  • The Sun is a very active astronomical object. Its great exploding energy can severely affect the Earth's space environment. Since a single high energy proton is sufficient to damage the normal operation of microelectronic devices in a spacecraft, the solar proton events' forecast is very important in space weather forecast. The prediction model of previous ones needs improvement in some aspects of the choice of prediction parameters. Metric Type I burst is closely related to magnetic reconnection and coronal heating, and therefore can be used as one of the forecast parameters. The paper provides some detailed data of two typical solar eruption events, which have illustrated the correlation between Type I noise storm and proton events, CME. Yunnan Observatory has built a solar radio telescope of 11m diameter, which frequency ranges from 70MHz to 700MHz, and the resolution can reach 200kHz. Its time resolution is programmable between 20ms and 80ms, and the dynamic range can reach nearly 72dB. The radio telescope is located by Fuxian lake about 60km away from Kunming. It can not only observe Type Ⅱ-Ⅳ bursts, but also observe Type I noise, hence plays an important role in prediction of space weather.
