Mike McCants kindly pointed out to me that this prediction(from SAT) is 180
degrees off in azimuth from what most of the Seesat members are using.  I
didn't think about it because I am mostly using RA and DECLINATION for my
predictions but Mike's right in saying this.  Sat's azimuth is measured from
the south to the west; SWNE.
Maybe we should always indicate this when we are giving AZ/EL coordinates.

Sorry if this has given any inconvenience.
