The Rosse Solar-Terrestrial Observatory

Welcome to the Rosse Observatory operated by the School of Physics, 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 host the Irish Low Frequency Radio Telescope (I-LOFAR) and operate a number of instruments, including e-Callisto solar radio burst monitors developed by ETH Zurich, a Sudden Ionospheric Monitor developed by Stanford University, and a magnetometer provided by the Dublin Institute for Advanced Studies (DIAS).
