Another Nova in Sco - Nova Sco 2007 #2
(February 21, 2007)

IAU Circular No. 8810 (Daniel W. E. Green, ed.) announces the
discovery of a possible nova in Scorpius; this object is not to be
confused with 1651-32 V1280 Sco (N Sco 2007, see AAVSO Alert Notice 346).

Coordinates provided by K. Itagaki, Yamagata, Japan:
R.A.= 16h 56m 59.35s,  Decl. = -35o 21' 50.2"  (2000.0)

Independent discoveries by:
- Yuji Nakamura, Kameyama, Mie, Japan, (via H. Yamaoka, Kyushu University)
<12.0 CCD, Feb. 14.8575 UT
9.3 CCD, Feb. 19.8593

- Hideo Nishimura, Miyawaki, Kakegawa, Japan, (via S. Nakano, Sumoto, Japan)
<11.0 photographic, Feb. 15.8 UT (T-Max 400 film)
9.2 photographic, Feb. 20.8365
9.2 photographic, Feb. 20.8370

Yamaoka's report includes that the new object is within 30" of the red star
GSC 7367.712 (R.A. = 16h 56m 58.0s, Decl. = -35o 21' 39", equinox 2000.0,
mag 13.3; variable according to ASAS).

Itagaki notes that nothing is visible at this position on the Digitized
Sky Survey, so it is likely to be a nova. Itagaki also provides an
observation of magnitude 8.8 unfiltered CCD on Feb. 20.85 UT.

An AAVSO sequence is in preparation and chart information will be announced.

Please report observations to the AAVSO as: 1650-35 N SCO 07#2

Thank you and good observing!
