Solar slump continues – NOAA: “No indication that we are currently approaching a Maunder-type minimum in solar activity.”


/ 1 day ago April 5, 2019

"Scientists charged with predicting the Sun’s activity for the next 11-year solar cycle say that it’s likely to be weak, much like the current one. The current solar cycle, Cycle 24, is declining and predicted to reach solar minimum – the period when the Sun is least active – late in 2019 or 2020.

 

Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. This is well below the average number of sunspots, which typically ranges from 140 to 220 sunspots per solar cycle."

This video shows the changes of the Sun's photosphere that happen in about one hour. The photosphere is the outer shell of the Sun from where the visible light is radiated. You can observe so-called granules, areas of about 1000 km in diameter, where hot gas from inside the Sun rises to reach the surface of the Sun. As the gas cools down, the gas slides down again into the Sun's interior. The brighter regions indicate hot, rising gas - the darker regions cool and down-welling gas.
