Low Solar Activity Likely 20-22 Oct

Lull in Sunspot Activity 20 Oct, 2023
Low Solar Activity Likely 20-22 Oct
published: Tuesday, October 24, 2023 19:23 UTC

It is not uncommon to experience less sunspots and decreases in solar activity as a solar cycle progresses. Despite this current lull, the solar cycle continues to progress towards maximum https://www.swpc.noaa.gov/products/solar-cycle-progression  NSO/GONG Helioseismology is an important tool to help SWPC forecasters garner hints of potential active region development beyond the solar limb. However, caution is always used with these observations because of capability limitations and since sunspot groups can form quite quickly.
