report on behalf of the Lick/KAIT GW follow-up team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, observed the 90% region of the gravitational-wave
event S190901ap (GCN 25606; GCN 25614) detected by LIGO/Virgo. More
than one thousand galaxies were selected from the Glade catalog V1.0
(Dalya et al., 2018, MNRAS, 479, 2374; http://aquarius.elte.hu/glade/)
according to their priority score. KAIT observed 156 of them on
Sep. 02 UT starting at 3.8 hours after the trigger, and additional
143 on Sep. 03 UT starting at 1.37 days after the trigger, according
to their priority scores and elevation visibility, with each clear-filter
exposure time being 60 s. Our typical limiting mag is 19.0. No viable
counterparts were identified and the analysis is ongoing. A full list
of galaxies observed by KAIT is given below.
In addition, we took 7x180s clear band images of ZTF19abvizsw/AT2019pim
(Kool et al., GCN 25616), now considered as an unrelated GRB optical
afterglows candidate (Burdge et al., GCN 25639; Wei et al., GCN 25640;
Perley et al., GCN 25643; Salmaso et al., GCN 25650; Levan et al.,
GCN 25653; Becerra et al., GCN 25655; Ho et al., GCN 25658). We estimate
the clear band magnitude to be ~21.3 +/- 0.2 mag in our co-added image at
Sep. 04.23 UT, calibrated to PS1 catalog.
