Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [ 2 ]
The sun's activity is expected to continue to increase until it reaches peak activity levels, which scientists call solar maximum. "Current predictions suggest solar maximum will occur in the ...
Solar activity was elevated over the past weekend, according to the SWPC, causing solar flares and coronal mass ejections. Those CMEs are expected to arrive starting today and continue through Aug. 1.
The sun emits the largest solar flare of this 11-year cycle, as imaged by NASA's Solar Dynamics Observatory on October 3. ... The current solar maximum likely began in early 2023, ... The Today Show.
Reconstruction of solar activity over 11,400 years. Sunspot numbers over the past 11,400 years have been reconstructed using carbon-14 and beryllium-10 isotope ratios. [10] 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).
Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle. ... News. Science & Tech. Shopping. Sports. Weather ...
An example is the Meeus smoothing formula, [7] with related solar cycles characteristics available in this STCE news item. [ 8 ] The start of solar cycle 25 was declared by SIDC on September 15, 2020 as being in December 2019. [ 9 ]
An incoming geomagnetic storm is expected to hit the Earth today, ... The sun is becoming more active as it nears the peak of its current 11-year solar cycle, which ... solar activity slows down ...
