The Armagh Observatory web-sites now include a substantial amount of weather and related meteorological information. This provides e-access to a variety of meteorological and climate data, including the Observatory's 210-year archive of weather records at Armagh. The Observatory web-site also increasingly makes available the results of astronomical observations carried out at Armagh, for example images of meteorological or space-weather events such as aurorae (see http://star.arm.ac.uk/images/aurora-2003-Oct/), and transient astronomical events such as occultations, eclipses and transits.
Following experimental web-casts involving transits and eclipses during 2003, further examples of time-dependent web-imaging were carried out during 2004, largely through the efforts of Apostolos Christou and Martin Murphy. An example of the Transit of Venus, on 8 June 2004, can be seen at http://arpc65.arm.ac.uk/venustransit/.
