Astronomy for Astrologers
there" or overhead, on the star maps elsewhere in this
section. Your LST (Local Sidereal Time) may be
expressed in Hours-Minutes-Seconds (HMS), which you
will find along the edge of these maps, or in Degrees-
Minutes-Seconds (DMS) of arc (rather than time). These,
also, are given on the maps. (HMS may be converted to
DMS simply by multiplying by 15, and DMS may be
converted to HMS by dividing by 15).
Meridian Alignment
For those of you with access to a standard star map,
you might like to look up your RAMC or LST and locate
the right-ascension meridian that was overhead at your
birth, which gives you the direction in space to which
your birth location was pointed or oriented. All of the
stars and points along the line of right ascension,
running from top to bottom on this map, were in line with
the geographic meridian for your birth. The diagram will
illustrate this.
