Sunspots are regions of high physical and magnetic turbulence on the Sun. They increase and decrease in number during an 11-year solar sunspot cycle, but variations within the cycle mean it isn't always just a smooth up and down graph.
From the sunspots large amounts of radiation and matter can be thrown around and some of the radiation can cause electrical and magnetic disturbances in the upper atmosphere or even on the Earth itself. During high sunspot activity the general level of solar surface and coronal activity is also high, with more flares and prominences which also areas of great disturbances.
Flares are huge disturbances on the Sun which can throw out massive amounts of radiation and mass in what are known as CME's, or Coronal Mass Ejections, and they can have a big effect on Earth.
Large disturbances on Earth from solar storms are called geomagnetic storms can knock out entire electrical networks as has happened in Canada and the northern states of the USA before.
For the last two years the Sun has been unusually quiet, meaning very few sunspots have been seen and therefore fewer magnetic disturbances have happened, including the disappearance of the Northern Lights for almost the entire period but there are a few sunspots visible now and an occasional aurora has been seen since last December.

What do some scientists say about the relationship between sunspots and the Earth's temperature?
According to current theory, sunspots occur in pairs as magnetic disturbances in the convective plasma near the Sun's surface. Magnetic field lines emerge from one sunspot and re-enter at the other spot. Also, there are more sunspots during periods of increased magnetic activity. At that time more highly charged particles are emitted from the solar surface, and the Sun emits more UV and visible radiation. Direct measurements are uncertain.
Is there a relationship between radiant energy and electrical energy?
there is a relationship they produce temperature.
What is the relationship between voltage and wavelength in an electrical system?
In an electrical system, the relationship between voltage and wavelength is indirect. As voltage increases, the wavelength of the electrical signal decreases. This is because higher voltage leads to higher frequency, which in turn results in shorter wavelengths.
What is the relationship between resistance and temperature in electrical circuits?
In electrical circuits, the resistance of a material typically increases as its temperature rises. This relationship is known as temperature coefficient of resistance.
What is the relationship between electrical frequency and magnetic field speed for an ac machine?
In an AC machine, the electrical frequency of the input power supply determines the rotational speed of the magnetic field, which interacts with the conductors in the machine to produce electrical power. The relationship between electrical frequency and magnetic field speed is directly proportional – an increase in electrical frequency results in a corresponding increase in the speed of the rotating magnetic field.
What is the relationship between electrical energy and kinetic energy?
It ends up with energy
What is the relationship between kinetic and electrical energy and a generator?
It ends up with energy
What are the relationships between electrical energy and nuclear energy?
Nuclear energy is used to produce electrical energy, but there is no direct relationship
What is the relationship between voltage and temperature in electrical circuits?
In electrical circuits, the relationship between voltage and temperature is that an increase in temperature can lead to an increase in voltage. This is because temperature affects the resistance of the materials in the circuit, which in turn can impact the voltage.
What happens when disturbances in opposite direction meet along the medium?
When disturbances in opposite directions meet along a medium, they can either cancel each other out, resulting in destructive interference, or they can combine to create a larger disturbance, resulting in constructive interference. The outcome depends on the phase relationship between the two disturbances at the point of interaction.
