Report for 2/24/12

This week was pretty exciting! On Tuesday, the Solar Dynamics Observatory (SDO) captured stunning shots of the Lunar Transit (see images below). On Thursday, a "solar tsunami" erupted from the Sun, which released a burst of plasma into space at an incredible speed of approximately 250 km/s. A filament erupted this morning causing a coronal mass ejection (CME) to be hurled into space, but it is not headed for Earth and should not affect us.

Report for 2/10/12

The Sun started the week off strong with a powerful coronal mass ejection (CME) and M1-class solar flare on Monday. Mid-week, a moderate solar wind stream flowed to Earth leading NOAA forecasters to predict a 40% chance of a geomagnetic storms in the higher latitudes. No major storm activity occurred, but sky watchers around the Arctic Circle were treated to vibrant auroras.

Last night, a filament on the Sun's northeastern limb exploded, causing a CME that is currently heading toward Venus. Although the blast is not headed our way, a new sunspot located near the blast site may be a potential source of solar activity in the upcoming week.
