Further to the note on TA E-Circular 2315 issued on March 16, K. Ayani, 
Bisei Astronomical Observatory (BAO), reports that a spectrum of the new 
object in Cygnus obtained on March 16.8UT with the BAO 1.01-m telescope 
shows it to be a nova.

David Moore, Astronomy Ireland, has kindly provided links to finder 
charts for the new object:

Birger Andresen, Trondheim, Norway reports observations of the nova 
using a NAS.VSS sequence:
2007 Mar 16.999UT, 7.9  (7x50B)
2007 Mar 17.882UT, 8.4  (0.07-m refractor x24)

David Branchett, USA, relays he sighted the object on March 18 at 
10h05mUT at 8.0 (8x56B).

Maurice Gavin, Surrey, imaged the nova on Mar 18.22UT using a Canon 300D 
+ 55mm f/2 lens using a 4.8 second exposure and estimated the magnitude 
as 7.8. (unfiltered).

The following sequence (Refs: TA070318, BAAVSS N/052.01), for which a 
chart is in preparation at TAHQ, is based on a comparison star list 
supplied by Mike Simonsen:
