In week 18 a new CALLISTO spectrometer has been set into operation at the observatory of Roztoky (Hvezdare, Roztoky) in the eastern part of Slovakia, near Ukraine and Poland.

Roztoky is in a very remote area, nevertheless FM- and TV-transmitters on nearby mountains produce a lot of rfi in the spectrum which is intended to observe solar radio bursts.
