Extended time series of Solar Activity Indices (ESAI) is database including observational, synthetic and simulated sets to study Solar magnetic field variations and their influence on the Earth. ESAI extend the ordinary lengths of some traditional indices of solar activity: sunspot areas, Wolf numbers (equatorial component of magnetic field of the Sun), polar faculae numbers (polar component), mean latitudes, N-S asymmetry of hemispheres (location of activity). Series . ...

In this collaborative group activity, teams of students use the internet to find moon myths in a number of cultures and then try to discern the astronomy behind each myth. There is a section on researching moon missions that just seems tacked on to curry favor with NASA. [e,m] . ... A field test version with good activities and background information about the Saturn system and the Cassini mission, which is scheduled to enter Saturn orbit in 2004. ...

Geomagnetic storms and substorms are a natural hazard similar to hurricanes, floods etc. ... Solar and geomagnetic activity also probably influences the Earth's climate and human health. ... Under southward directed IMF the Earth's magnetosphere is open to input from the solar wind flow. ... Since practical importance of solar wind measurements was recognized, a number of approaches was developed for prediction of the geomagnetic activity basing on the solar wind data. ...

spaceweb@oulu.fi - last update: 13 September 1998, 1130 UT (RR) . Ground based magnetometer measurements are used to derive several indices that describe magnetic activity in the Earth 's environment. aa , AE , Ak(Hel) , Kp , Dst , PC , MT . ... AE index is an auroral electrojet index obtained from a number (usually greater than 10) of stations distributed in local time in the latitude region that is typical of the northern hemisphere auroral zone (Davis and Sugiura, 1966). ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...
