datatype: char ucd: meta.note
xtype: utype:
description: If the event is in the SEP list complied by NOAA, it is indicated by NOAA and a time. A capital C indicates a 'confined' event associated with CME-less X-class bursts. There are five categories of events: (a) 21 SEP events that were catalogued by NOAA based on GOES observations. (b) 10 SEP events detected by GOES that were not catalogued because their peak intensity did not exceed the threshold of 10 pfu. (c) 8 prominent GOES SEP events that were not catalogued because the intensity at event onset was already above the threshold of 10 pfu due to a previous event. 5 further weak SEP events were identified on top of previous excess intensities labelled ‘(c')’. (d) GOES/EPS showed no excess signal above background after 15 X-class flares, and six further cases where no new rise was detected on top of a high intensity from a previous event (labelled ‘(d')’). (u) In four cases the GOES SEP detection was uncertain because of the high background from energetic storm particles (ESP) or because of possible confusion of SEP signatures with a previous event.
