Default A spotless sun

Incredible image shows solar activity at its quietest in 100 years - and some say it could trigger a mini ice age

For the second time this month, the sun has gone into 'cue ball' mode
We've had smallest number of sunspots in this cycle since Cycle 14
This cycle reached its maximum solar activity in February of 1906
Low solar activity can lead to extended periods of cooling, researchers say

The sun is in the currently in its quietest period for more than a
century. For the second time this month, the sun has gone into 'cue
ball' mode, with images from Nasa showing no large visible sunspots
on its surface

Instead of counting the sun spots, isn't it easier to measure the total radiation (heat) recieved on earth on a m2/km2 scale ? I am sure some institutions are measuring them. Would like a link please

Quote:
TSI varies in phase with the solar magnetic activity cycle[46] with an amplitude of about 0.1% around an average value of about 1361.5 W/m2[47] (the "solar constant"). Variations about the average of up to −0.3% are caused by large sunspot groups and of +0.05% by large faculae and the bright network on a 7-10-day timescale[48] (see TSI variation graphics).[49] Satellite-era TSI variations show small but detectable trends.[50][51]
Its the SIZE of the sunspots that indicate the magnetic disturbance effecting the earth. See the 'Weak Sun' thread.

Oric does not have access to the internet? Should we have to resort to posting links to wiki?

Our temperatures recently haven't been record breaking, but it is late June which puts us well into the Florida rainy season. This means that if it's not clouding up to rain by the afternoon we'll be in the mid-nineties with the heat index typically between 100-110.

Not record breaking, but it does make for a torrid afternoon of working outside!
