the flare development.

However, it is difficult to keep track of which flares have been observed by which instruments. While most currently operational missions have their own individual flare lists (*e.g.* Hinode Flare Catalog: @wata12 or *Solar Dynamics Observatory* (SDO)/*EUV Variability Experiment* (EVE): @hock12), it was only recently that the first inter-instrument catalog became available, hosted by New Jersey Institute of Technology (NJIT)[^1] [@sady17]. The *Max Millennium Program for Solar Flare Research* (see @bloo16 for a recent review) and others have aimed to coordinate ground- and space-based instrumentation to observe a flaring active region simultaneously in order to optimize the scientific return. However, this can be difficult due to factors such as coordinating across multiple time zones, planning schedules being uploaded days in advance, ground-based seeing conditions, competing scientific priorities, and so on.

Therefore when a solar flare is known to have been observed by a combination of instruments, the event can receive considerable attention as a consequence. A notable recent example of this is the 29 March 2014 X-class flare, which was observed by four space-based observatories and one ground based telescope[^2]. Consequently there have been 23 refereed publications that discuss this flare, according to a NASA ADS fulltext
