Opening Metsähovi Radio Observatory’s solar observations database

Joni Tammi, Aalto University Metsähovi Radio Observatory

The year 2018 marked the 40th anniversary of solar radio observations at Aalto University Metsähovi Radio Observatory in Finland. The observatory’s 14-metre radio telescope has been used to create brightness maps mainly at 37 GHz since 1978; additionally, a 1.8-metre radio telescope has been monitoring the total brightness at 11.2 GHz since 2000. These data, together with essential data processing tools, documentation, metadata, etc., will be made directly and openly available online during the fall 2019. Here we will review the opened datasets, explain the structure and details of the data, and give instructions for accessing the data.
