    • SOHO LASCO COMET IMAGES V1.0

    Metadata Updated: August 22, 2025

    This data set contains images of Kreutz sungrazing comets that were obtained by the SOHO spacecraft from 1996-2005. Images have been processed by subtracting a bias, correcting for vignetting, and normalizing by the exposure time. A median of four neighboring images is then subtracted to remove the background. The resulting image has units of DN/sec. A 41x41 pixel array centered on the comet has been extracted for archiving. Future updates will contain Kreutz comets discovered since 2005, comets from the other sungrazing families (Marsden, Meyer, and Kracht), and other comets observed by SOHO.
