Calibration of Electrically Short Antennas Using the l = 2 Spherical Harmonic Expansion Coefficients of the Radio Brightness Distribution on the Sky Between 0.5 and 6.8 MHz

Radio Science, Volume 60, Issue 8, August 2025.
Abstract A space‐borne radio‐frequency antenna is typically located in the vicinity of a conductive spacecraft body that influences its beam. Also, at wavelengths that greatly exceed the sizes of such an antenna and spacecraft, the antenna is expected to have the beam of an equivalent short dipole.

Narrow Coronal Mass Ejections

The Astrophysical Journal, 2001
Narrow coronal mass ejections (CMEs), defined arbitrarily as events whose apparent angular width is 15° or less, are a small subset of all CMEs. Little is known of the properties of these events and whether these properties differ from those of the larger, more typical CMEs. We have included in this study 15 narrow CMEs observed in the period from 1999

Modeling Polarized Radio Sounding Observations of a Coronal Mass Ejection

The Astrophysical Journal
Coronal mass ejections (CMEs) evolve significantly as they propagate from the Sun to the Earth, so remote observations of their changes in speed, strength of the magnetic field, density, and overall structure are critical for predicting their arrival ...

Simulation of Galactic Cosmic Ray Proton Fluxes With the Daily Modulation Parameter: Validation With AMS‐02 Data for 2011–2019

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract The flux of galactic cosmic rays (GCRs) is modulated by solar activity on different time scales. This is often described with the force‐field approximation via the single variable parameters of the modulation parameter, which formally corresponds to the average rigidity loss of GCR particles in the heliosphere. The force‐field approximation is

Solar Wind Heavy Ions and Alpha Particles Within Earth's Magnetosphere and Their Variability With Upstream Conditions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract Working toward the goal of understanding solar wind (SW) entry to the Earth's magnetosphere, this study examines solar‐origin ion composition in the magnetotail. During its trajectory, Wind spent a significant amount of time in the Earth's magnetotail, where its SupraThermal Ion Composition Spectrometer (STICS) measured the mass and mass per ...

A probabilistic approach to the drag-based model

Journal of Space Weather and Space Climate, 2018
The forecast of the time of arrival (ToA) of a coronal mass ejection (CME) to Earth is of critical importance for our high-technology society and for any future manned exploration of the Solar System. As critical as the forecast accuracy is the knowledge
