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 rotational period of an object in the solar system is the amount of time it takes for the object to complete one turn, or rotate on its axis. In addition to rotational movement, the bodies in our solar system also move around, or orbit, other bodies.Planets orbit the Sun while moons orbit around planets.The amount of time required for a planet or moon to complete one orbit around another body is called an orbital period. On Earth, we call this orbital period a year. Our year is 365.256 days.On Mars it takes 686.98 days (Earth days, that is) to complete one orbit about the Sun--that's a long time to wait between birthdays!lanets orbit the Sun while moons orbit around planets.
