9312424 Sturrock This is a research project to study periodic modulation of solar flare activity and the distribution of major flares on the solar surface. Past studies have indicated that all observed periodicities in sunspot activity are subharmonics of a fundamental 25.5 day periodicity. If this assertion is proven, then considerable insight into the nature of the solar interior will be gained. The study on distribution of solar flares is based on the observation that major flares tend to be concentrated in "hot spots" which typically exhibit rigid rotation rather than the expected differential rotation characteristic of the solar surface. The investigators will analyze sunspot data to further elucidate the behavior of these hot spots. Sunspot data to be used in the study include observations made by the Greenwich Observatory and the Kitt Peak National Observatory. ***

小行星9312424 这是一个研究太阳耀斑活动的周期性调制和太阳表面主要耀斑分布的研究项目。 过去的研究表明，所有观测到的太阳黑子活动周期都是25.5天基本周期的次谐波。 如果这一断言得到证实，那么将获得对太阳内部性质的相当深入的了解。 对太阳耀斑分布的研究是基于这样的观察，即主要耀斑往往集中在“热点”，这些热点通常表现出刚性旋转，而不是太阳表面预期的差异旋转特征。 研究人员将分析太阳黑子数据，以进一步阐明这些热点的行为。 研究中使用的太阳黑子数据包括格林威治天文台和基特峰国家天文台的观测数据。 ***
