About this image

A few pencil sketches from 30th April 2022, logging the rapidly changing prom activity from AR2994 which had just rotated off disk. Apparently I missed an X-class flare/eruption that occurred at 13:47UT, an hour or so after I'd finished my observations! Sketches are mirror image, sketched "as seen", due to mirror diagonal in the optical train.
