RESULT OF SOLAR 2CM WAVEBAND IN THE JOINT OBSERVATION 12-19, JAN.1989

Throughout full-waveband observation of the sun has made solar physics actively developed, a certain number of important questions about solar active region physics still remain up to now, The 22nd cycle maximum year that has come provides a golden opportunity for us to test the solar activities further, therefore a joint observation network at multiwaveband for solar radio observations of the coming solar maximum period has been made up in china.
