      BBSO contrast enhanced full disk CaK-line image: The image was

recorded with a 8-bit Kodak MegaPlus 1.4i CCD camera. The FWHM of

the Daystar filter amounts to 0.1 nm. This image has been corrected by

dark and flat field images, and a limb darkening estimate has been

subtracted to enhance the contrast. We use the CaK-line images to

produce a daily index of the CaK-line activity. The image was recorded

at 16:20:38 (UT) on July 03, 2003.
