Abstract:
From a search of the SOHO/LASCO CME Catalog, we found several flares
that were strong but short-lived in GOES X-ray flux (peak flux > C5,
duration <~2 hr), and produce no CME. We also found several equaly
strong and short-lived flares that did initiate CMEs. All of the flares
were located in strong magnetic fields near sunspots and were spatially
compact (brightened only a small part of the active region.  From the
magnetic location and magnetic surroundings determined from MDI
magnetograms, it appears that the non-CME flares were confined deep
within surronding strong closed magnetic fields, while the CME-producing
flares either triggered neighboring sheared fields to erupt into a CME,
or were able to erupt out of the active region and directly drive a CME.
Compact ejective flares of this last type may produce a large CME by
driving the eruption of a large coronal loop such a a trans-equatorial
loop.  We present an example of such a flare and CME.
