AAVSO Special Notice #40

Possible Nova in 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 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:
http://www.aavso.org/observing/charts/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.
