2. I could increase REM percent by extending total sleep time past 9 hours or waking for 5 minutes at approximately 4.5 hours after sleep onset. Short wakings of 5-10 minutes, particularly one additional waking approximately 6.5 hours after sleep onset, dramatically increased REM percent. It turns out that waking is not necessarily a bad thing, at least when intentional.
The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle. Near the minimum of the solar cycle, it is rare to see sunspots on the Sun, and the spots that do appear are very small and short-lived.
The Solar Cycle. The sunspot cycle, a regular increase and decrease in the number of spots on the sun, is an 11-year cycle where there's an increase in the average number of sunspots to a sunspot maximum and then a decrease to a sunspot minimum before rising to a maximum again.his cycle is related to the magnetic polarities of sunspot groups. A group of sunspots moves with the sun's rotation, and the sunspots in front, like a train's engine, are the preceding members, while those moving behind them, like the railcars, are the following members.
