SOHO Status Report - February 2006

SOHO Status Report - February 2006

Mission StatusThe spacecraft status is nominal, with the High Gain Antenna (HGA) Z-axis in a fixed position. 2005 was the first year since 1996 without an Emergency Sun Reacquisition (ESR). On 15 December a nominal manoeuvre (station keeping, momentum management and roll) was performed and 0.0723 kg of fuel was used. The remaining hydrazine is 118 kg. The solar array degradation after 120 months of flight is 18.04%. The SOHO presentation to the NASA Sun-Solar System Connections Senior Review took place on 14 November.
