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.
An example of a recent sunspot cycle spans the years from the solar min in 1986, when 13 sunspots were seen, through the solar max in 1989 when more than 157 sunspots appeared, on to the next solar min in 1996 (ten years after the 1986 solar min) when the sunspot count had fallen back down to fewer than 9.his solar cycle is, on average, about 22 years long-twice the duration of the sunspot cycle. Some scientists believe there is evidence for other, longer-period variations in the sunspot and solar cycles.
