********** Mauna Loa Solar Observatory ********** OBSERVING HOURS These are defined as the time between the first and the last useful coronal scans made with the MkIII K-coronameter. This instrument levies very stringent requirements on the condition of the sky so is the most sensitive to the weather. Unless otherwise stated, it may be assumed that the H alpha observations made with the prominence monitor will be available for the same hours as the coronal data, or perhaps even longer. The format of this file is undergoing evaluation and may not be final.
