[vsnet-alert 296] outburst of V701 Tau, confirmed

[tkato@kusastro.kyoto-u.ac.jp]

   In CVC 75 (vsnet-obs 1766), T. Vanmunster reports on his detection of
an outburst of V701 Tau, probably first ever since discovery.  Available
observations (taken from CVC 75):

1995 Dec 24.951 UT, [14.6: (T. Vanmunster, 0.35-m refl., seq: GSC);
     Dec 25.847 UT,  14.5  (T. Vanmunster);
     Dec 25.866 UT,  14.5  (G. Poyner, 0.40-m refl., seq: GSC);
     Dec 25.951 UT,  14.4  (T. Vanmunster);
     Dec 25.983 UT,  14.1  (E. Broens, 0.35-m refl., seq: GSC);

   The Ouda team has just confirmed this outburst using a 60-cm telescope +
CCD, giving a rough magnitude estimate of V~14.3.  Observers should note
that the object is slightly mis-identified on the atlas by Downes & Shara
(1993).  The true object is located ~30 arcsec ESE to the position given
in their catalog -- making a regular triangle with nearby GSC 14.3 & 14.8
stars.  This identification has been confirmed by checking the discovery
report by Esastova, L.K. 1973, Astron. Tsirk. 774, which also gives the
following magnitude estimates for the 1970 outburst:

                UT        mpg
                h  m
  1970 Sep  2 22 08.7     15.0
              23 17.3     15.00
            8 21 33.0     15.69
              22 34.3     15.88
              23 35.3     15.58
            9 00 36.0     15.48
           11 23 50.0     16.24
           12 00 53.5     15.97
           26 19 57.5    <16.5
              21 05.0    <16.5

   We hope we can provide an outburst image (and accurate astrometry) next
morning.  For observers' convenience, we have put a preoutburst image
taken on Nov. 21, on which a rough position of the object is marked.
