【摘要】：相对第22太阳活动周,第23太阳活动周太阳活动和空间天气的观测,无论是观测内容,还是观测精度以及观测的连续性等方面都有全面的提升,这为我们系统地统计分析第23周的太阳活动及相关的现象提供了很好的条件。依据NOAA提供的1996-2008年期间每一个活动区的数据,本文统计分析了1996-2008年期间活动区的面积。在统计分析不同面积的活动区的数量,出现的时间,经度和纬度时,采用的是一个活动区在可见日面出现期间的最大面积。经过统计分析,我们得到以下结论：1.活动区面积较小的占绝大多数,面积在1000μh以上的仅占活动区总数的约1%。2.第23周的一个显著特征是太阳活动水平上升非常快,并且在下降段的很长时间内太阳活动依然非常强。3.研究显示活动区面积不是决定活动区是否为超级活动区的一个关键参量。4.面积超过1000μh的活动区的卡林顿经度分布具有漂移特征。第22周的X级耀斑,美国大气海洋管理局(NOAA)并不提供每一个软X射线耀斑在1-8A波段的高时间分辨率的流量值,也不提供耀斑在在1-8A波段流量的积分值。但是,在第23周NOAA提供了每一个耀斑在1-8A波段流量的积分值,我们用FSXR表示一个耀斑在1-8A波段流量的积分值,依据每一个耀斑的FSXR值和对应的活动区信息,我们可以得到一个活动区产生的所有耀斑在1-8A波段流量的积分值的总和(用ergs.cm-2表示)。通过对1996-2008年的活动区耀斑的流量积分的统计分析,我们得到统计分析的结果如下：1.随着FAR的增大,相应的活动区数量急剧下降,活动区的数量随FAR变化的关系式为：N(FAR)=2026e-22.23FAR。2.一个活动区产生的所有耀斑的软X射线流量积分值的和(FAR)与活动区的最大面积具有很好的相关性,而一个活动区产生的一次耀斑的软X射线的流量值(FSXR)与耀斑爆发时的活动区面积没有相关性。耀斑爆发时,绝大多数能量是在可见光波段,软X射线波段的光子占耀斑光子辐射总能量很少的一部分,尽管如此,耀斑在1-8A波段流量的积分值大的耀斑,其耀斑的总能量也大,因此,我们采用南北半球活动区产生的耀斑在软X射线波段流量的积分值分析了1997-2008年期间太阳南北半球耀斑释放能量的不对称性,分析得到的结果如下：在1997-2000年期间,北半球耀斑爆发过程释放的能量比南半球多,而在1997-2008年期间,南半球耀斑释放的能量超过北半球。超级活动区与耀斑的关系有非常多的研究工作,但是,超级活动区与太阳质子事件和磁暴关系的研究工作非常少。本文从每一个活动区耀斑释放能量的角度对12个超级活动区进行了排序,然后简要分析了第23周超级活动区的太阳质子事件效应和地磁暴效应,得到以下结果：1.依据每一个超级活动区产生的所有耀斑在1-8A波段流量积分值的总和对第23太阳活动周的12个超级活动区的强弱进行排序,12个超级活动区从强到弱的顺序依次为：10486、10808、10720、9415、9393、10930、9077、10484、10488、10069、8307、8100。2.超级活动区不仅会产生很多强烈的耀斑事件,而且还会产生很多GLE事件和一定数量的特大磁暴事件.
[Abstract]:Compared with the twenty-second solar activity weeks, the observation of solar activity and space weather in the twenty-third solar activity week, whether it is the content of observation, the accuracy of observation and the continuity of observation, provides a good condition for our systematic statistical analysis of the solar activity and related phenomena for twenty-third weeks. According to NOAA, 19 The area of the active area for the period of 1996-2008 years was statistically analyzed in each area of the 96-2008 year period. In the statistical analysis of the number of active areas in different areas, the occurrence time, the longitude and latitude, the largest area of the active area was used during the visible day. After statistical analysis, we got the following conclusions 1. the vast majority of the area of the active area is small, and the area in the area of more than 1000 mu h accounts for about 1%.2. twenty-third weeks in the total number of active areas. A significant feature of the solar activity is that the solar activity is rising very quickly, and the solar activity is still very strong in the decline segment for a long time. The active area of the area is not determined as to whether the area of the active area is super. The Carrington longitude distribution of a active area with a key parameter of.4. area over 1000 mu h has a drift characteristic. The X flare for twenty-second weeks, the American atmospheric Oceanographic Administration (NOAA) does not provide the high time resolution of each soft X ray flare at the high time resolution of the 1-8A band, nor does it provide the integral value of the flare in the 1-8A band. However, at the twenty-third week NOAA, the integral value of each flare in the 1-8A band flow is provided. We use FSXR to express the integral value of a flare in the 1-8A band. According to the FSXR value of each flare and the corresponding active area information, we can get the sum of the integral values of the flare of a flare in the 1-8A band (E). According to the statistical analysis of the flow integral of the flare of the 1996-2008 year active area, we get the results of the statistical analysis as follows: 1. with the increase of FAR, the number of the corresponding active area drops sharply, and the relation of the number of active area with FAR is all the flares produced by N (FAR) = 2026e-22.23FAR.2.. The sum of the soft X ray flow integral value and (FAR) have a good correlation with the maximum area of the active area, while the flow value of the soft X ray of a flare produced by an active area (FSXR) is not related to the area of the active area when the flare erupts. When the flare erupts, the vast majority of the energy is in the visible light band, and the photon in the soft X ray band is occupied. The total energy of the spot photon radiation is very small, although the flare has a large solar flare in the 1-8A band flow, and the total energy of the flare is large. Therefore, we use the integral of the flare produced by the northern hemisphere active region in the soft X - ray band flow to analyze the misalignment of the solar flare releasing energy during the 1997-2008 year period. The results of the analysis are as follows: during the 1997-2000 years, the solar flare released during the northern hemisphere was more energy than the southern hemisphere, and during the 1997-2008 year the energy released by the southern hemisphere flare exceeded the northern hemisphere. The relationship between the superactive area and the flare has a lot of research work, but the superactivity zone and the solar proton events and magnetism The study of violent relationship is very small. This paper sorted 12 super active regions from the angle of flare release energy from each active area, and then briefly analyzed the solar proton event effect and geomagnetic storm effect in the twenty-third week super activity area, and obtained the following results: 1. according to each of the flares produced in each super activity area in 1-8A The sum of the band flow integral values of the 12 superactive regions of the twenty-third solar activity week is sorted. The order of the 12 superactive regions from strong to weak is the following: the 1048610808107209415939310930907710484104881006983078100.2. superactivity area not only produces a lot of strong flare events, but also produces very strong flare events. Multiple GLE events and a certain number of large magnetic storms.
