Full Disk Observations Of The Sun From Big Bear Solar Observatory

. The Big Bear Solar Observatory (BBSO) has a long tradition of synoptic full disk observations.Synoptic observations of contrast enhanced full disk images in the Ca II K-line have been used with greatsuccess to reproduce the H I Lyff irradiance variability observed with the Upper Atmosphere ResearchSatellite (UARS). Recent improvements in data calibration procedures and image processing techniquesenable us now to provide contrast enhanced Hff full disk images with a spatial resolution of...
