Northern lights activity to increase during solar maximum. Electromagnetic activity is increasing as the sun continues to reach the height of its 11-year solar cycle, which NASA said is expected ...
Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle. The sun is now in its solar maximum, meaning more aurora activity Skip to main content
The sun will reach solar maximum, or a peak in activity across its 11-year cycle, about a year sooner than originally predicted. Auroras, solar flares and space weather are all expected to increase.
The level of solar activity beginning in the 1940s is exceptional – the last period of similar magnitude occurred around 9,000 years ago (during the warm Boreal period). [ 11 ] [ 12 ] [ 13 ] The Sun was at a similarly high level of magnetic activity for only ~10% of the past 11,400 years.
Polar night is a phenomenon that occurs in the northernmost and southernmost regions of Earth when the Sun remains below the horizon for more than 24 hours. This only occurs inside the polar circles. [1] The opposite phenomenon, polar day or midnight sun, occurs when the Sun remains above the horizon for more than 24 hours.
A solar flare is a sudden flash of brightness observed over the Sun's surface or the solar limb, which is interpreted as an energy release of up to 6 × 10 25 joules (about a sixth of the total Sun's energy output each second or 160 billion megatons of TNT equivalent, over 25,000 times more energy than released from the impact of Comet ...
‘Significant change’ in Sun’s activity may come as good news for sky watchers ahead of next year’s solar eclipse
The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25.
