Digitization of the Kodaikanal Solar Photographic White Light Image Archive
Abstract
Solar telescope at Kodaikanal Obsrvatory has produced synoptic observations since 1904 while taking white light images of the sun and it has been still continuing today. The white light photographic archive has more than 44000 plates that has been acquired over 100 years. The digitization of the white light photographic plates have been carried out and completed at Kodaikanal. Here, we summarize the white light photographic data, its digitization and calibration. A few preliminary results comparing the solar cycle variations as recorded by similar archival data will be presented.
