A multi-viewpoint comparison of the velocity field of coronal propagating disturbances
Nina Stankovic, Huw Morgan, Marilena Mierla +3
Small-scale propagating disturbances (PD) are ubiquitous in the solar corona. Time-Normalised Optical Flow (TNOF) is a method developed for mapping PD velocity fields in time serie…

Extreme-ultraviolet transient brightenings in the quiet-Sun corona : Closest-perihelion observations with Solar Orbiter/EUI
Nancy Narang, Cis Verbeeck, Marilena Mierla +9
The extreme-ultraviolet (EUV) brightenings identified by Solar Orbiter, commonly known as campfires, are the smallest transient brightenings detected to date outside active regions…
