Sentences with phrase «magnetic flux at»

This provides strong support for the hypothesis that solar irradiance variations are caused by changes in the amount and distribution of magnetic flux at the solar surface.

This is in agreement with the recent results of [CITE], but it is in contrast to the earlier analysis of [CITE], and suggests that the source of the irradiance variations is the same for cycles 22 and 23, namely the evolution of the magnetic flux at the solar surface.

The planets may have a spin - orbit coupling effect on the Sun which affects its rotation rate, which would then affect the solar dynamo and sunspot production, and therefore the build up of magnetic flux at the poles, and the length of a solar cycle: if the solar cycle is weaker with less sunspots, it'll take longer for the build up of opposing flux to reach the point when it flips the poles.

Starting in the 1960's at the Mt. Wilson Observatory O.C.
