   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       On Friday, Dec. 23, 1994 at 1007Z, two science observations on ESTR
       #1 were not recorded while data was being gathered. Two Subsequent
       science observations on ESTR #1 did not record properly. In order to
       prevent the possible additional loss of science data, ESTR #2 and #3
       were assigned as the science tape recorders while ESTR #1 was
       reassigned as the engineering tape recorder. The anomaly on ESTR #1
       is being investigated. (See Note 1.2)
