The Rarotonga MF radar is operated by Colorado Research Associates with initial support from the National Science Foundation (NSF) and current support from the National Aeronautics and Space Administration (NASA) as a Ground-Based Instrument for the TIMED satellite mission, which is part of the joint TIMED-CEDAR program of NASA and NSF.

Instrument/Model Description

The Rarotonga, Cook Islands (21.21S, 159.77W; 2 m alt) 1.98 MHz MF radar has been in operation since 2000. On day 359 of 2001 at 89 km altitude, the apex magnetic coordinates were (-22.9, -84.9) degrees. The magnetic inclination and declination angles were -39.5 deg and 13.5 deg. The magnetic local time at 0 Universal Time (UT) is about 1316 MLT. The solar local time (SLT) is UT minus 10 hours and 39 minutes (-159.77/15.=-10.651).
