A Hiroshima Day vigil will be observed from 8 to 9 a.m. Saturday, Aug. 6, on the sidewalk around Park Square.

At 8:15 a.m., the time the A-bomb fissioned above Hiroshima, there will be five minutes of silence.

Signs will be provided at the Park Square vigil, or people may bring their own. Participants may stay for all or part of the hour.

Sponsors are the Berkshire Citizens for Peace and Justice, Global Issues Resource Organization, and the western Massachusetts American Friends Service Committee.
