***** 2023 Night-time Astronomical Calendar for Drexel Lynch Observatory *****

  By John Thorstensen, Dartmouth College

  This calendar is designed to provide information useful for the planning of nighttime observations.
  The format should minimize confusion;  each line gives the phenomena for a single (local!) night,
  and each line is labeled with both evening and morning (local) day and date.
  Note that all times given are LOCAL CIVIL (zone) times.  DAYLIGHT SAVINGS time is used from the
  first Sunday in April to last in October; this is the present(1986+) convention in the U.S.A.

  The rise/set times printed are the times at which the center of the object is 50 arcminutes below
  the geometrical horizon.  At the given twilight, the center of the sun is   0.0 degrees below the geometrical horizon.

  The moon positions (and rise/set times) are generated by an implementation of the Low-Precision formulae
  in the Astronomical Almanac.  The Almanac states that the error seldom exceeds 0.3 degrees.
  Topocentric corrections are included.  Comparisons with tables for Kitt Peak in the NOAO Newsletter
  indicate that the rise-set times are good to +- 2 min or so.  The moon's RA, Dec, and illuminated fraction
  are given for local midnight, regardless of whether the moon is actually up at that time.
  Note that the moonrise and moonset times are not printed if they occur near mid-day.

  The LST at evening and morning twilight are tabulated.  This gives an accurate idea of the
  range of RA's accessible during the night.

  The JD is given (severely rounded off) for local midnight.  Again, this avoids any ambiguity.

  Some credits:  The sidereal time and Julian date routines were originally coded in PL/I by
  Steve Maker of Dartmouth College.  The algorithms originated in the old American Ephemeris.
  The routine to convert JD back to calendar date is adapted from Numerical Recipes in C, by Press et al.

  CAUTIONS:  I believe that the program which generates these tables is reasonably accurate.  However,
  it has not been exhaustively tested, so you should be sure to run 'sanity checks' on the results.  Also,
  in view of the approximations used, the results should not be used when high precision is needed.
  Extension to dates far from the present (1990) should be done with great caution.  The code has
  not been tested for the eastern or southern hemishpheres.  Rise/set times are slightly incaccurate and
  rather confusing at circumpolar latitudes, where the concept of a 'night' is blurry.

  The daylight savings time conventions (if used) are quite specific (to U. S., post-1986) and subject to change.
  I know that the code has many infelicities; if you should find actual errors,please notify
  John.Thorstensen@dartmouth.edu

  Calendar for Drexel Lynch Observatory, west longitude (h.m.s) =   5 00 45, latitude (d.m) =  39 57.2
  Note that each line lists events of one night, spanning two calendar dates.  Rise/set times are given
  in Eastern time (  5 hr W), for   25 m above surroundings, DAYLIGHT time used, * shows night clocks are reset.
  Moon coords. and illum. are for local midnight, even if moon is down.  Program: John Thorstensen, Dartmouth College.
