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:

(add another moments, with a step of days)

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

(`?' gives help, adding `k3' would give a luminous flux density as if it were no Earth).

> far  <  gives distance of the body from the Earth (in Earth radii for Moon),
> L-LS <  difference of the ecliptical longitude of the body
           from that of the Sun (if positive, the body is east from the Sun),
> old  <  for Moon is  (L-LS / 360 degrees) *  29.53059 days
> Illu.<  horizontal direct illumination by the object
> b    <  planetographic latitude of the subterrestrial point
> PA   <  position angle of the central meridian of the planet
> long <  planetographic longitude of the subterrestrial point
> PhA  <  "phase angle", i.e., angle Sun-body-Earth.
> col. <  for Moon is the so-called colongitudo (its PhA=abs(L-LS))

This is a result of the programme planet (available as a part of a package (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:
