Long-Term Cosmic Ray Variability and the CME-Index
Figure 1
(a) Time profiles, starting from the top, of the sunspot number , CME-index , and the cosmic ray variations for the period of 1996–2011. The period of extended minimum is noted between the dashed lines for all the examined parameters. (b) Time profiles, starting from the top, of the interplanetary magnetic field (IMF), the heliospheric current sheet tilt (HCS), and the cosmic ray variations for the period of 1996–2011. The period of extended minimum is noted between the vertical dashed lines.
