The official planetary K p-index is derived by calculating a weighted average of K-indices from a network of 13 geomagnetic observatories at mid-latitude locations.Since these observatories do not report their data in real-time, various operations centers around the globe estimate the index based on data available from their local network of observatories.
While most of this week’s disturbances are expected to have little to no impact, there is a chance that the expected storm could reach a level of 3 out of 5 on the geomagnetic storm severity scale.
The 2003 Halloween solar storms had a peak Dst index of −383 nT, although a second storm on 20 November 2003 reached −422 nT while not reaching G5-class. [16] [17] The March 1989 geomagnetic storm had a peak Dst index of −589 nT, [18] while the May 1921 geomagnetic storm has been estimated to have had a peak Dst index of −907 ± 132 nT.
