Abstract:
Study of the variability of the quiet solar atmosphere covering as
large as possible range of the temperatures using both the 2D imaging
and 1D spectra was the aim of SoHO JOP 78 observations.
Supergranular cells were the objects of our main interest.
This programme is based on the cooperation of several
SoHO instruments (SUMER, CDS, MDI, EIT) and TRACE.
Justification of the JOP, cooperation of instruments and specially
arranged measurements for the post-facto coalignment of data from
different instruments are described in this paper.
