Websurf is designed to provide a range of astronomical information
in both pre-calculated and dynamic forms. Our Info option provides links to
access Astronomical & Calendarial Sheets and maps for Solar & Lunar Eclipses, First
Sighting of New Moon data and Time Zone maps. The dynamical information covers rise/set
times, azimuth and altitudes, Islamic Prayer Times, First Sighting of New Crescent Moon,
Moon Phases, Equinoxes & Solstices and an Almanac giving solar, lunar and planetary data
for a specific location and time.
Websurf underwent an upgrade at the beginning of 2010. Please use
the Feedback option to report any problems. This site should be regarded as a work
in progress and options available now may be replaced in the future.
