Location
The Gauribidanur Observatory is located at Gauribidanur (Latitude:13.60° N; Longitude:77.44° E), 100 km north of Bengaluru.
Science and Observation
The Observatory has been used for studying various aspects of the Sun, galaxies and pulsars.
A few observations with the array have been the first two-dimensional images of radio emission from slowly varying discrete sources in the outer solar corona, an all-sky survey of radio sources at 34.5 MHz in the declination range -30° S to 60° N, and a low frequency carbon recombination lines in astrophysical sources.Studies have been also been done of gaseous remnants of exploding stars and the apparently vacant space between members of a cluster of galaxies. Currently, the studies are targeted at pulsars.
Facilities
The Gauribidanur Observatory has a 6meter radio telescope (GEETEE), a radio heliograph (GRH), a high resolution radio spectrograph and a gravitational laboratory.
Gauribidanur Telescope (GEETEE)
The Gauribidanur Telescope (GEETEE) is a decameter wave radio telescope. It consists of 1000 dipoles arranged in a "T" configuration. It consists of 1.4 km East-West Arm and a 0.5 km South Arm.
Gauribidanur Radio Heliograph (GRH)
The Gauribidanur Radio Heliograph (GRH) is a radioheliograph used to obtain two dimensional pictures of the outer solar corona at frequencies from 40-150 MHz. The GRH has been operating since 1997. It consists of 192 log-periodic dipole (LPD) arranged in a "T" configuration.
