A Whole Lot Happening on the Sun – In Many Types of Light

The sun has been really active lately. SDO gives us an amazing view of this activity in many different wavelengths of light. This also shows us the sun’s atmosphere in many temperatures ranging from ~4500 Kelvin or 7600 degrees Fahrenheit […]

CME may impact the Earth and Spitzer 5/19/2013

16:16 UT – NASA SWRC simulations indicate that the leading edge of the CME will reach Spitzer at 2:56 UT 5/19/2013 and Earth at 11:59 UT 5/19/2013 (+- 7 hrs). Roughly estimated expected maximum Kp index is 5-6 (minor to moderate). […]
