Mottola (DLR), on\nbehalf of a larger collaboration report:\n\nWe observed the GRB 140930B (De Pasquale GCN 16857) field with the 1.23m\nCAHA telescope. The observations were carried out in the R-band on Sep\n30.82728-30.86076 UT (9.6-57.8 minutes post GRB). A very preliminary\nanalysis does not reveal any optical source consistent with the enhanced\nXRT position (Evans et al. GCN 16859) brighter than R(Vega)~21, calibrated\nagainst the USNO B1.0 catalog. A further analysis is ongoing.",
