These maps are normally updated hourly between 1400 and 2300 UTC. However, this near-real-time system is automated, so if a system problem occurs outside of regular working hours, it will not be fixed until the following work day.

Please, do not forget to press “Reload” (Netscape) or “Refresh” (Internet Explorer) to update pictures.

WARNING: The data are processed in near real-time, have not been fully validated, and are preliminary.
