Astronomy Tools
The following tools make use of the
Skycalendar and
Skycalc programs by
J. R. Thorstensen. I wrote the Web interfaces as well as some
other code (such as for the Moon Phase) to get what you see here.
- Moon Phase Page
-
Produces an image of the moon for a given date.
- Astronomical Sky Calendar
-
The page generates a calendar for the given range of months which
contains, for each day, the Julian Date, Sun rise & set times, Moon rise
& set times and percent illumination, etc.
- Daily Almanac
-
Lots of useful information, like sun rise and set, moon phase and
position, etc. for a specific date.
- Hourly Airmass Tables
-
Provides the airmass for a star (or other object) for each
hour in a given night.
- Object Seasonal Observability
-
Lists the rise,set, and transit times for an object on the
full and new moons (i.e. bimonthly) over a period of time.
- Planetary Positions
-
Lists the positions of the major planets for a given date.
