IAU Circular No. 8810 (Daniel W. E. Green, ed.) announces the discovery of a possible nova in Scorpius; this object [V1281 Sco] 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

Special Notice #33: V1280 Scorpii = Nova Scorpii 2007

February 7, 2007

IAUC 8803 announces a new nova in Scorpius, independently discovered by Y. Nakamura and Y. Sakurai. The position is

16:57:40.91 -32:20:36.4 J2000

and the unfiltered magnitude is about 8.3 (T. Krajci, 2007-02-06).

Spectra indicate blue color, no emission blueward of 540nm, but Halpha emission with P-Cyg profile.

Report observations to the AAVSO as: 9999+99 V1280 Sco. Please be sure to indicate what you used for comparison stars.

Thank you for your astronomical efforts and contributions!

Special Notice #32: Possible Nova in Centaurus [V1065 Cen]

January 24, 2007

William Liller, Vina del Mar, Chile, reports his discovery of a possible nova; confirmation and spectra are needed. According to Bill, "its approximate magnitude is 8.2. It appears on two photos taken near Jan 23.354 UT with Kodak TP film, an orange filter and an 85mm lens. Nothing brighter than magnitude 11.5 was seen at this position on Jan 15.36. Nothing seen at this position on the Real Sky Digitized Southern Sky Survey."

Coordinates (from Liller): R.A. = 11h 43.2m Dec. = -58d 03' (2000)

Special Notice #26: Possible Minor Outburst of 0324+43 GK Persei

December 15, 2006

Coordinates: 03:31:11.82 +43:54:16.8 (2000.0)

Recent observations of the old nova intermediate polar magnetic catclysmic variable GK Per (Nova Per 1901) show the star brighter than minimum. However, it is too early to tell if an outburst is underway.
