It is in the midst of an unusual sunspot minimum, lasting far longer and with a higher percentage of spotless days than normal; since May 2008.
It is measurably dimming; its output has dropped 0.02% at visible wavelengths and 6% at EUV wavelengths in comparison with the levels at the last solar minimum.[130]
Over the last two decades, the solar wind's speed has dropped by 3%, its temperature by 13%, and its density by 20%.[131]
Its magnetic field is at less than half strength compared to the minimum of 22 years ago. The entire heliosphere, which fills the Solar System, has shrunk as a result, thereby increasing the level of cosmic radiation striking the Earth and its atmosphere.
Lori Losinski on 20 Mar 12Mrs. Meacham's website has a fantastic section on reader's workshop with units that focus on: front loading, fix-up strategies, connection, visualizing, questioning, determining importance, inferring, and synthesizing. Each unit has a link that takes you to the materials she uses while teaching each mini lesson. I especially like that you can print out all of the material and use it in your own classroom.
