We have studied long-term variations of galactic cosmic-ray (GCR) intensity in relation to the
sunspot number (SSN) during the most recent solar cycles. This study analyses the time lag …

Solar magnetic activity drives the dominant 11-year cyclic variability of different space
environmental indices, but they can be delayed with respect to the original variations due to …

Cosmic rays measured through neutron monitors on Earth's surface have a strong
correlation with the number of sunspots on the solar photosphere. Other indices that affect …

Abstract Galactic Cosmic Rays (GCRs) are charged particles, originating from galactic
and/or extra-galactic Supernova Remnants (SNR), that continuously permeate the …

In the present article, we analyze long-term changes in the intensity of galactic cosmic rays
(GCRs) in different polarity epochs of the solar magnetic cycles from 1959 to 2014. Our …

We investigated correlations between cosmic-ray intensity and 14 solar and interplanetary
parameters, which were classified into four cases. We used the modulation of cosmic-ray …

After a prolonged and deep solar minimum at the end of Cycle 23, the current Solar Cycle 24
is one of the lowest cycles. These two periods of deep minimum and mini-maximum are …

It has been suggested that the shortage in the number of spots on the surface of the Sun
between 1790 and 1830, known as the Dalton minimum, contained an extra cycle that was …

Electrons in the Earth's radiation belts can be categorized into three populations:
precipitating, quasi‐trapped, and trapped. We use data from the Detection of Electro …

Sunspot observations since 1610 AD show that the solar magnetic activity displays long-
term changes, from Maunder Minimum-like low-activity states to Modern Maximum-like high …
