Shorty after setting up an intermittant batch of clouds delayed photographing until shortly before 20:00 UT. We immediatly noticed an eruptive prominence on the east-southeast limb and began photographing. The 3 images were taken towards the end of the eruption.This event occurred near south 20 at about 19:20, and continued until about 20:10. "This event was accompanied by a long-duration C2 X-ray burst, a type II sweep, and other radio output that included 120 sfu at 2695 Mhz and 8100 sfu at 245 Mhz."
