CANOPUS Auroral Network - ground-based array of instruments monitoring auroral-related
events in support of international space science. It is operated
and maintained by the Canadian Space Agency.
Global Oscillation Network Group - a community-based program to conduct a detailed study of solar
internal structure and dynamics using helioseismology. In order
to exploit this new technique, GONG has developed a six-station
(Big Bear, CA; Mauna Loa, HI; Learmonth, Australia; Udaipur, India;
Canary Island and Chile) network of extremely sensitive, and stable
velocity imagers located around the Earth to obtain nearly continuous
observation of the SUN's "five-minute" oscillations, or pulsations.

Ulysses Mission Operations Team - based at the Jet Propulsion Laboratory in California. Provides
information about past, present, and future operations of the
spacecraft. The Ulysses Mission is a joint undertaking between
the European Space Agency (ESA) and the National Aeronautics and
Space Administration (NASA). Its goal is the exploration of the
Sun's environment far out of the ecliptic plane. Ulysses is the
only spacecraft to have visited this unique region above and below
the poles of the Sun

Total Eclipse of the Sun - August 11, 1999 Cornwall UK, Europe, and Asia. The final total solar eclipse
of the millennium, in 1999 (there is none in 2000) is a once-in-a-lifetime
chance for Europeans to see the most spectacular astronomical
phenomenon there is. On Wednesday, August 11, 1999, a total eclipse
of the Sun will be visible from the Isles of Scilly, the Cornish
mainland, Alderney in the Channel Islands, and much of mainland
Europe. Apart from Finland in 1990, the last total eclipse in
Europe was in 1961; and not since 1927 has the United Kingdom
mainland seen a total eclipse. This is the last chance to observe
a total eclipse in the British Isles before the 23rd of September
2090. Yes, 2090! Even Europe will not see such an event again
until 2081.
1998 Solar Eclipse - On Thursday, 1998 February 26, a total eclipse of the Sun was
visible from within a narrow corridor which traverses the Western
Hemisphere. The path of the Moon's umbral shadow began in the
Pacific, continues through northern South America and the Caribbean
Sea, and ends at sunset off the Atlantic coast of Africa. A partial
eclipse was seen within the much broader path of the Moon's penumbral
shadow, which includes parts of the United States and eastern
Canada, Mexico, Central America and the northern half of South
America.
Sunspot Numbers - In 1848 Rudolph Wolf devised a daily method of estimating solar
activity by counting the number of individual spots and groups
of spots on the face of the sun. Wolf chose to compute his sunspot
number by adding 10 times the number of groups to the total count
of individual spots, because neither quantity alone completely
captured the level of activity. Today, Wolf sunspot counts continue,
since no other index of the sun's activity reaches into the past
as far and as continuously. Site include material on Solar and
Interplanetary Phenomenon, Flare-Associated Events, and Cosmic
Rays
Sunspots - Research and observations from the UK suggest that sunspots
are formed by rising tubes of magnetic flux that break through
the Sun's. Diagrams, MPEGs and graphs relating to this topic.
