                             FILENAMING CONVENTION 
                                    FOR THE 
                  BBSO AND GLOBAL H-ALPHA NETWORK DATA ARCHIVE

================================================================================

In general, BBSO follows the SoHO convention (see below), except that the 
observation time will have six characters with format HHMMSS instead of four 
characters, and the miscellaneous info code will be modified to represent 
different spatial resolution and calibration data.

Example:

              1         2         3
