From here, a user can search by:
 
-
* GOES Class (B, C, M, X)
 
-
* Maximum Energy Detected by RHESSI
 
-
* Whether RHESSI observed most of the impulsive phase, or as long as it observed part of it
 
-
* Flare location (disc vs. limb) based on AIA locations
 
-
* Whether it was observed by other instruments such as EVE MEGS-A or MEGS-B, the 3 Hinode instruments or IRIS
 
-
Clicking on a flare in the list that is returned will bring up a plot of the metadata of the RHESSI and GOES lightcurves with longer wavelength observations overlaid. An EUV image is also shown with reduced FOVs overplotted. This plot, and a .sav file containing the metadata, is also downloadable.

The SSWIDL widget searches a pre-generated lookup table to instantly return a list of flares corresponding to the users criteria. The construction of the table begins with the SSW Latest Events list, which is accessible via the HEK. This list is based on the familiar NOAA GOES event list except it contains the location information of each flare based on SDO/AIA 131A difference images. This is required to compare with limited FOV instruments.

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.
