BOULDER–Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun’s impact on Earth over the course of the 11-… ...

The new 11-year cycle, called Solar Cycle 24, is expected to build gradually, with the number of sunspots and solar storms reaching a maximum by 2011 or 2012, though devastating storms can occur ...

Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar flares, and coronal mass ejections. This peak is anticipated around mid to ...

For the study, the researchers examined drawings of sunspots made by Johannes Kepler in 1607 along with past notes to ascertain which solar cycle these sunspots belonged to, which could help ...

NOAA ISES Solar Cycle Sunspot Number Progression: Solar cycles 24 (left hump) and 25 (right hump) are clearly visible. Black dots show individual monthly sunspot values, whilst the purple line ...

The sun’s magnetic activity causes auroras, and the relationship between solar flares and auroras reveals an 11-year cycle; we’re experiencing a particularly busy one right now.

The agencies that track sunspot activity say we’re now in peak solar activity, which has a big impact on the amount and southward extent of the Northern Lights. On Oct. 15, 2024 NOAA, NASA and ...

From this graph, we can see that Solar Cycle 25 (from 2019 to present) has already exceeded the size of Solar Cycle 24. The largest individual sunspot month of the cycle so far, August 2024, had a ...

Even though the sun's current solar cycle hasn't reached its peak yet, scientists have seen signs that the next 11-year solar cycle is already getting ready for its time to shine.

Currently, the average number of sunspots during this solar cycle, Solar Cycle 25, is around 230. If it continues this way, it would eclipse every month since Sept. 2001, which occurred during the ...

Drawings he made of a sunspot group in 1607, a new study reveals, show the "tail-end of the solar cycle" with instrumentation before the telescope was more widely available in the early 17th century.

Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar flares, and coronal mass ejections. This peak is anticipated around mid to ...
