Reconnection in a rotation-dominated magnetosphere and its relation to Saturn's auroral dynamics [PDF]
, 2005 The first extended series of observations of Saturn's auroral emissions, undertaken by the Hubble Space Telescope in January 2004 in conjunction with measurements of the upstream solar wind and interplanetary magnetic field (IMF) by the Cassini ...

Rotation Angle for the Optimum Tracking of One-Axis Trackers [PDF]
, 2013 An equation for the rotation angle for optimum tracking of one-axis trackers is derived along with equations giving the relationships between the rotation angle and the surface tilt and azimuth angles.

Evidence of a Quasiperiodic Global-scale Oscillation in the Near-surface Shear Layer of the Sun
The Astrophysical Journal Letters, 2023 We present evidence of hitherto undiscovered global-scale oscillations in the near-surface shear layer of the Sun. These oscillations are seen as large-scale variations of radial shear in both the zonal and meridional flows relative to their mean values.

Study on the relation of the solar coronal rotation with magnetic field structures
Scientific Reports, 2023 Daily solar spectral irradiances (SSIs) at the spectral intervals 1–40, 116–264 and 950–1600 nm and four categories of solar small-scale magnetic elements ( $$MF_{no}$$ M F no , $$MF_{anti}$$ M F anti , $$MF_{tran}$$ M F tran and $$MF_{in}$$ M F in ) are

Supergranular Fractal Dimension and Solar Rotation
, 2022 We present findings from an analysis of the fractal dimension of solar supergranulation as a function of latitude, supergranular cell size and solar rotation, employing spectroheliographic data in the Ca II K line of solar cycle no. 23.

Field-aligned currents are strongly modulated by corotating solar wind high-speed streams
Journal of Space Weather and Space ClimateBirkeland field-aligned currents (FACs) are associated with solar wind-magnetosphere energy coupling leading to substorms/convection events. FAC intensity enhancements have been studied during geomagnetic storms driven by interplanetary coronal mass ...

The 27-Day Oscillation in Ionospheric Total Electron Content Observed by GNSS
AtmosphereThe 27-day oscillation in total electron content (TEC) is analysed by means of world maps of TEC. The TEC maps are derived from measurements of the ground receiver network of the Global Navigation Satellite System (GNSS) and are provided by the ...

Anti‐solar differential rotation
Astronomische Nachrichten, 2004 AbstractThe differential rotation of anti‐solar type detected by observations for several stars may result from a fast meridional flow. The sufficiently intensive meridional circulation may be caused by large‐scale thermal inhomogeneities or, perhaps, by tidal forcing from a companion star.

The Relative Position of the Solar Magnetic Dipole Axis and Rotation Axis of the Sun
GalaxiesWe estimated the relative location of the solar rotation axis and the magnetic axis of the solar dipole, which were defined as centers of polar coronal holes.
