Introduction
Solar flares are much more common than coronal mass ejections (CMEs). Nevertheless the standard model for a solar flare essentially requires the prior or simultaneous occurrence of a CME. How do we reconcile this discrepancy? A comparison of flare properties, for flares with and without CMEs, would seem like an obvious place to start. In this Nugget we tackle this question as regards the X-ray properties, basing our study on recent lists of powerful (hence easy-to-study) major flares without CMEs.
