The propagation and damping of slow magnetoacoustic waves in the solar atmosphere [PDF]
The propagation and damping of slow magnetoacoustic waves in the solar atmosphere is investigated, with particular emphasis placed on waves with periodicities of five minutes. The basic model of a uniform temperature loop is extended by the addition of

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances
Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...

Coronal Waves and Oscillations
Wave and oscillatory activity of the solar corona is confidently observed with modern imaging and spectral instruments in the visible light, EUV, X-ray and radio bands, and interpreted in terms of magnetohydrodynamic (MHD) wave theory.

Preface to the special issue on “Old records for new knowledge”
Studying a changing world requires observations going back in time to extend and contextualize our latest scientific knowledge. Old legacy data exist in non‐digital formats. Thus, techniques and methodologies for the preservation, dissemination, interpretation, homogenization, calibration, and use of such legacy data and their associated metadata, as ...

Hard X-Ray Quasiperiodic Pulsations in X-class Solar Flares Observed by Aditya-L1/HEL1OS
We present the catalogue of quasiperiodic pulsations (QPPs) detected in hard X-ray (HXR) observations of X-class solar flares obtained with the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) instrument on board Aditya-L1 during 2024 July–2026 March.

Flux Rope Eruption and Associated Vertical Prominence Oscillation
We present a plane-of-sky observational analysis of a solar eruptive event that occurred on 2 September 2023. The flare peaked at approximately 07:00 UT, closely aligning with the impulsive acceleration phase of the erupting flux rope, which accelerated ...

The Lorentz Force at Work: Multiphase Magnetohydrodynamics throughout a Flare Lifespan
The hour-long, gradual phase of solar flares is well observed across the electromagnetic spectrum, demonstrating many multiphase aspects, where cold condensations form within the heated post-flare system, but a complete 3D model is lacking. Using a state-

Torsional wave dispersion and dissipation in solar tornados
Aims. We investigated the nature of solar atmosphere tornados hosting torsional Alfvén waves and fast magnetoacoustic torsional waves in the context of energy transport and transfer. Methods.
