I have noticed that on some of my seti units that the Right Ascension
coordinate is greater that 24 hours. For example the RA of my current
unit is 40hr 41' 6"

I am now probably showing my ignorance, but i was under the impression
that RA was an angular measure in degrees, commonly expressed as time
in hours, mins and secs, with a maximum of 24 hours?

Could anyone enlighten me?

Many thanks in Advance
