SOHO Recovery Updates

25 August 1998

Today appears to be the first sign of the completion of the hydrazine thawing of the tank: The tank temperature increased from 1.3 deg C to 1.9 and 2.3 deg C at 10:00 and 18:00 UT, respectively. Tank heating will continue until tomorrow morning at 10:00 UT when we will start recharging the batteries.

ESA and MMS AOCS experts arrived today at GSFC for the preparation of the attitude recovery.

Colleagues from the simulation section of ESA/ESTEC (TOS-EMM) have prepared two animations showing SOHO's estimated attitude on 23 August (45 deg) and 7 September (60 deg): http://sohowww.nascom.nasa.gov/operations/ESR7/attitude.html
