GRB 161214B
TITLE: GCN CIRCULAR
NUMBER: 20262
SUBJECT: GRB 161214B: Chante-perdrix observatory optical observations
DATE: 16/12/14 23:41:41 GMT
FROM: Alain Klotz at IRAP-CNRS-OMP <Alain.Klotz@free.fr>
Kugel F. (Chante-perdrix observatory) report:
We imaged the field of GRB 161214B detected by SWIFT
(trigger 726885) with a 400 mm telescope (F/D=3)
located at the Chante-perdrix observatory, France (IAU A77).
The CCD camera is an Atik 460EX unfiltered.
We detect the same star as Malesani et al. (GCNC 20260).
A first series images show the star 0.7 magnitude
brighter than measured in later images:
t0 + 8.1 min to t0 + 20.1 min : R = 17.2 +/- 0.3
t0 + 106.6 min to t0 + 128.6 min : R = 17.9 +/- 0.3
t0 + 131.1 min to t0 + 153.1 min : R = 17.9 +/- 0.3
Magnitudes were estimated with the nearby USNO-SA stars
and are not corrected for galactic dust extinction.
