Availability of X-class flare data from the Swedish Solar Telescope

June 14, 2018, from Aaron Reid

During the UK service run at the Swedish 1-m Solar Telescope (SST) in 2017, the observers managed to capture a series of M- and X-class flares from Active Region 12763.

This active region produced the most powerful flares of the current solar cycle, and we are pleased to announce that the first reduced dataset is available to the UK community.

The dataset was obtained from 11:55 to 12:51 UT on 2017-09-06, for an X9.3 flare, and consists of H-alpha imaging spectroscopy and Ca II 8542A spectropolarimetry, with an average cadence of 15 seconds. Currently, the H-alpha dataset has been reduced, with the Ca II 8542 data having some fringing issues in reduction due to the scale of the observed event.

Should you wish to access these data, please email aaron.reid@qub.ac.uk and m.mathioudakis@qub.ac.uk to organise transfer of the relevant files. Further flare data will be available in due course, and their release will be announced in the UKSP Newsletters.
