Abstract
- We examine the capability of a blast-wave scenario -associated to a coronal flare or to the expansion of CME flanks- to reproduce a chromospheric Moreton phenomenon. We also simulate the Moreton event of December 06, 2006 considering both the corona and the chromosphere. To obtain a sufficiently strong coronal shock -able to generate a detectable chromospheric Moreton wave- a relatively low magnetic field intensity is required, in comparison with the active region values. Employing reasonable coronal constraints, we show that a flare ignited blast-wave or the expansion of the CME flanks emulated as an instantaneous or a temporal piston model, respectively, are capable to reproduce the observations.<br />Comment: 11 figures, 9 pages, 1 table.
