Resumen:
An observing campaign (SOHO JOP 139), coordinated between ground based
and SOHO instruments, has been planned to obtain simultaneous
spectroheliograms of the same area in several spectral lines. The
chromospheric lines Ca II K, Hα and Na I D as well as He I 10830,
5876, 584 and 304 Ålines have been observed. These observations
allow us to build semi-empirical models of the atmosphere before and
during a small flare. With these models, constructed to match the
observed line profiles, we can test the He abundance value.
