Serendipitous Observations of Polar Crown Filament Eruption
During synoptic observations on 04/17 at 17:57, XRT observed a possible post-eruption cusped arcade on the northeast limb in Al-poly. Only two images of this phenomenon were captured with Hinode (left); however, the EIT He II line (right) shows an impressive prominence in this region prior to the XRT images.
