Correlation of near-Earth proton enhancements >100 MeV with parameters of solar microwave bursts
Solar-Terrestrial Physics, 2017 We analyze the relations between various combinations of peak fluxes and fluences of solar microwave bursts at 35 GHz recorded with the Nobeyama Radio Polarimeters during 1990–2015, and corresponding parameters of proton enhancements with E>100 MeV ...

CME-driven Shock and Type II Solar Radio Burst Band Splitting [PDF]
Astrophysical Journal, 2018 Coronal mass ejections (CMEs) are believed to be effective in producing shocks in the solar corona and interplanetary space. One of the important signatures of shocks and shock acceleration are Type II solar radio bursts that drift with the shock speed ...

Solar Radio Burst (Type III) [PDF]
International Astronomical Union Colloquium, 1996 AbstractThis article describes the observations of a type III radio burst observed at 103 MHz simultaneously by the two radio telescopes situated at Rajkot (22.3°N, 70.7°E) and Thaltej (23°N, 72.4°E). This event occurred on September 30, 1993 at about 0430 UT and lasted for only half a minute. The event consisted of several sharp spikes in a group. The

Ichon Solar Radio Spectrogaphic System and Development of its Operation Software [PDF]
Journal of Astronomy and Space Sciences, 1997 A solar radio spectrograph for monitoring solar radio emission was installed at Ichon branch of Radio Research Laboratory in 1995. The spectrograph consists of three different antennas to sweep a wide band of frequencies in the range of 30MHz-2500MHz. We

Solar Radio Burst Events on 6 September 2017 and Its Impact on GNSS Signal Frequencies
Space Weather, 2019 During the intense solar radio bursts on 6 September 2017, Global Navigation Satellite Systems (GNSS) signal interferences were observed at ground stations in the European longitude sector from 20°N to 70°N for all GNSS satellites in view including GPS ...

An Increase of GNSS Data Time Rate and Analysis of the Carrier Phase Spectrum
Remote Sensing, 2023 Natural hazards and geomagnetic disturbances can generate a combination of atmospheric and ionospheric waves of different scales. The carrier phase of signals of global navigation satellite system (GNSS) can provide the highest efficiency to detect and ...

Solar radio emission as a disturbance of aeronautical radionavigation [PDF]
, 2018 On November 4th, 2015 secondary air traffic control radar was strongly disturbed in Sweden and some other European countries. The disturbances occurred when the radar antennas were pointing at the Sun.

Electromagnetic Simulations of Solar Radio Emissions
Journal of Geophysical Research: Space Physics, 2019 Solar radio emissions are electromagnetic waves emitted in the solar wind as a consequence of electron beams accelerated during solar flares or interplanetary shocks such as interplanetary coronal mass ejections.
