The Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun (ASPIICS) is a novel externally occulted solar coronagraph that will be launched on board the Project for On-Board Autonomy (PROBA-3) mission in 2023. The external occulter will be placed on the first satellite ∼150 m ahead of the second satellite, which will carry an optical instrument. During 6 hours per orbit, the satellites will fly in a precise formation and will constitute a giant externally occulted coronagraph. The large distance between the external occulter and the primary objective will allow observations of the white-light solar corona starting from extremely low heights of ∼1.1 R ⊙ . 3PRODPROBA3/ 3PRODPROBA3/ 3PRODPROBA3 NO Sun: corona instrumentation: high angular resolution telescopes methods: numerical Zhukov, A N Inhester, B Dolla, L Mierla, M Astronomy & Astrophysics 652 2021 A4 sergei.shestov@observatoire.be https://www.aanda.org/10.1051/0004-6361/202140467 published in REFERD
