Extract

A class 2 flare began on 1968 June 9 in the active region near 17°N 40°E, at about 00h15m U.T., maximum 00h37m, terminating about 02h30m. The event was recorded at Culgoora with the 5-inch flare-patrol and 12-inch chromo-spheric telescopes at solar diameters and frame intervals of 16 mm/10 s and 17 cm/3 s respectively. Both telescopes used Halle filters, pass bands about 0.5Å centred on Hα, and Duplopan 35 mm film. The seeing was mediocre, with occasional fairly good frames.
