We try to assess the validity of assumptions taken when deriving drift velocity. We give simple formulas for characteristics of the spatiotemporal correlation function of the observed diffraction pattern for the frozen flow and the more general Brigg

The Earth's ionosphere is a coupled system affected by interactions with precipitating energetic particles and electrical currents from the Earth's magnetosphere, and in addition by upward propagating disturbances from lower atmospheric layers. Geoma

We take the frozen-in assumption of the scatter evolution and derive simple formulas for characteristics of the spatiotemporal correlation function of the observed diffraction pattern. Using Low-Frequency Array (LOFAR) Cassiopeia intensity observatio

Scintillation of beacon satellite signals or distant cosmic radio emissions can provide interesting information on the cosmic medium itself, its internal spatial structure and basic evolution characteristics. LOFAR network gives consistent scintillat

Mid-latitude trough (MIT) is the distinct structure observed in Earth’s ionosphere at high latitudes especially at the nighttimes. The phenomenon is observed at both hemispheres. As it resides at the topside ionosphere in the sub-auroral region, it

The sub-auroral region of the main ionospheric trough is a very unique area strongly affected by different type of instabilities coming from both the bottom (Earth's atmosphere) and the top (Earth's magnetosphere) neighbouring regions. The main ionos

The Earth’s auroral region and its close neighbourhood is the origin of strong radio emissions caused by complex physical plasma processes. Among them we can list auroral hiss, auroral roar, auroral medium frequency (MF) burst, and auroral kilometr

We discuss mechanisms of the generation of ultralow frequency (ULF) upstream waves in the terrestrial foreshock that are essential for the acceleration of ions in space plasmas. The analysis is based on global hybrid kinetic simulations of the magnet
