The period in the roughly 11-year cycle of solar activity when the maximum number of sunspots is present
The time during the solar cycle when the Sun is out of line with its magnetic poles and turning, causing more solar activity
a maximum level of solar activity that runs in 11-year cycles; the year 2000 was the most recent period of solar maximum
The time at which the Sun reaches its highest activity as defined by the 12-month smoothed value of the sunspot number.
The time at which the sun is most active. Activity is determined by the number of and area covered by sunspots.
The month(s) during the solar cycle when the number of sunspots reaches a maximum. The most recent solar maximum occurred in mid-2000.
The month(s) during the solar cycle when the 12-month mean of monthly average sunspot numbers reaches a maximum. The most recent solar maximum occurred in July 1989.
A solar maximum is the highest level in solar activity (like flares, prominences, sunspots, soronal holes, etc.), and occurs between consecutive solar minima.
the peak of the 11-year solar activity cycle. The last one occurred in 1989-90, and the next one is expected in 2000-01. It is a time in which we are more vulnerable to "space weather."
A period of increased solar activity when the number of sunspots reaches a maximum in the 11-year solar cycle.
The month(s) during the solar cycle when the number of sunspots reaches a maximum. The next solar maximum will occur in about the year 2000.
The midst of a sunspot cycle when the numbers of sunspots are substantial, and the output of particles and radiation is maximized.
The midpoint in the solar cycle where the amount of sunspot activity and the output of cosmic particles and solar radiation is highest.
Solar maximum or solar max is the period of greatest solar activity in the solar cycle of the sun. During solar maximum, sunspots appear.
