More Eye-Popping Video from the June 7 Solar Explosion

Here’s more video from the huge explosion on the Sun on June 7, 2011, which began at about 06:41 UTC. Not only was this event one of the most spectacular ever recorded, but also one of the best observed, with complementary data from several spacecraft and different vantage points. This video shows data from three different space observatories. The Solar Dynamics Observatory’s Atmospheric Imaging Assembly recorded the amazing event in stunning detail in different wavelengths. Additionally, the Solar & Heliospheric Observatory’s (SOHO) LASCO coronagraph and STEREO’s (Solar Terrestrial Relations Observatory) SECCHI instrument suite observed the prominence and associated CME as they traveled out into the heliosphere. Using LASCO and SECCHI data, the speed of the leading edge of the CME was estimated to be in the range 1200 – 1600 km/s. Model calculations predict that Earth will receive a glancing blow of the CME on June 10, possibly sparking some nice aurorae at high latitudes, according to the SDO team.

The size of the prominence is thought to be at least 75 times the size of Earth. Our Jason Major created a graphic showing the size comparison. Earth is the little teeny tiny blue circle in the top left corner:

Interesting that there seems to be a 'harbinger' spike of energy coming out before the explosion. Especially in the last two videos, there is a long 'spike' of light coming out in the direction of the explosion which shows steadily before the explosion. In the second video there also seems to be a faint, slightly conical steady stream coming out well before the explosion.

Has anyone seen any mention of this idea anywhere else? Perhaps it's just my imagination, but it seems like I saw this pattern also on an earlier explosion.
