Nov 12, 2017 · Kp9 = Extreme storm (G5) Magnetometers measure the strength of Earth’s magnetic field to determine the K-index, which is tied to a specific station. The Kp-index is calculated by combining the data from multiple magnetic observatories around the world to determine the global planetary index.

Apr 13, 2023 · The Kp9 or G5 is the highest level on the scale from Kp0 to Kp9 and is an absolutely unique aurora event. Imagine the colorful aurora dancing in the sky in New York, London, Amsterdam, or Colorado national parks.

NOAA uses a five-level system called the G-scale, to indicate the severity of both observed and predicted geomagnetic activity. This scale is used to give a quick indication of the severity of a geomagnetic storm. This scale ranges from G1 to G5, with G1 being the lowest level and G5 being the highest level.

Mar 13, 2021 · In space weather application, Kp is used for the National Oceanic and Atmospheric Administration (NOAA) Geomagnetic Storms or G-scale, ranging from minor (G1) for Kp = 5 to extreme (G5) for Kp = 9 (www.swpc.noaa.gov). It is also one of the parameters distributed by ESA's Space Situational Awareness Program (http://swe.ssa.esa.int/).

Jul 29, 2024 · kp9/g5级地磁风暴让全美人民为之疯狂，掀起全民家门口看极光活动。 好消息是，7月29日-7月31日晚上，大半个美国的追极光活动回归啦！ NOAA太空天气预报中心预测，接下来几天夜晚我们将迎来相对罕见的G3地磁风暴等级，虽然不及G5，但也很少见！

Kp9 (G5) 3月24日，一场强烈的磁暴意外地袭击了地球，达到了G4，产生了南至新墨西哥州的极光。 M1耀斑引发的小型日冕物质抛射预计在当天早些时候发生，但时间和强度出人意料 [ 51 ] 。

On this page you will find an overview of the strongest geomagnetic storms since January 1957 together with links to more information in our archive. Storms are ranked by the Disturbance …

Mar 24, 2025 · The Kp-index is a global auroral activity indicator on a scale from 0 to 9. You can use it as a guide to estimate how active the aurora is and at w...

Feb 22, 2017 · 1、指数——太阳风对地球磁场的影响力度。这个力度的指标是Kp指数，由弱到强用0-9标示。超过Kp5为风暴，即Kp5-Kp9分别对应G1-G5级风暴。指数越高，则越容易看到极光;

美国国家海洋和大气管理局10日发布极强地磁暴（g5级）预警，太阳日冕物质抛射引起的地磁暴对地球的影响将从10日持续至12日。 这是自2003年10月以来，该机构首次发布最高级别G5级地磁暴预警。
