GRB 190613A: KAIT Optical Afterglow Confirmation
2019-06-13T05:02:42Z (5 years ago)
Weikang Zheng at UC Berkeley <>
WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on
behalf of the KAIT GRB team:

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, responded to the Swift GRB 190613A (Ambrosi et al.,
GCN 24798) starting at 734s after the burst. Observations were
performed with a sequence in the clear (roughly R), V, and I filters,
and the exposure time was 60 s per image. We detected a fading source
at the Swift/UVOT reported afterglow position (Ambrosi et al.,
GCN 24798) in all the filters. We estimate the clear band magnitude
to be ~18.2 at 764s after the burst and faded to ~19.0 at 1290s after the
Observation are on going, multi-band follow-ups are encouraged.
