1. San Fernando Observatory/ California State University, Northridge (CSUN) Gary Chapman, Angie Cookson and Dora Preminger

2. About CSUN According to the “Master Plan” for the California State University (the CSU) there is no direct allocation of time for faculty research (unless one has a research grant) does not allow the granting of Ph. D. degrees at any State University

3. Status of Facility ● CFDT=Cartesian Full-Disk Telescope ● Daily observations (digital images) continue using CFDT1 (since 1986) and CFDT2 (since 1992). ● Observations obtained on about 60% of days. ● Fully processed images available on the Web (ftp://ftp.csun.edu/pub/SFO).ftp://ftp.csun.edu/pub/SFO ● Photometric indices available on request.

9. Scientific Justification ● Need to understand and remove solar changes from other forms of climate forcing. ● Spacecraft measurements of TSI and SSI not imaged. ● Our program measures relative changes due to solar activity. ● Our photometric indices correlate with TSI with R 2 better than 0.9.

11. Scientific Just. (cont'd) ● Our data can be used to correct S/C upsets. ● Our data can be used to connect different S/C TSI (having different scale factors). ● Imaged data necessary to understand the sources of TSI and SSI variations.

15. Student Involvement ● Students carry out research with the help of faculty and staff. ● Students are often co-authors of refereed papers. ● The most recent example is Mike Wesolowski (Wesolowski et al. Solar Phys. 2008) who is in the Ph. D. program at Waterloo University.

16. Known or Potential Users ● C. Fröhlich (VIRGO) ● S. Dewitte (DIARAD) ● J. Morrill (NRL) ● J. Pap and H. Jones ● T. Woods & SORCE team ● J. Fontenla (LASP, Boulder) ● G. DeToma (LASP) ● G. Thiullier (PICARD) ● R. Willson (ACRIMSAT)

17. Level of Support ● Personnel ● A. Cookson (½ state support) ● D. Preminger ● Students ● Technician (Mech., part state funded) ● Technician (Elec., state funded)

18. Level of Support (cont'd.) ● Cookson provides daily support of operations ● Preminger carries out scientific analyses of data and develops new math tools ● Students carry out daily observations and help with scientific analyses ● Mechanical Tech. carries out maintenance, repairs and upgrades as needed

19. Level of Support (cont'd) ● Cookson ($22K) ● Preminger ($55K) ● Students ($12K) ● Tech, mech. ($29K) ● Parts and minor equipment ($10K) ● Overhead (44%) $56K ● Total $184K
