(ISTP), M. Eselevich (ISTP), A. Pozanenko (IKI) report on behalf of
larger GRB follow-up collaboration:
We observed the field of GRB 141121A (Lien et al., GCN 17075) with
AZT-33IK telescope of Sayan observatory (Mondy) Nov., 29 starting on
(UT) 20:20:38. We obtained several images in R-filter under
unfavorable seeing. In a combined image we detect optical afterglow
(Tanga et al., GCN 17078; Perley et al., GCN 17081).
A preliminary photometry of the OT is based on nearby SDSS DR9 stars:

2014-11-29 20:20:38 8.7458 R 84*120 22.03 0.17
Due to bad seeing the photometry above includes both afterglow and
possible host (Watson et al., GCN 17105; Mazaeva et al., GCN 17111).
