第2009卡林顿周太阳活动的初步分析

介绍了第2009卡林顿周大黑子群AR484，AR486和AR488产生的太阳活动以及这些太阳活动对地球空间环境造成的影响。依据对太阳活动的统计研究，简要分析了三个大黑子群活动的差异。分析结果指出，关注某一时期太阳活动的活动经度带以及太阳活动在某一半球的主次是解决太阳活动短期预报非常重要的思路。

Primary Analysis of the Solar Activities During Carrington Rotation 2009

The solar activities produced by active regions 484, 486 and 488 and the impacts on space environment produced by these solar activities are introduced. The difference among the three huge sunspot groups are studied briefly based on the statistical study on solar activities. The results show that active longitude band and main hemisphere of solar activity are very important information for the short term prediction of solar activity.
