304 cool material condenses out of nowhere at a cusp (dip) seen at 171. Similar coronal condensation forming prominence/coronal rain has recently been captured (Liu, Berger, Low 2012, ApJ Letters). Shortly after this condensation, a nearby large filament/prominence erupted.

This filament is unsual in that it is aligned in a roughly north-south direction. It is observed to evolve and fade away in 304. Just after the end of this movie SDO does a cruciform maneuver.

This filament has footpoints behind the limb since there is a lack of footpoint brightening in the EUV images.

The tall-standing bright loops disappear after the eruption. Instead, one finds a post-eruption arcade closer to the core of the AR.

The following attributes suggest an emerging flux region just behind the limb: 1. Very dynamic loops structures, 2. Frequent surges (optically thick material) in the foreground of the EUV loops, and 3. A localized brightening, possibly due to reconnection event(s). Surges are commonly found in the periphery of emerging flux regions as the emerging magnetic field impinges on pre-existing neighbouring field. The squeezing of the field could squirt dense material into a surge.

The Earth transit has clearly caused the large filament to erupt producing an EUV wave. The preceding M6.6 flare is purely coincidental.

From 31 Jan through 2 Feb, the visible side of the Sun showed a big active region AR 1967 in the souther hemisphere coming toward central meridian. In addition, another region AR 1968 was seen in the norther hemisphere. Together there were 10 M-class flares. Every time an intense flare occurred in one of these regions, space weather fans wishfully thought they would launch a CME that could affect the heliosphere. This seemed to be all wrong, however. It is true that a CME can be harder to see if it arises from a region close to disk center, but the appearance of the associated coronal dimming indicates that the flares from AR 1967 or 1968 were not associated with major CMEs. Perhaps these regions were embedded in strong magnetic field environment. The trans-equatorial loops between them also seemed to be quite stable. During this period CMEs were mostly from backside regions occasionally producing clear dimming over the southwest limb and marginal dimming over the east limb. The CME source identification has been done using STEREO data.
