The time during the solar cycle when the Sun is in line with its magnetic poles as it has completed an 180 degree reversal, causing less solar activity
The month(s) during the Solar Cycle when the twelve-month mean (average) of monthly average sunspot numbers reaches a minimum. The most recent minimum occurred in September 1986. ( go to first use in the text)
The time at which the Sun reaches its lowest point in solar activity as defined by the 12-month smoothed value of the sunspot number.
The lowest level in solar activity. It occurs between solar maxima.
The time at which the sun is least active.
The month(s) during the solar cycle when the number sunspots is lowest. The most recent minimum occurred in 1996.
The month(s) during the solar cycle when the 12-month mean of monthly average sunspot numbers reaches a minimum. The most recent minimum occurred in November 1996 (??).
A solar minimum is a low level in solar activity (like flares, prominences, sunspots, soronal holes, etc.), and occurs between consecutive solar maxima.
A period of decreased solar activity when the number of sunspots reaches a minimum in the 11-year solar cycle.
See sunspot minimum.
The beginning and the end of a sunspot cycle when only a few sunspots are usually observed, and the output of particles and radiation is normal.
Solar minimum is the period of least solar activity in the solar cycle of the sun. During this time sunspot and solar flare activity diminishes, and often does not occur for days at a time. The date of the minimum is described by a smoothed average over 12 months of sunspot activity, so identifying the date of the solar minimum usually can only happen 6 months after the minimum takes place.
