Introduction

Using the search capabilities outlines in a previous nugget, we can now do a retrospective analysis to see how successful - or otherwise - our coordinated observations have been during Solar Cycle 24.

Figure 1: Plot of Solar Cycles 23 and 24 (average monthly sunspot number) with mission durations overplotted. The two vertical dotted lines denote the 6.5 year time range considered for this study. Note that SDO/EVE MEGS-A and IRIS only overlapped for ~11 months.
