Illumination by the Moon

(direct light only; a general planetary ephemeris is also possible)

Year:   Month:   Day:   Hour:   Minute:
Longitude: (western as -)   Latitude:   Your Time - UTC:  h
Extinction in zenith:  cmag  (city air has rather 35 cmag)
Compute illumination of the surface with its normal pointing at: Azimuth from S:   Ang. height:

Another option is to use your own command line (ev. overriding all previous data):

 This is a result of the programme 

planet (available as a part of a package

pas_jh.zip (1.2 MB) --
the needed Pascal units themselves are unzipped within 
this directory, the whole tree of my programmes within

this directory)

 with a command line:
