  : Distribution of how many solar flares – and of which class – were observed by individual instruments between 1 May 2010 and 31 October 2016 based on the timing and pointing information available (where applicable). The percentage of SSW Latest Events found is calculated relative to the number of NOAA/GOES events. Percentage of flares captured by each instrument during their respective missions are calculated against the total number of events found via SSW Latest Events.

[MEGS-A was assumed to have observed all flares from launch until it ceased operations on 26 May 2014]{}

[The total number of flares listed in the HEK between the launch of IRIS and 31 October 2016 are given in parentheses]{}
