| heal.abstract | We present two dimensional maps of the longitudinal magnetic field, obtained in the Ca I 6103 Angstrom line, as well as line of sight velocity maps in H alpha for an active region. The observations were obtained with the Tower telescope of the Sacramento Peak Observatory and the Universal Birefrigent Filter, with circular polarization measurements. The comparison of the photographs in the wing of H alpha, where the Ellerman bombs (EBs) are best observed, with the corresponding magnetic maps shows that very few EBs are associated with small scale magnetic elements, while the great majority, especially the brighter ones, appear at the boundaries of magnetic features. The comparison of EBs with the velocity maps in the wings of H alpha shows that most of them coincide with blue wing intensity excess; near the brightest EBs ascending motions are observed. We also found a very good coincidence of EBs with photospheric facular granules. | en |
