    On the light-curve of OT/GRB970508
    Using the Nordic Optical Telescope, La Palma, Spain, optical studies of OT/GRB970508 were initiated 3 hours 5 minutes after the high energy event (This appears...

    Optical follow-up of GRB970508
    We report on the results of optical follow-up observations of the counterpart of GRB970508 between 7 hours and 100 days after the event. Multi-colour U, B, V...

    Optical observations of GRB 060218/SN 2006aj and its host galaxy
    The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z=0.033) and is the clearest example of a SN associated with a...

    Optical/near-IR observations of SGR 1900+14 during the May-June and Aug-Sep 1998 active periods
    We present the results of optical/IR observations obtained in the period June-October 1998. Images in the Gunn-z band were serendipitously taken just 3 days...

    Photometric study of the improved GRB 970815 error box
    An improved error box of GRB 970815 has been reported very recently (Smith et al.1999). This error box is consistent with the decaying X-ray source detected by...

    Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope
    We analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy...

    Prompt Comparison of Data for Optical Transients of Gamma-Ray Bursts
    The prompt information given by the GRB Coordinates Network (GCN) differs very much for different GRBs. We compare the optical magnitudes quoted in GCNs for...
