To avoid excessive heating of the feed legs, the prime focus regions, and the cables to the prime focus, the telescope will not be pointed to within 15 degrees of the sun. The following table lists the apparent RA and Dec of the Sun on the first of each month (I have ignored the small year-to-year changes due to precession). Observers are encouraged to use this information to specify their proposal requests for observing time.
