This activity cycle is comparable to the solar cycle of the Sun.

He was the first scientist to discover activity cycles, similar to the solar 11-year sunspot cycle, in other stars.

They have also evolved a matinal daily activity cycle, flying before sunrise.

Its surface has a measured activity cycle of 16.6 years, compared to 11 years on our Sun.

It may also have a secondary activity cycle of 9.6 years.

Their daily activity cycles are controlled by environmental light levels.

Our sun has a solar activity cycle of about 11 years.

The activity cycle for this star is 11.1 years in length.

The sun by comparison has a 11 year magnetic activity cycle.

If it gets another two or three years, just a little bit longer, then you approach the time scales of the magnetic activity cycles.
