      Discovered by S. Kaneko, Kakegawa, Shizuoka-ken, Japan, with on 4-s exposure on four frames using Canon 6D digital camera + f/3.2 200-mm lens under the limiting mag = 13.2, who gives mag= 9.4 on Nov. 375 UT and writes that nothing is visible at this location on a frame taken on November 4 UT.”

      Three Gaia DR1 sources (all of 20 mag) are within 6″ of the reported position of this transient.

      Spectroscopy and precise astrometry are urgently required.
