Journey behind the black Sun

ABSTRAKT / ABSTRACT :

Research on the solar corona at the Astronomical Institute of the SAS
began with the first expedition to Poland in 1954. It continued with
the observation of the corona in 1964 in the Crimea. In 1973,
the Institute sent an eight-member solar eclipse expedition to Niger
to observe the white-light and emission corona and the intramercurial
planets during the third-longest total eclipse, lasting 7 minutes and
three seconds. The journey through the largest desert – the Sahara,
was made with two cars. The results of this trip supported corona research
in Czechoslovakia, and since 1993 in Slovakia, and thus complemented
the observations of the emission corona from the Observatory on Lomnický Štít.
The corona is the medium in which our Earth is also found. In my talk I will
introduce you to the most important experiences we had during our trip to the eclipse.
