The “Butterfly diagram” of RHESSI flare latitudes versus time. The colour and letters indicate the different background subtracted GOES class of each flare and the vertical dotted-dash line shows the transition from Cycle 23 to Cycle 24 during the middle of 2008. The vertical gaps (for instance start of 2012 and middle of 2014) are due to extended periods when the RHESSI detector were off due to annealing.
