Abstract. We present and discuss first preliminary results obtained with the European Observation Network. This network consists 9 observatories in the Czech Republic, Germany and Bulgaria and is involved into the BACODINE activities since April 1, 1994. We also discuss related problems such as background of unknown variable stars and suggest strategy for works in this direction. The presence of (unknown) variable stars in the GRB error boxes with typical BACODINE sizes (more than 10 deg) in deep frames (deeper than 15 - 16 mag) can be also used as a measure confirming the suitability of the searching method.
