Sulfur fractionation in coronal plumes as observed by Solar Orbiter/SPICE
Slimane Mzerguat, Miho Janvier, Eric Buchlin +4
Coronal plumes are bright, narrow structures rooted in coronal holes that contribute to the solar wind. Their composition, particularly elemental fractionation as a function of fir…
Spatial distributions of EUV brightenings in the quiet-Sun
C. J. Nelson, L. A. Hayes, D. Müller +16
The identification of large numbers of localised transient EUV brightenings, with small spatial scales, in the quiet-Sun corona has been one of the key early results from Solar Orb…
First Solar Orbiter observation of a dark halo in the solar atmosphere
Serena Maria Lezzi, David M. Long, Vincenzo Andretta +5
Solar active regions (ARs) are often surrounded by dark large areas of reduced emission compared to the quiet Sun, observed at various wavelengths corresponding to chromosphere, tr…
Coronal voids and their magnetic nature
J. D. Nölke, S. K. Solanki, J. Hirzberger +68
Extreme ultraviolet (EUV) observations of the quiet solar atmosphere reveal extended regions of weak emission compared to the ambient quiescent corona. The magnetic nature of these…
Evolution of dynamic fibrils from the cooler chromosphere to the hotter corona
Sudip Mandal, Hardi Peter, Lakshmi Pradeep Chitta +17
Dynamic fibrils (DFs) are commonly observed chromospheric features in solar active regions. Recent observations from the Extreme Ultraviolet Imager (EUI) aboard the Solar Orbiter h…
Initial radiometric calibration of the High-Resolution EUV Imager () of the Extreme Ultraviolet Imager (EUI) instrument onboard Solar Orbiter
S. Gissot, F. Auchère, D. Berghmans +21
The telescope was calibrated on ground at the Physikalisch-Technische Bundesanstalt (PTB), Germany's national metrology institute, using the Metrology L…
EUV brightenings in the quiet-Sun: Signatures in spectral and imaging data from the Interface Region Imaging Spectrograph
C. J. Nelson, F. Auchère, R. Aznar Cuadrado +13
Localised transient EUV brightenings, sometimes named `campfires', occur throughout the quiet-Sun. However, there are still many open questions about such events, in particular reg…
Slow solar wind sources. High-resolution observations with a quadrature view
Krzysztof Barczynski, Louise Harra, Conrad Schwanitz +16
The origin of the slow solar wind is still an open issue. One possibility that has been suggested is that upflows at the edge of an active region can contribute to the slow solar w…
Temperature of Solar Orbiter/EUI quiet Sun small scale brightenings: evidence for a cooler component
A. Dolliou, S. Parenti, F. Auchère +16
Context: On 2020 May 30, small and short-lived EUV brightenings were observed in the Quiet Sun (QS) during a four minutes sequence by EUI/HRIEUV on board Solar Orbiter. Their physi…
Prominence eruption observed in He II 304 Å up to $>6 R_\sun$ by EUI/FSI aboard Solar Orbiter
M. Mierla, A. N. Zhukov, D. Berghmans +24
We report observations of a unique, large prominence eruption that was observed in the He II 304 Å passband of the the Extreme Ultraviolet Imager/Full Sun Imager telescope aboard S…
Extreme UV quiet Sun brightenings observed by Solar Orbiter/EUI
D. Berghmans, F. Auchere, D. M. Long +23
The goal of this paper is to study the smallest brightening events observed in the EUV quiet Sun. We use commissioning data taken by the EUI instrument onboard the recently launche…
