Resumen:
On 29 March 2014, a Moreton wave was detected with very high cadence with the Halpha SolarTelescope for Argentina (HASTA). The wave was associated with an X1 flare in AR 12017 and a coronalmass ejection (CME). We analyze the connection between the Moreton wave and the EUV signaturesobserved with the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory (SDO/AIA).We study the kinematics of the wave fronts along several directions using stack plots and find links betweenthe features observed in the chromosphere and low corona at various wavelenghts. We also analyze theassociation between the waves and the CME. To explain the propagation of the observed EUV wave frontsand their chromospheric traces, we propose a 3D geometrical model based on an expanding and outwardtravelingcoronal shock-wave front that intersects the solar sphere. Finally, we discuss the particularconditions of the coronal medium and the possible origin of the shock wave.
