The solar cycle is the nearly periodic 11-year change in the Sun’s activity that has been observed for centuries. This includes changes in the levels of solar radiation and ejection of solar material as well as changes in the number and size of sunspots, flares, and other manifestations. According to new measurements, the solar magnetic activity cycle has already reached its minimum, some 1.5 years before the expected time. Scientists believe there will hardly have strong magnetic storms…
The report published on December 18, 2017 on the website of the Laboratory of X-ray Solar Astronomy of the PN Lebedev Physical Institute reads:
‘Space weather in the vicinity of our planet is increasingly losing its connection with the Sun (solar flares), which has almost reached the minimum of its present cycle about 1.5 years ahead of schedule. The main factor of space weather has now become solar wind, the stream of plasma produced due to the continuous expiration of the upper layers of the solar atmosphere into the surrounding space. At least until our star wakes up from its dream.
As of Dec. 18th, the sun has been without spots for 100 days in 2017. The last time the sun crossed this threshold was in 2009 (260 spotless days) when the solar cycle was just beginning to rebound from a century-class Solar Minimum. Now, we have reached solar minimum. In 2018 we can expect at least twice as many spotless days (200+) as blank suns once again become the norm:
Scientists say that the impact of solar wind on the Earth is normally very weak and cannot cause strong magnetic storms. And unlike solar flares, solar winds can be predicted much better and faster.
Well, let’s say that the INTENSE G1 solar storm that hit Earth two days ago was just another space weather anomaly.
