Rod Stubbings reports via Daisaku Nogami/VSNET that the cataclysmic variable GW Lib is currently in outburst, at a visual magnitude of 13.8. Follow-up observations are urgently requested. The object is located at
As reported in CBET 900, Hideo Nishimura (Miyawaki, Kakegawa, Shizuoka-ken) and Yuji Nakamura (Kameyama, Mie, Japan) have discovered a possible new nova [V2615 Oph] around magnitude 10. The position is
17:42:44.00 -23:40:35.1 J2000
Naito and Narusawa at Nishi-Harima Astronomical Observatory obtained a low-resolution spectrogram that indicates this is an Fe-II type nova, with typical P-Cyg line profiles.

A. Tago reports (CBET 890) the discovery of a possible nova [V2467 Cyg] from CCD exposures taken on March 15. The position, from Bisei Spaceguard Center images, is
RA 20:28:12.52 DEC +41:48:36.5 J2000
The brightness is about V=6.7, and the region has considerable nebulosity. We will be posting a VSP finding chart for this object in the next day or so; until then, estimate the brightness relative to nearby Tycho stars. Submit your observations as 9999+99 Nova Cyg 2007
A variable star has been discoved in TrA, according to the Central Bureau for Astronomical Telegrams (CBET No. 867, Daniel W. E. Green, ed.):
"C. Jacques, Belo Horizonte, Brazil, reports that C. Colesanti, E. Pimentel, T. Napoleao, and he have found a previously unknown variable star on CCD images obtained in the course of the Brazilian Supernovae Survey (cf. IAUC 8482). The new object is located at
Don Davies discovered a 7th magnitude eclipsing binary (GSC 02484-00592, HD74057, VSX J084246.2+315145) in May, 2005, announced on our discussion group (posting 5/27/2005), and subsequently published in Peremennye Zvezdy: http://www.astronet.ru/db/varstars/msg/1212913
The coordinates are
08:42:45.900 +31:51:41.00 J2000
and the approximate magnitude is V=7.18, with (B-V) = 0.56
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)
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."
