Pyephem RA & DEC to GHA & DEC

In Pyephem is there a way to list Greenwich Siderial Time GST so that I can convert Right Ascension RA to Greenwich Hour Angle GHA?
>>>import ephem
>>>j=ephem.Sun()
>>>j.compute('2018/11/10 23:00:00.0')
>>>print('%s %s' % (j.ra, j.dec))
15:04:08.77 -17:19:41.4
I am using idle-python2.7, I am not familiar enough with Pyephem to determine where/when the first point of Aries is. With this I can convert ra-->gha. The above gives the ra/dec for the Sun for date/time shown
python pyephem

Could you show some example code? That would make it easier to see what exactly you need.

I found a post with a solution dec1st_2012_user 1867570, He created an object with RA=0deg and worked out the Greenwich Siderial Time GST from there. BR/JC
