PLAN
---- 
Continuing OBSID 02556, a 98.0 ksec, ACIS-I NONE - HIGH ENERGY
EMISSION FROM THE YOUNG MASSIVE CLUSTER RCW 38 - the youngest,
most embedded, massive cluster studied to date in X-rays.

Radiation environment (note 2) is currently very benign and is
forecast to remain so for the next few days.
