Nanoflares, energy releases powered by small magnetic reconnection events in the solar coronal loops, have long been hypothesized as one of the sources for heating the solar corona to million-degree temperatures. Much of the evidence for this has been indirect, and difficult to distinguish from other hypothesized mechanisms.

In these visualizations, we present observational evidence of the IRIS imager detecting nanoflares in a coronal loop. In the IRIS imager, overlaid on AIA 304 angstrom imagery, the events stand out as jet-like protrusions roughly perpendicular to the curve of the coronal loop.

In this data, we see several strong nano-flare events near the 14:43 timestamp.
