The present most probable yields and limits are given, but limits are not absolute. Experimenters must instrument to accept a rather wide range yieldwise on the respective shots. Probable times of LASL shots will be between 1 hour ajueiembge and 1/2 hour before sunrise depending upon results of experiments to be conducted in the forward area, hour before sunrise, The probable times of UCRL shots will be 1/2 Exact shot positions will be indicated on an instrumentation chart soon to be distributed by J-6.
