P Cyg (2014+37A) is the prototype of massive stars with high mass outflow; it is characterized by blue-shifted emission lines along with red-shifted absorption lines. Surprisingly, we've never created a Variable Star of the Season article for this neat star - I'll have to make sure that happens soon.
Further to AAVSO Special Notice #44, 1804-18 Nova Sgr 2007 has been given the name V5558 Sgr by N. N. Samus, Institute of Astronomy, Russian Academy of Sciences, according to IAU Circular 8832 (Daniel W. E. Green, ed.).
CBET 931 (Gareth V. Williams, ed.) announces the discovery of a possible nova [V5558 Sgr] in Sagittarius by Yukio Sakurai, Mito, Ibaraki-ken, Japan, at magnitude 10.3 on two 20-s CCD exposures taken on Apr. 14.777 UT. Neither the USNO catalogue nor the Digitized Sky Survey indicates any precursor at the position of the new object.
K. Itagaki, Yamagata, Japan, provides the following position measured from his unfiltered CCD image that showed N Sgr 07 at magnitude 9.8 on Apr. 19.745 UT:
The cataclysmic variable star BZ UMa is currently experiencing an outburst which is peculiar for that star. Historically, BZ UMa has outbursts every 312 +/-114 days (although it has been much more regular in the past decade). These outbursts are similar to regular UGSU outbursts with a fast rise and a short decay over four days and are absent of any superhumps or other periodicity. However, no superoutbursts of the type also associated with UGSU stars have been detected in BZ UMa despite good observational coverage since 1972.
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
