The Rosse Solar-Terrestrial Observatory

Welcome to the Rosse Solar-Terrestrial Observatory (RSTO), operated by the Solar Physics Group, Trinity College Dublin. 

The observatory is dedicated to studying solar activity and its effects on Earth and it is located in the radio quiet environment of

 Birr Castle Demesne, Co. Offaly, Ireland

(53° 05' 38.9'' N, 7° 55' 12.7'' W).


We operate a number of instruments at the observatory, including e-Callisto solar radio burst monitors developed by ETH Zurich, a Sudden Ionospheric Monitor developed by Stanford University, and seismic and geomagnetic instruments provided by the Dublin Institute for Advanced Studies (DIAS).


The Irish LOFAR Consortium is considering Birr Castle Demesne as a site for a LOFAR radio telescope.
Please visit the RSTO data archives to download FITS data files or quicklook PNGs, and to view hourly-updated dynamic spectra. More information on solar activity is availaible at TCD's SolarMonitor.org.
