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.
