This record of disturbances in the Sun's chromosphere was photographed from Sydney in 1956-57, using a flare-patrol telescope.
It shows the appearance and growth of several flares and surges. Some of these disturbances are observed against the disk of the Sun. Those that are too faint for this are studied at the limb, or edge, of the Sun.
