This is NICMOS focus update as of October 28, 1998. The latest results suggest that focus in all three camera remains stable.
Starting November 16, the focus observations will be conducted twice a week to closely monitor any changes that may occur during the NICMOS warm-up period. Since the NICMOS operating temperatures in the cryocooler era will be higher, the focus results during the warm-up are expected to provide information pertinent to instrument's future operational environment.
