Micro-Flares: Small Solar Eruptions

Solar eruptions, flares, like these are the result of a rapid conversion of magnetic energy, stored in the Sun's magnetic field, into heat and motion. Small flares, while much less flashy than large flares, occur often and are observed by IRIS frequently. More observations like these provide data with which we can uncover the detailed nature of these spectacular solar events.
