Analyzing MASTER database archive images of MASTER OT J033744.97+723159.0
(Lipunov et al. GCN 21720, GCN2136) we found 1 image on 2017-08-19
22:32:24.443 with clearly seen OT with unfiltered m_OT=18.6 .
During Fermi GBM trigger 521687456 inspection MASTER-Kislovodsk observed
the area RA(2000)=(18.200 +29.540) +-5.25deg GRB_error (statistical only)
on 2017-07-14 22:54:12UT with mlim=18.7 .
There is SIWFT/UVOT source (Emery et al., LVC GCN 21733, 21758) from
LIGO/VIRGO G299232 error-box (Siellez et al., GCN 21693)
with m_OT~18.7 on 2017-07-14 22:54:12UT
The archival image is available at:
http://master.sai.msu.ru/static/OT/MASTERKislovodsk20170714.jpg
We are gratiful all follow up photometry (Im et al.
GCN21723; Im et al. GCN21738; Butler et al. GCN21742, Roberts et al.
GCN 21752) and spectral (Jonker et al. GCN 21737; Roberts et al. GCN 21752; Copperwheat et al.
GCN21755; Liming Rui et al. GCN 21780) observations.
This SN IIb is placed very far from NGC 1343 galaxy center at distance
~20 kpc. The massive star progenitor in the no star formation
area is very strange.
