*MASTER OT J011613.54+640832.0 - new R CrB variable*

MASTER-Amur auto-detection system discovered OT source at (RA, Dec) =3D 01h
16m 13.54s +64d 08m 32.0s on 2013-04-26.69067 UT. The OT unfiltered
magnitude is 14.1m (limit 16.9m). The OT is seen in 2 images. We have
reference image without OT on 2012-04-18.558 UT with unfiltered m_lim=3D16.=
2.

The object is identical to IRAS 01129+6352 =3D 2MASS 01161363+6408319
(J=3D11.79+/-0.02, H=3D9.16+/-0.02, K=3D7.01+/-0.02). It is included in the
Catalogue enriched with R CrB stars (Tisserand, 2012) based on near-IR
(2MASS) and mid-infrared (WISE) characteristics. However, no variability
was mentioned before.

The star is present in USNO-B catalog as USNO-B1.0 1541-0038015 (RA=3D01 16
13.593, Dec=3D+64 08 32.12, R1=3D18.30, R2=3D17.14, I=3D15.56). Color-combi=
ned DSS
finder chart is uploaded
tohttp://master.sai.msu.ru/static/OT/J011613+640832-BRIR5x5.jpg (5´x5´
FOV). The object was at low state during Palomar survey showing little
variability between POSS-I and POSS-II plates.

On the other hand, the object was likely at a high state in 1999-2000
during NSVS (ROTSE-I) observations. The light curve of NSVS
1689547has
the variable nearly constant with median ROTSE Mag 13.407, Mag Scatter
0.095 and Median Error 0.074. Such a behavior is consistent with R CrB
nature of this object, as suggested by Tisserand.

Follow up photometry and spectroscopy are encouraged. The discovery and
reference images are available
