[1.12] Photometric Measurements of the Solar Disk at BBSO

M. F. Woodard (Big Bear Solar Observatory), K. G. Libbrecht (California Institute of Technology)

Precise photometric measurements of the Sun have been obtained with the BBSO Solar Disk Photometer (SDP) since 1993. We describe our program to characterize sunspot, facular, and non-facular contributions to the spatial and temporal variations in solar irradiance using these data.

This work is supported by NSF and NASA.
