COSMIC RAYS ARE NEARING A SPACE AGE HIGH: Ten years ago, NASA reported a “perfect storm of cosmic rays.” During the year 2009, radiation peppering Earth from deep space reached a 50-year high, registering levels never before seen during the Space Age.
It’s about to happen again.
Ground-based neutron monitors and high-altitude cosmic ray balloons are registering a new increase in cosmic rays. The Oulu neutron monitor in Finland, which has been making measurements since 1964, reports levels in April 2019 only percentage points below the Space Age maximum of 2009:

What’s going on? The answer is “Solar Minimum.” During the low phase of the 11-year solar cycle, the sun’s magnetic field and solar wind weaken. Cosmic rays find it easier to penetrate the inner solar system. In 2009, the sun experienced the deepest solar minimum in a century. Cosmic rays reaching Earth naturally surged.
Ten years later, solar minimum is back with renewed weakening of the sun’s magnetic field and the solar wind. Again, it’s a “perfect storm.” A panel of experts led by NOAA and NASA recently predicted that the current minimum would reach a nadir in late 2019 or 2020, likely matching the record-setting minimum of 2009. If they’re right, cosmic rays will continue to increase, with a new record possible in the near future.

Do more cosmic rays result in more clouds? How can this be measured? Ideas?
