01.19.12 - After a two month respite from Earth-directed solar events, the Sun sends an M3.2 class flare and CME our way.
On Thursday, Jan. 12, 2012, Dr. Holly Gilbert will discuss the amazing strides scientists have made in understanding the inner workings of our sun over the last 50 years. The lecture will start promptly at 7 p.m., and registration in advance is required.
12.02.11 - NASA's Heliophysics Division's workshop for the Fall 2011 AGU meeting: "Getting Ready for Solar Max: Separating Fact from Fiction on Impacts of Space Weather".
11.04.11 - The sun sent out two different kinds of solar activity on November 3, 2011 in different directions: an X.19 solar flare and a particularly bright CME.
While our sun is usually a kind and beneficial space neighbor, we sometimes feel its "moodiness" here on Earth. On Oct. 27, NASA expert Dr. Jonathan Cirtain answered your questions about the sun.

10.25.11 - A coronal mass ejection (CME) shot off the sun late in the evening of October 21 and hit Earth on October 24 at about 2 PM ET causing red aurora in the U.S.
10.19.11 - Solar Week provides a week-long series of web-based educational activities for classrooms about our magnetic variable star, the sun, and its interactions with Earth and the solar system.
10.04.11 - On October 2, 2011, an exceptionally bright comet headed toward the sun and disintegrated; moments later a large coronal mass ejection (CME) blew off the other side of the sun.
09.22.11 - Our increasingly active Sun produced a large CME yesterday evening and an X1.4 class flare this morning. This increased solar activity is a normal byproduct as the sun approaches solar max.
09.20.11 - The sun let loose with at least six coronal mass ejections (CMEs) from 7 PM ET on September 18, 2011 until 1 PM on September 19. One may impact Earth and spark aurora tomorrow.
09.22.11 - This view of the aurora from Earth orbit was taken from the International Space Station as it crossed over the southern Indian Ocean on September 17, 2011.
09.12.11 - After last week's flurry of strong flares from sunspot 1283, solar activity is subsiding as this sunspot rotates over the sun's western limb. Aurora from last week's solar activity will be dancing in the sky for the next several day.
09.08.11 - The first of what will likely be several CME hits occurred this morning sparking a strong geomagnetic storm. Additional hits will occur over the weekend.
09.07.11 - Sunspot 1283 erupted with another flare yesterday that peaked at 6:20 PM ET. This was an X2.1 class flare, some four times stronger than the earlier flare.
09.06.11 - At 9:35 PM ET on Labor Day, the sun emitted an Earth-directed M5.3 class flare as measured by the GOES satellite.
