245MHz射电爆发与太阳活动预报

Radio Burst at 245 MHz and the Forecast of Solar Activities

Boulder美国空间环境服务中心(SESC)发布245MHz射电爆发资料作为太阳活动实时警报。本文介绍这个频段射电爆发的特点、观测情况并结合云南天文台的米波射电频谱观测资料讨论这个频段的窄带射电爆发与其他太阳活动的关系。

The data of the radio burst at 245 MHz issued by the Space Environment Service Center (in Boulder, USA) are used for the real-time alert of solar activities. Some characteristics of the radio burst at the frequency of 245 MHz and the relation beween the narrow-band bursts at meter wavelengths and other solar activities are introduced. The reason for the real-time alert with the burst at 245 MHz is also discussed.
