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.
A solar year is the time that it takes the earth to complete one  cycle around the sun. The year is the time taken by earth to  complete a cycle around the sun which takes aâ¦bout 365.25 days.   So, a calendar year is 365 days and 1 quarter. Every Leap Year  (once in 4 years) there is an extra day in February.    A year technically is the time taken for a planet to make one orbit  of the sun. At that rate, an Earth year is shorter than a Mars  year, which is 687 days at a 24 hour day.
