70th anniversary of the start of radio astronomy in Poland
70 years ago, the first radio astronomy measurements were carried out in Kraków.
Yesterday we celebrated exactly the 70th anniversary of the beginning of radio astronomy research in Poland. On June 30, 1954, our then-employees, including Adam Strzałkowski and Oleg Czyżewski, observed the Sun (and phenomena related to its eclipse) at radio wavelengths of roughly a meter, using a 5-meter antenna placed on the site of Fort Skała, the present-day headquarters of Jagiellonian University's Astronomical Observatory in Kraków.
