RHESSI images and flare feature events sometimes not the same.

This link shows the issue

but it needs some more explanation.

In this case, the user has selected to show RHESSI images and the RHESSI flare feature/event. One might expect that for a given time, the RHESSI image and feature/event should be at the same place on the Sun. This is because RHESSI provides images only when there are solar flares, and solar flares occur over small portions of the Sun.

I think what is going here is that the image selector and RHESSI flare feature/event selector are both working as intended, but they are giving a non-intuitive result. The RHESSI flare feature/event selector is showing the feature/event that overlap with the observation time. The image selector for RHESSI is finding the image closest in time that matches the energy band and reconstruction method criteria. These need not be the same flare - it is possible that an image that satisfies all the defined criteria occurred at a different time and place than the RHESSI feature/event pin.

This is illustrated in this link:

The only difference in helioviewer.org between the first and second link is the change in energy band for the RHESSI image. The RHESSI image and the feature/event pin are now co-spatial, which makes intuitive sense.

The question is, what to do about this?
