AAVSO Special Notice #166

Possible Nova in Ophiuchus
August 17, 2009
Observers S. Kiyota (Tsukuba, Japan) and L. Elenin (Moscow, Russia) have
independently confirmed the presence of a new object in Ophiuchus previously
reported on the CBAT Unconfirmed Observations Page (D.W.E. Green, editor;
see [link to www.cfa.harvard.edu] for details).
Kiyota remotely used the GRAS-G1 (0.3-m) in Mayhill, New Mexico and
reports the following magnitudes: B=13.54, JD 2455060.6329; V=11.90, JD
2455060.6341; Rc=10.42, JD 2455060.6353; Ic=9.36, JD 2455060.6365 (via
T. Kato, vsnet-alert 11399). Kiyota derives the following coordinates:
RA: 17 38 19.70 , Dec: -26 44 13.8. Elenin remotely used the Tzec Maun
0.35-m, also in Mayhill, New Mexico and reports the following magnitudes:
B=13.67, JD 2455060.7247; V=12.43, JD 2455060.7230; Rc=10.78,
JD 2455060.7184 (private communication). Elenin also derived coordinates
with the following position end figures: RA: 19.72s , Dec: 13.7" (+/- 0.6
arcseconds RMS).

This object has no counterpart in either the USNO-B1.0 or 2MASS catalogs;
however, a faint source is visible at these coordinates in both the DSS-II
and 2MASS J images. The object is within the plane of the Milky Way and
is in a very dense star field; as T. Kato points out in vsnet-alert 11399,
this object is highly reddened, with (B-V) = +1.6. It has not yet been
spectroscopically confirmed as a nova; the AAVSO will issue an Alert Notice
if and when confirmation arrives and the object is formally designated as
a nova. Observations of this possible nova are encouraged.


The J2000 coordinates of this source (from L. Elenin) are as follows:

RA: 17 38 19.72 , Dec: -26 44 13.7 (+/- 0.6 arcsec)


Finder charts for this object may be plotted by entering the coordinates

AAVSO Special Notice #165

Dwarf nova-like outburst of the old nova X Ser
August 17, 2009
T. Kato reports in vsnet-alert 11397 that the Catalina Sky Survey has
detected a dwarf nova-like outburst in the old nova X Ser (N Ser 1903).
Catalina reports this star was at magnitude 14.18 on JD 2455059.94
(2009 August 16.44). The AAVSO observational record for this star is
sparse, with fewer than 20 observations in the International Database.
However, the star was reported to be at similar magnitudes in the past
(14.0, JD 2449603.6, J. Nordby, Moorhead, Minnesota; 14.1, JD 2450359.3,
M. Fonovich, Plomin, Croatia; see also Honeycutt, Robertson, and Turner,
1998, Astronomical Journal 115, 2527).

Observations of X Ser are strongly encouraged to fully cover the current outburst. We also encourage more long-term monitoring of X Ser to better
constrain its long-term behavior. Both visual monitoring and instrumental
photometry are needed.


X Ser is located at the following (J2000) coordinates:

RA: 16 19 17.7 , Dec: -02 29 29


Customized charts for X Ser may be generated using AAVSO VSP:
