Sunspots appear pretty much all the time, but there are more of them during a solar maximum.
Solar Maximum
Basically, a maximum of sunspots.
Sunspots are most common during a sunspot (solar magnetic) maximum, this occurs periodically, on an 11 year cycle.
The minimum and maximum refers to the number of sunspots.
The minimum and maximum refers to the number of sunspots.
A solar maximum is when the number of sunspots increase. These sunspots are thought to be caused by interplay between the sun's plasma and its magnetic field. The next solar maximum will be on 2024.
The Sun goes through about an 11-year cycle. During that period, the number of sunspots increases to a maximum and then decreases to a minimum. Right now, the Sun is at an extended minimum activity level; there have been very few sunspots for about 18 months or so. During the last solar maximum, there were usually dozens of very large sunspots on the face of the Sun; now, there are usually no sunspots at all, and when they do appear, they are very small and short-lived. High solar activity levels are associated with solar flares and "coronal mass ejections" that can cause auroras. Satellites and electronics are fairly sensitive to CMEs, and one of the current worries is that if a really intense solar flare and CME were to be pointed at the Earth, it could cause massive disruptions of our electronic communications systems and computers.
Noone knows for sure how many there are. Currently, it is in a solar maximum which is a stage after a solar flare which is the biggest explosion that can occur in space, During a solar maximum sunspots develop. so the numbers keep growing
Sunspots
Solar maximum or solar max is a normal period of greatest solar activity in the 11 year solar cycle of the Sun. During solar maximum, large numbers of sunspots appear and the sun's irradiance output grows by about 0.1%.[1] The increased energy output of solar maxima can impact global climate and recent studies have shown some correlation with regional weather patterns.At solar maximum, the Sun's magnetic field lines are the most distorted due to the magnetic field on the solar equator rotating at a slightly faster pace than at the solar poles. The solar cycle takes an average of about 11 years to go from one solar maximum to the next, with an observed variation in duration of 9 to 14 years for any given solar cycle.Large solar flares often occur during a maximum. For example, the Solar storm of 1859 struck the Earth with such intensity that the northern lights could be seen as far south as Rome, approximately 42° north of the equator.
There is a solar phenomenon believed to be affected by an increase in sunspots. Most solar flares are believed to be linked to an increase in sunspots.
Yes. There is a cycle about 11 years long from the "Solar Minimum" to the "Solar Maximum" to the "Solar Minimum" again. During the minimums, there are few sunspots and not many big flares and eruptions. In 2008, for example, there were 300 days with ZERO sunspots. Today (January 28, 2009) the sunspot number is 11, but for the last week it has been 0. In 5 years or so, we expect the Sun to be very speckled, with sunspot numbers of 300 or more.
