Sunspot 1302 and 1305 have connecting magnetic fields and are erupting in pairs. Each producing a C7.6-Class flare...Watch as SDO captured the events.

DOUBLE ERUPTION: On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA's Solar Dynamics Observatory (SDO) recorded the double blast:

The part of the eruption centered on sunspot 1305 hurled a coronal mass ejection toward Earth. The relatively slow-moving (500 km/s) cloud is expected to reach our planet on Oct. 4th, possibly causing geomagnetic storms when it arrives. High-latitude sky watchers should be alert for auroras.

COMET AND CME: A comet discovered by amateur astronomers on Friday, Sept. 30th, disintegrated in spectacular fashion the very next day when it plunged into the sun. The Solar and Heliospheric Observatory recorded the comet's last hours. The end was punctuated by an unexpected explosion; Watch the movie again. The timing of the CME so soon after the comet dove into the sun suggests a link. But what? There is no known mechanism for comets to trigger solar explosions. Before 2011 most solar physicists would have discounted the events of Oct. 1st as pure coincidence--and pure coincidence is still the most likely explanation. Earlier this year, however, the Solar Dynamics Observatory (SDO) watched another sungrazer disintegrate in the sun's atmosphere. On July 5, 2011, the unnamed comet appeared to interact with plasma and magnetic fields in its surroundings as it fell apart. Could a puny comet cause a magnetic instability that might propagate and blossom into a impressive CME? The question is not so crazy as it once seemed to be.

Thank you for posting those vids Kris75. Very nice :flop:

Well here is rhe CME for today. The full comet hit is at the end so ya may want to stop there. Seems to be very popular. I should have checked before making my vid.

Any way enjoy

This ejection is blown out from the same area as the explosion that happened when the U.F.O. type object that some people believe was a sun diving comet hit the sun, makes me wonder if it blew a hole in the sun and whats up with the C.M.E.s spiral shape? It looks like its spinning!

Huge one today Oct 4 ,2011

It is short and I put in SDO view of a hot spot. I can not verify it is the same ejection as the SOHO C2 captures.

Enjoy

NASA filmed a video of a comet crashing into the sun on Oct. 3rd, and the flare that blows out from the other side suggests the comet did have an effect on the sun

A bright comet headed right towards the Sun and disintegrated (Oct. 2, 2011). It was a sungrazing comet of the type known as a Kreutz sungrazer and a particularly bright one at that. There is not a definitive orbit calculated for it yet, but most sungrazing comets have orbits that take them very close to the Sun without actually quite hitting it. However, getting so close almost always destroys these comets, so we see them going in, but not going back out.

The bright object above and to the left of the Sun in the LASCO C3 (blue) still and video clip is the planet Mercury.

The question of whether a sungrazing comet can somehow trigger a coronal mass ejection is an intriguing one. So far, the feeling is that apparent relationship between some comets and some mass ejections is simply one of co-incidence. At this stage of the solar cycle, the Sun is producing many mass ejections--in fact there were several earlier in the day--and it probably just happened by chance that one of them was around the same time as the approach of the comet. Some researchers have been looking for a more direct relationship, but nothing as yet has come out of these efforts.

Most of the effect comes from the solar x-ray flare; however, understanding the full X-ray and EUV spectral variability will help space weather modelers refine the physical understanding of this complex phenomenon and improve the accuracy of the models.
