7689 20260105140559.0 OUTRART-2026-0001 Panesar, Navdeep K. Buildup, Explosion, and Untwisting of a Solar Active Region Jet Observed with Solar Orbiter, IRIS, and SDO 2025 We present observations of an active region jet that was fully captured by Solar Orbiter’s Extreme Ultraviolet Imager (EUI) high-resolution imager (HRI/EUV) in the 174 Å passband. The HRI/EUV observed the jet with fast temporal cadence of 3 seconds and high spatial resolution from a pixel size of 142 km. These observations were complemented with coverage from IRIS and SDO. The jet was fully tracked by IRIS slit-jaw images and also scanned by the IRIS slit. To best of our knowledge, this paper presents the first analysis of an active region coronal jet observed by HRI/EUV together with observations from IRIS and SDO (for details see Panesar et al 2025).
