发一下这个数值疯狂的预报
峰值密度100，峰值太阳风速达到800km/s
要是真这样可以冲击G5了都
等明天更新看今天下午这个CME长啥样，会不会叠上或者短时间二连击

On Thursday, May 9, 2024, the NOAA Space Weather Prediction Center issued a Severe (G4) Geomagnetic Storm Watch. At least five earth-directed coronal mass ejections (CMEs) were observed and expected to arrive as early as midday Friday, May 10, 2024, and persist through Sunday, May 12, 2024. Several strong flares have been observed over the past few days and were associated with a large and magnetically complex sunspot cluster (NOAA region 3664), which is 16 times the diameter of Earth.
2024年5月9日，星期四，美国国家海洋和大气管理局空间天气预报中心发布了一个严重(G4)地磁风暴观察。至少有五次指向地球的日冕物质抛射(cme)被观测到，预计最早将于2024年5月10日(周五)中午到达，并持续到2024年5月12日(周日)。在过去的几天里，已经观测到几个强烈的耀斑，它们与一个巨大的、具有复杂磁场的太阳黑子群(NOAA区域3664)有关，它的直径是地球的16倍。

ARE WE ABOUT TO EXPERIENCE A NEW CARRINGTON EVENT? No. AR3664 is indeed a 'Carrington-class' sunspot, but the CMEs it hurled toward Earth over the past few days are not as potent as the monster CME of Sept. 1, 1859. NOAA says we might experience a severe geomagnetic storm when the CMEs arrive this weekend. If geomagnetic storms were hurricanes, 'severe' would be category 4. The Carrington Event was category 5 or greater. So this is no Carrington Event. Even so, category 4 is pretty intense--if it happens. Stay tuned for some great auroras! Aurora alerts: SMS Text

我们要经历新的卡灵顿事件了吗?不。AR3664确实是一个“卡灵顿级”的太阳黑子，但它在过去几天里向地球发射的日冕物质抛射不如1859年9月1日的巨型日冕物质抛射那么强烈。美国国家海洋和大气管理局表示，当cme本周末到达时，我们可能会经历一场严重的地磁风暴。如果把地磁风暴比作飓风，“严重”将是第4级。卡灵顿事件是5级或以上。所以这不是卡灵顿事件。即便如此，如果发生的话，第4级也是相当强烈的。敬请期待精彩的极光!极光警报:短信文本
