The start of solar cycle 25 was declared by SIDC on September 15, 2020 as being in December 2019. [9] This makes cycle 24 the only "11-year solar cycle" to have lasted precisely 11 years. Details of cycles 1 to 25

Over a period of 11 years, the sun goes through a cycle of low to high activity and back to low — which are called solar cycles. We're currently in a solar cycle that started in 2019, so solar ...

The sun will reach solar maximum, or a peak in activity across its 11-year cycle, about a year sooner than originally predicted. Auroras, solar flares and space weather are all expected to increase.
Recognition of the lunar cycle as a (lunar) month, and the solar cycle as the (solar) year, the basis for calendars. Observation of non-fixed or "wandering" objects in the night sky: the five classical planets; shooting stars and meteor showers; bolides; comets; auroras; zodiacal light. Solar and lunar eclipses. Planetary conjunctions.
Solar cycles typically last 11 years and during that time, the north and south magnetic poles flip. It looks a lot like a heartbeat when graphed out. We're currently in Cycle 24.
