The SOHO CAL-SO program funded by the Low Cost Access to Space NASA grant NNG05WC09G is in the year of no-cost-extension. Thus far under this grant we have had two successful rocket underflights that return high quality EUV data and three successful calibrations of the SEM instrument at NIST. Analysis of the data from all underflights was completed in Dec 2008. The results will be presented at the Fall AGU Meeting (San Francisco, Dec 2008): Darrell Judge, Leonid Didkovsky, Seth Wieman, and Pradip Gangopadhyay. "13 Years of SOHO/CELIAS/SEM Calibrated Solar Extreme Ultraviolet Irradiance Data". The SEM calibrated data website at USC (http://www.usc.edu/dept/space_science) will be updated in Dec 2008 - Jan 2009 to publish the new version of the SEM data (Ver 3.1 of Dec 11, 2008). This work was partially supported by NASA grant NNG05WC09G; USC# 53-4882-3600 and NASA grant NASA-NNX08AM94G; USC# 53-4882-2820

The ESP flight and rocket instruments have been successfully calibrated at NIST and delivered to LASP and later to Goddard SFC. The flight instrument is currently assembled to the EVE and is a part of SDO. SDO is at the GSFC and is ready for its launch in 2009.

The Space Sciences Center is currently working (year two of two) on the Project to design and build a new OFS (NASA grant NASA-NNX07AN37G; USC# 53-4882-4640). The laboratory design is about to be fabricated at the USC mechanical shop. After assembling the focusing system, laboratory tests with EUV monochromator will begin in Jan 2009.

Degradation-Free Spectrometers (DFS) for Solar Physics

Work is currently in the first year of the three-year Project (NASA-NNX08BA12G; USC# 53-4882-5920). SSC is underway to optimize the existing designs of DFSs to improve the efficiency and to reduce the size and weight of the instruments. Work to implement the electronics of these two new spectrometers to the existing CAL-SO payload was started in summer of 2008.
