Description:
ASPIICS coronagraph offers unique capabilities to study the early evolution of (off-limb) CMEs. Thanks to its reach from below 1.1 to 3 solar radii, ASPIICS will fill the gap between the disk imagers (like SDO/AIA) and upper-corona observations by, for example, LASCO C2 (2 - 6 solar radii) and C3 (3.7 - 30 solar radii) coronagraphs. However, even with its reach, ASPIICS will not be able to observe the actual source regions of CMEs (AR or destabilized prominences/filaments) on the solar disk. To provide this missing piece of the puzzle of CME origin, we will conduct coordinated observations during (and prior to) several ASPIICS 6-hour-long observing windows. These coordinated observations will allow us to capture unique sequences of changing magnetic field topology before the CMEs are triggered (SOT) and study the response of the cool plasma (IRIS) and hot plasma (XRT, EIS) during and immediately after the CME onset.
