Interactive Access to BATSE Solar Flare Data

Since the launch of the Compton GRO, the SDAC has maintained an on-line interactive computer facility that provides the international solar physics community with quick-look access to the BATSE 4-channel LAD rates with 1-second time resolution, as well as scientific support in the interpretation of these data. The facility displays flare catalog entries, plots quick-look displays of orbital data and flare time profiles, dumps the data in ASCII or binary format files for remote retrieval, and lists BATSE solar viewing time intervals. The database contains data from April 1991 to May 2000. The spacecraft reentered the atmosphere on June 4, 2000.

Access to our anonymous ftp site is available here. Please note that we no longer allow anonymous interactive access to the database through the batse account. Members of the scientific community may request an account or specific data products not available online by emailing

We have prepared a detailed description of the BATSE data and our facility. Look here for answers to your questions about how the data is processed, how to get access, and other topics.

Noninteractive Access to BATSE Solar Flare Light Curves

To view the flare catalog and access PostScript plots of the light curves via FTP, click on a year to view the flare catalog for that year.

New: GIF versions of the BATSE Solar Flare Light Curve plots

To view the flare catalog and access GIF plots of the light curves via FTP, click on a year to view the flare catalog for that year.

Monthly Event Listings

To access monthly BATSE event listings containing start and peak time, duration, peak counts, burst trigger, and triggertime seconds, click on relevant year.

NOTE: The filename format for the event listings has been changed. Files will now be in a YYMM_batse.list format, instead of MMMYY_batse.list. For instance, AUG94_batse.list is now 9408_batse.list. Both formats are still available for old files, but the new format will be used in the creation of new files.
