xtype: | utype: | helio:flare.rhessi_flare_number | |
description: | An ID number, ymmddnn, e.g., 2042101 is the first flare found for 21-Apr-2002. These numbers are not time ordered, e.g., flare 2042129 occurred before 2042104. Also all sorts of problems have been noted since 2010 has started, and the energy range has been changed, resulting in more than 100 flares in certain days. Flare_ids for 2010 and beyond start with a 2 digit year, and there can be 3 digits for the flare number in a given day e.g., 100601102. |
