- What about observing here at Cornell?

on North Campus on clear Friday nights from 9 until midnight. Call the Observatory
at 5-3557 to find out if it's open.
- Find out what celestial events are taking place in the sky this week from
Sky and
Telescope magazine.
-
Astronomy Picture of the Day.
Each day a new picture is put up and explained.

phase
of the moon, or its phase at any other date.
- Find details (times, maps of visibility at different locations) about

in the next 100 years.
- Getty
thesaurus of geographic names, with longitudes and latitudes.
Note: to find the town of Borgo a Mozzano in the province of Lucca
Italy, I needed to search for "Borgo a Mozzano" as an "inhabited place" in Italy.
- Astronomical applications site of the US Naval Observatory
-
Sun Table Calculator: lots of info, including the Sun's declination (to
get that, just hit "now" and readout the Declination of the Sun).
- The Moon ephemeris
site by Keith Burnett. Notice that you have to enter the UT (Universal Time =
Greenwich mean time) date in yyyymmdd.hhmm.
It also gives the Sun's position too.
- The University of Texas at Austin Library has a
nice collection of maps and links to other sites (which I
found by doing a search at google.com).
- Need to find the map of a place according to longitude, latitude?
Google "Longitude + latitude + map" and when you locate a good site,
be sure to "zoom out" first; then zoom in to someplace interesting.
- Selected astronomical objects
