Source Surface Height Optimisation for Improved Solar Wind Velocity Forecasting Across Solar Cycles 23, 24 and 25
Sandeep Kumar, Nandita Srivastava, Dana-Camelia Talpeanu
The potential field source surface (PFSS) model is a cornerstone of many state-of-the-art space weather forecasting frameworks. It includes a single physical free parameter, the so…
On the Relationship between Solar Spicules and Propagating Coronal Disturbances: The Role of Shocks
Ravi Chaurasiya, Sankalp Srivastava, Piyali Chatterjee +3
Spicules and propagating coronal disturbances (PCDs) are ubiquitous dynamic features of the solar atmosphere, yet their physical connection remains an open question of paramount im…
Observations of a Twin Pair of Atypical Solar Flares and a Magnetic-reconnection Scenario
Satyam Agarwal, Alphonse C. Sterling, Shibu K. Mathew +3
We present observations and a magnetic-reconnection scenario of a twin pair of "atypical flares" that occurred on 2022 April 22 in a quadrupolar magnetic configuration formed by tw…
HEL1OS -- A Hard X-ray Spectrometer on Board Aditya-L1
Anuj Nandi, Manju Sudhakar, Srikar Paavan Tadepalli +33
HEL1OS (High Energy L1 Orbiting X-ray Spectrometer) is one of the remote sensing payloads on board Aditya-L1 mission designed to continuously monitor and measure the time-resolved…
An Unusual Velocity Field in a Sunspot Penumbra
H. Balthasar, C. Denker, A. Diercke +6
The photospheric Evershed flow is normally oriented radially outward, yet sometimes opposite velocities are observed not only in the chromosphere but also in the photospheric layer…
Source location and evolution of a multi-lane type II radio burst
P. Zucca, P. Zhang, K. Kozarev +8
Shocks in the solar corona can accelerate electrons that in turn generate radio emission known as type II radio bursts. The characteristics and morphology of these radio bursts in…
