More than four decades of solar radio observations in Metsähovi Radio Observatory

Session: The solar sources of space weather


Aalto University Metsähovi Radio Observatory in Finland has been monitored Sun more than four decades with varying radio frequencies. Metsähovi is well known for its unique, continuous solar intensity radio map collection at the wavelength of 8 mm, which are made on the daily basis. In the past decade, the radio instrumentation has been also extended to the longer wavelengths. These instruments are also very suitable for the space weather investigations as well. In general, the radio observations are very useful tool for studying space weather phenomena. For instance, radio observations make possible to study properties of Coronal Mass Ejections (CME). The northern location of the observatory enables long, continuous observations in Summer seasons, even up to 16 hours. In this work, we present the current solar radio instrumentation of Metsähovi Radio Observatory.

All observed data, more than forty years, have been open to the public and the database is growing daily. The link to the data itself and data policy can be found from: In addition, the access to database and its structure will be shown.
