Dear ASCA users, It was requested by M. Corcoran to observe Eta Carinae (AO-6 Priority-1target) as early as possible during current low state; they worry otherwise they must wait for 5.5 years to the next low state. Accepting this rtequest we have installed the observation on December 24 by replacing with the target, Z System F6 (PI: N. Yamasaki, Priority-C of AO-5) once allocated in the span. The observation of Z System F6 was now dropped out.
