U.Quadri, L.Strabla and R.Girelli report:
We imaged the fields of GRB 131127B
(von Kienlin, GCN 15528; Singer & Kasliwal,
GCN 15524; Golenetskii et al., GCN 15530) with the robotic
telescope of (IAU station 565) Bassano Bresciano
Observatory, Italy (www.osservatoriobassano.org).
The observations started 27h 55m. after the
Fermi-GBM trigger (Fermi407254341) , with our
schmidt telescope D=320/400 mm F/D=3.1.
Weather conditions were good.
We co-added 3 series of 5 unfiltered exposures
of 120 sec each.
We detected the candidate couterpart of iPTFecv
(Singer et al, GCN 15524) at the following
position (+/- 1 arcsec):
RA (J2000.0) = 20h 31m 47.79s
DEC(J2000.0) = +00d 59m 22.8s
The results of our photometry are:
Date UT Exp R-mag
Middle (s) (rough)
2013 11 28.75862 600 18.84 +/- 0.2
2013 11 28.76579 600 18.85 +/- 0.2
2013 11 28.77297 600 19.08 +/- 0.3
Magnitudes were estimated with the USNO-B1 cat.
and are not corrected for galactic dust extinction.
