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

A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy
