Abstract:
This contribution presents statistical results on observations of the solar corona and solar prominences
using coronagraphs at the Lomnicky Peak Observatory of the Astronomical Institute of the Slovak Academy
of Sciences in the epoch 1963 -- 2009. The mean frequency of the observing days in this epoch was 34,93%
while the maximum long-term mean frequency of the observing days was found to be in the period from August
to October. The mean frequency of the observing days suitable for observations of prominences was 34,0%,
that of the observing days suitable for observations of the emission corona was 20,03%. The mean frequency
of the observing days in which weather conditions allowed observations of the emission corona longer than
2 hours was 13,69%.
