This module is aimed at providing quasi real-time information on the actual conditions of the solar atmosphere.
The input data are sequences of visible-light coronagraphic images acquired by the SOHO/LASCO-C2 coronagraph and EUV full-disk images acquired by SDO/AIA in the 193 Å channel. LASCO images are calibrated with standard routines and monthly background models are applied to remove K-corona, F-corona, and stray light; then they are enhanced by using the NRGF filter distributed within the SolarSoft. Full-resolution AIA images are calibrated with the standard SolarSoft routines and then enhanced with standard IDL filters.
The temporal evolution as observed with these instruments over the last 24 hours is provided every 6 hours with a two-panel synchronized movie, where the clock indicates the UT time.
