The SORCE SIM instrument has been observing the declining phase of SC 23, the
quiescent solar minimum period and the rise to the current SC 24 in the 240-2400 nm
range. Due to issues related to an aging spacecraft, additional corrections are required
after September of 2010 to account for temperature instability and wavelength shifts
associated with power cycling the instrument on every orbit are needed to correct the
instruments response. These corrections and additional and further analysis of
degradation mechanisms and measurement equations will be presented.
