Satellite infrared image

This image shows a view of Northern Chile, updated every three hours with about 45mn lag. It is produced using the 3rd and 4th channel of the satellite GOES8 centered respectively at 6.7 and 10.7 microns, the dotted lines marks the latitude/longitude with a 2 degrees spacing (check SSEC Data Center or local user infos in case of outdated images). The time indicated on the image corresponds to the start of the scan of the spinning radiometer (a full earth north-south scan takes 26 mn). The exact recording times of the Chajnantor, Paranal and La Silla pixels are respectively 18.10, 18.43 and 19.38 minutes after.

A zoom on the Observatories area in the Water Vapor (left) and Thermal Infrared (right) channels:

Chajnantor: [-23.02,-67.75]

Paranal: [-24.63,-70.40]

La Silla: [-29.25,-70.73]

Tololo-Pachon: [-30.23,-70.72]

Casleo: [-31.80,-69.25]
