Are we in a solar grand minimum? We've seen this before, but now predictions are for an extremely weak solar cycle ahead.

Today is the summer solstice in the northern hemisphere. The sun has been without a single observable sunspot now for over a month – 33 days according to NOAA and SIDC data. Spaceweather.com says:

"This is a sign of Solar Minimum, a phase of the solar cycle that brings extra cosmic rays, long-lasting holes in the sun's atmosphere, and a possible surplus of noctilucent clouds. "

There's been sightings of the electric blue noctilucent clouds as far south as Joshua Tree, near Los Angeles, and many many other locations. But one of the most interesting things is due to the fact that the Sun's magnetic field has weakened, more cosmic rays are now bombarding Earth and some airline flights are seeing doses of radiation up to 73 times that which we'd see at ground level.
