Are sunspots good for ham radio?
But those solar blemishes are really important to ham radio operators. Sunspots are correlated with solar energy output. That is, the more active and energetic the sun, the more sunspots there will be.

Where is the sunspot cycle now?
Analysis determines we are in Solar Cycle 25 We are now in Solar Cycle 25 with peak sunspot activity expected in 2025, the panel said. Solar Cycle 24 was average in length, at 11 years, and had the 4th-smallest intensity since regular record keeping began with Solar Cycle 1 in 1755.
How many sunspots will occur in 2021?

Are solar flares good for HF propagation?
As the Sun provides the radiation that governs the state of the ionosphere and hence HF radio propagation, any flares or other disturbances are of great importance.
What is MUF in ham radio?
In radio transmission maximum usable frequency (MUF) is the highest radio frequency that can be used for transmission between two points via reflection from the ionosphere (skywave or “skip” propagation) at a specified time, independent of transmitter power.
How many sunspots will there be in 2021?
Are sunspots active now?
Expect #GPS & radio issues now! Sunspots are an indicator of more activity and more magnetic activity on the sun. The more sunspots the sun has, the more active it is.
Is the Sun going into hibernation 2021?
When our star drops out of its latest sunspot activity cycle, the sun is most likely going into hibernation, scientists announced today. Three independent studies of the sun’s insides, surface, and upper atmosphere all predict that the next solar cycle will be significantly delayed—if it happens at all.
