The ASPIICS coronagraph aboard the European Space Agency’s formation-flying Proba-3 mission\u00a0is able to\u00a0observe\u00a0the Sun\u2019s corona in the gap between the fields of view of solar extreme-ultraviolet imagers and conventional coronagraphs, making it uniquely suited for studies of the inner solar corona.\u00a0<\/p>\n
This time-lapse animation captures a coronal mass ejection (CME) in the top right, combining observations made on 16 July over a period of one hour and a half by three different European instruments aboard different missions: the Sun\u2019s disc and low corona (artificially coloured in yellow), as captured by an\u202fextreme-ultraviolet telescope\u202f(SWAP) aboard\u202fProba-2; the outer corona (in red) observed by the\u202fLASCO C2 coronagraph\u202faboard\u202fSOHO; and the inner corona (in green), imaged in detail by Proba-3\u2019s\u00a0ASPIICS coronagraph, filling the gap.\u00a0<\/p>\n
Andrei Zhukov from the\u202fRoyal Observatory of Belgium, Principal Investigator for the ASPIICS coronagraph aboard Proba-3, comments: \u201cYou can see the CME starting at the edge of the solar disc, captured by Proba-2. Then it extends into the inner coronal region, which is now visible to us thanks to Proba-3, before reaching the high corona\u00a0observed\u00a0by SOHO. The continuity with which we can now\u00a0observe\u00a0the CME structure extend outwards from the Sun is incredible.\u201d\u00a0\u00a0<\/p>\n
