Special Notice #40: Possible Nova in Oph [V2615 Oph]

March 21, 2007

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.

You can draw a chart of the region using the coordinates above and VSP:

and we will add a visual sequence to that field shortly. This field will be put on the Sonoita Research Observatory calibration list, to obtain a BVRcIc calibration on the first clear night in southern Arizona. CCD observers should acquire their images, but delay reporting your observations until the calibration is available.
