GCN KONUS Light Curves

This page changes after each GRB detected by KONUS, so hit the   <reload>   button NOW.

  1. Recent GCN/Konus Lightcurves
  2. Past GCN/Konus Lightcurves

This is the archive of all the GCN/KONUS Notices and Light Curves in their original form as they were sent out to the GCN sites. The light curves are available in Postscript, GIF, JPEG, and numerical text formats (The first column of text format is used to generate the postscript, gif and jpeg files, where line1 = GRB date, line2 = hh:mm:sec.sss, lines 3-n = x,y values. The second column of text is a newly added format where line1 = KONUS1or2 detector number, date ,time, and a comment, line2 = keV range, line3 = average background value, line4 = comment, lines 5-n = x,y values). ). Older KONUS Light Curves have been added from the launch date until the GCN/KONUS Notices began, and any Light Curves that were not generated by the GCN/KONUS Notices are now being added through an automated process.

The light curves are the count rate in the KONUS_1 or KONUS_2 detectors in the 50-200 keV bandpass. The KONUS_1 detector views the southern ecliptic hemisphere, and KONUS_2 views the northern ecliptic hemisphere. The time sampling is 64 msec bins. The telemetry data from KONUS is available in 1-25 hours after the trigger time. Automated software within the GCN system captures these daily dumps, scans for triggers, extracts the rate information, and produces the light curves.

There is no immediate identification of the trigger type for the most recent events. Most light curves are for actual GRBs, but like BATSE there are other non-astrophysical mechanisms which can cause count-rate increases in the detector and initiate a trigger. Within two weeks, the Detector number, Event type, and Trigger number are supplied by Sergei Golenetskii (Ioffe Institute) and are added to the table.

Please note that because of spacecraft telemetry downlink operations, about 1 in 10 triggers are downloaded twice. Hense, since the automated scripts are not smart enough to recognize this duplication, there will be a few duplicated entries in the table below. On rare occasions a human will remove these duplicate entries.

NOTE: All files on this site have been checked due to a report of a high count rate at 33.280 seconds in some files. Many files have been corrected. You should check any files downloaded before February 28, 2002. The Light Curves that were generated by the GCN/KONUS Notices were NOT affected.
