New Approaches to the Identification of Sources and the Onset of Stealth Coronal Mass Ejections

— New approaches to the identification of sources and the onset of stealth coronal mass ejections (CMEs) are discussed based on the stealth CME of July 7, 2012. It is shown that the generation of this stealth CME is accompanied by various manifestations of short-term and small-scale activity in the region of its formation in the form of bursts of UV radiation (a microflare), as well as the activation and movement of loop-like structures. The features of the behavior of the photospheric magnetic field in the region of observation of the microflare are studied. The formation of a frontal CME structure there can be considered evidence that the stealth CME is generated in a solar atmospheric region with detected manifestations of solar activity.
