Real time at Jicamarca
The Jicamarca Radio Observatory (JRO) is the equatorial anchor of the Western Hemisphere chain of incoherent scatter radar (ISR) observatories extending from Lima, Peru to Søndre Strømfjord, Greenland. The JRO is the premier scientific facility in the world for studying the equatorial ionosphere. It consists of three 1.5 MW transmitters and an antenna array of 18,432 dipole elements, covering an area of approximately 85,000 m2. The study of the equatorial ionosphere is rapidly becoming a mature field due in large part to the contributions made by the Jicamarca Radio Observatory.

The Observatory is about  half an hour drive inland (east) from Lima and 10 kms from the Central Highway (latitude 11.95° South, longitude 76.87° West - Satellite Image here). The magnetic dip angle is about 1°, and varies slightly with altitude and year. The radar can accurately determine the direction of the Earth's magnetic field and can be pointed perpendicular to B at altitudes throughout the ionosphere. The altitude of JRO is about 520 meters ASL.
