We report a detection of a transient in M31 positionally coincident with the PNV J00424914+4116401 (see ATel #8787). The current transient was first detected on Nov. 11.106 UT using the Danish 1.54-m telescope at La Silla and is located at R.A. = 0h42m49s.23, Decl. = +41o16'39".9 (equinox 2000.0), which is 55.3" east and 31.4" north of the center of M31. Although the difference between the measured positions of the PNV J00424914+4116401 and the current transient (caused likely by its position close to the bright M31 center and proximity of brighter object located only 3" away) is 1.0", they are very likely the same object caught during the two outbursts. This finding was supported by direct comparison of the images of the PNV J00424914+4116401 and the current transient.
The PNV J00424914+4116401 has observed a peak magnitude R = 17.9 ± 0.3 between 2016 Mar. 6 - 17th and faded below the detection limit of R ~ 19 mag two weeks later. The following R-band magnitudes were obtained during the current outburst using the Danish 1.54-m telescope at La Silla (DK154) and the 0.65-m telescope at Ondrejov (D65):
2016 Nov. 8.153 UT, [18.8 (D65); 9.858, [19.0 (D65); 11.106, 18.8 ± 0.2 (DK154); 13.048, 18.4 ± 0.15 (DK154); 13.730, 18.5 ± 0.4 (D65); 14.729, 18.3 ± 0.3 (D65); 14.744, 18.1 ± 0.3 (D65).
This work is based (in part) on data collected with the Danish 1.54-m telescope at the ESO La Silla Observatory.
