The above image has been processed for automatic flare patrol. To avoid saturation of the image, the camera that acquires these images will adjust the exposure time of the CCD during solar flares, this will result in the image appearing darker during flare activity.The automatic flare detection technique is described in this document on solar flare patrol. You can view the latest unprocessed H-Alpha image from Culgoora Observatory here.
