Exploring if a coronal dimming event can produce coronal hole-like properties

Adriana De-Sassi, Louise Harra, Krzysztof Barczynski +8

Coronal dimmings, or transient coronal holes, are manifested as a sudden reduction in extreme ultraviolet (EUV) and X-ray emission, often following solar eruptions. We investigate…

Pre-flare and active region plasma flows and structure seen by the short wavelength camera on SOLAR-C/EUVST

James McKevitt, Sarah Matthews, David H. Brooks +20

The mechanisms triggering solar flares and driving coronal heating occur across wide temperature ranges on small spatial scales and short timescales, making them difficult to obser…

Solar Orbiter observations of solar energetic electron events associated with hard microflares

Diane Mittaine, Andrea Francesco Battaglia, Laura Rodríguez-García +4

Generally, large solar flares accelerate electrons to high energies more efficiently than microflares. However, some microflares, known as hard microflares (HMFs), also produce hig…

The Non-Eruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence

James McKevitt, Louise Harra, Gherardo Valori +13

The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, as such eruptions frequently drive coronal mass ejections (CMEs) that impa…

Surprisingly Large Doppler Shifts in Hinode EUV Imaging Spectrometer (EIS) Solar Spectra, Resulting from an Inconspicuous Small-scale Jet in EUV Images

Alphonse C. Sterling, Louise K. Harra, Navdeep K. Panesar +1

Strong EUV lineshifts in solar spectra are generally indicative of highly dynamic and explosive events that are easily detected in comparable-wavelength EUV images, with the strong…

Near-continuous tracking of solar active region NOAA 13664 over three solar rotations

I. Kontogiannis, Y. Zhu, K. Barczynski +6

Magnetic flux emergence and decay in the Sun span from days to months. However, their tracking is typically limited to about half a solar rotation when relying on single-vantage-po…
