telescopes for total Hα solar images and for a high-precision magnetic-field map.
The main purpose of this system is to predict the occurrence of flare activities on
the solar surface through continuous observations of the solar surface and to
predict the influence of flares on the Earth. This research field is called cosmic
meteorology (Fig. 6.19).
6.5 Radio Observations
Cosmic radio waves were discovered in 1932 by K. G. Jansky of the Bell Telephone
Laboratories as cosmic noise at 20.5 MHz coming from all parts of the Milky Way.
In 1939, G. Reber, an amateur radio enthusiast and amateur astronomer, detected
radio waves similarly coming from the Milky Way at 160 MHz. He surveyed the
wide sky and delineated a rough radio map of the Milky Way in 1944. This map has
attracted major attention from astronomers around the world, and it opened up a new
research field, radio astronomy.
