We obtained 37 images in R-filter of 120 s exposure. \nWithin the Swift-XRT error circle (Bernardini  et al., GCN 17486) we \nmarginally detected optical  source with a magnitude of R=22.15+/-0.25 \nat 0.06201 days after trigger (mid time). Photometry of the source is \nbased on nearby USNO-B1.0 (R2) stars. At this time we cannot confirm \nvariability or fading nature of the source.",
