Ehgamberdiev (UBAI) on behalf of the\nKU collaboration\n\nWe observed a 49 square degree of the probability area of G274296 using a\nwide-field 0.25m telescope (a piggyback system on the 0.8m telescope) at\nthe McDonald observatory, Texas, USA. The observation was performed in\nR-band, starting at 2017-02-18 11:27 (UT). A preliminary analysis of the\ndata shows the detection limit of  R ~ 17.8 mag at 5-sigma for a point\nsource detection. The covered fields are indicated below, each having a\n2.35 deg x 2.35 deg field of view centered at the coordinates. The central\nparts of the fields are covered by the 0.8m telescope simultaneously,\ncovering 46.2 arcmin x 46.2 arcmin field of view to the depths about 0.7\nmagnitude deeper than the 0.25m data. The analysis of the data is ongoing.\n\nField    RA                Dec\nG1:  12:10:00.00   40:30:00.0\nG2:  12:10:00.00   38:00:00.0\nG3:  12:10:00.00   35:30:00.0\nG4:  12:20:00.00   40:30:00.0\nG5:  12:20:00.00   38:00:00.0\nG6:  12:20:00.00   35:30:00.0\nG7:  12:30:00.00   40:30:00.0\nG8:  12:30:00.00   38:00:00.0\nG9:  12:30:00.00   35:30:00.0\n\n���",
