<b>Session description</b><br>
A18 - Dependable, Long-Term Geomagnetic Indices and Modern,
Index-Based Services: 70th Anniversary Of the Kp Index<br>
<br>
70 year ago, in 1949, Julius Bartels introduced the geomagnetic Kp
index. This symposium is dedicated to the production, prediction and
application of geomagnetic indices.<br>
These indices, derived from geomagnetic observations, quantify
phenomena like the energy transfer from the solar wind or the
strength of the ring current. They are used as space weather
indicators and as input for empirical models of the space
environment. Due to their long-term stability they can be used to
quantify space climate. Next to the established IAGA-endorsed
geomagnetic indices there also exist researcher-driven indices to
address specific scientific questions.<br>
