White-light coronameter images from the High Altitude Observatory Mauna Loa Solar Observatory (Hawaii) |
Regular observations of the Sun at 127 MHz started at TRAO (then a section
in the Astronomical Observatory) in 1958 with a single dish, 12 m in
diameter. Later, since 1960, an interferometer of 23 m long baseline was
used for the purpose. The main objective of this patrol is to measure
the intensity of the continuum radio emission.
However some distinctive
events (bursts of radiation) produced by the active Sun are also
measured. This frequency (127 MHz) is one of the lowest systematically
reported, and now the collected data constitute certainly the longest
series at such a low frequency.
