Interplanetary Scintillation of 3C273 [PDF]

Nature, 1966
IN the period between September 15 and October 14, 1965, the radio source 3C273, observed with the east-west arm of the “Northern Cross” at 408 Mc/s, showed interplanetary scintillation. Comparison of the three records obtained with the three independent beams of the instrument excludes spurious effects due to instability or interference.

Interplanetary Scintillation — Preliminary Observations at 103 MHz [PDF]

Symposium - International Astronomical Union, 1980
A 3-station interplanetary scintillation (IPS) observatory is being developed mainly with a view to study the solar wind plasma. The first IPS telescope operating at 103 MHz at Thaltej near Ahmedabad has been put into regular operation since April 1979.

A Bayesian Inference‐Based Empirical Model for Scintillation Indices for High‐Latitude

Space Weather, 2021
Solar wind parameters, the solar radio flux index (F10.7), the Sun's declination and the SuperMAG Electrojet index are used to construct a Bayesian inference‐based empirical model for scintillation indices (S4 and σΦ) at high latitudes.

SEPARATING NIGHTSIDE INTERPLANETARY AND IONOSPHERIC SCINTILLATION WITH LOFAR [PDF]

The Astrophysical Journal Letters, 2016
ABSTRACT Observation of interplanetary scintillation (IPS) beyond Earth-orbit can be challenging due to the necessity to use low radio frequencies at which scintillation due to the ionosphere could confuse the interplanetary contribution. A recent paper by Kaplan et al.

A pilot study of interplanetary scintillation with FAST [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Observations of interplanetary scintillation (IPS) are an efficient remote-sensing method to study the solar wind and inner heliosphere. From 2016 to 2018, some distinctive observations of IPS sources like 3C 286 and 3C 279 were accomplished with the Five-hundred-meter Aperture Spherical radio Telescope (FAST), the largest ...

Developments in the use of EISCAT for interplanetary scintillation [PDF]

Annales Geophysicae, 2008
The antennas of EISCAT have been used for interplanetary scintillation (IPS) studies of the solar wind for many years. The main science found from these studies is obtained through the cross-correlation of signals from antennas having the longest ...
