Kp index
The name Kp-Index (“K” for “code”) denotes a planetary code. This index was developed to represent solar particle radiation by its magnetic effect. The symbolic representation takes place in the integer values 0 to 9 in a diagram (English designation: Bartels music or musical diagram ), this shows the quantitative values of the KP index. It allows an orientation on the activity through the length and width of the symbols.
Julius Bartels developed the Kp index as a measure of geomagnetic activity at the Geophysical Institute in Potsdam in 1949 . The Kp index is determined using a standardized procedure from data from 13 worldwide observatories. The Kp index was recognized as an important measure by the International Association of Geomagnetism and Aeronomy (IAGA) in 1967 .
Applications
The Kp index is often used in examinations and observations of terrestrial magnetism and is also an indicator for possible aurora phenomena .
