Abstract

The LASCO coronagraph consists of three CCD equipped telescopes taking images of up to 1024 X 1024 pixels in size. For approximately the last year a wavelet image compression has been in use for images from LASCO. The testing and performance of this compression will be discussed within the constraints of the spacecraft computer, hardware and telemetry. Effects of the image compression on the data taking, data analysis and reduction will be discussed.
