A time sequence of magnetograms and velocity-grams in the H-alpha and Fe I 6569 A lines was made at a rate of 12 per hr of McMath Region 10385 from October 26 to 29, 1969. The 14 flares observed during this period were studied for configuration and changes in the magnetic and velocity fields. There was little correlation between flare position and the evolutionary changes in the photospheric magnetic and velocity field, except at large central meridian distances where the velocity observations suggested shearing at flare locations. At central meridian distances greater than 30 deg flares are located in areas of low line-of-sight photospheric velocity surrounded by higher velocity hills. The one exception was the only flare which produced a surge. Blue-shifted velocity changes in the photosphere of 0.3 to 1 km per sec were observed in localized areas at the times of 8 of 14 flares studied.
