I've mentioned in the past that among other things, we rely on the #Meteosat geostationary satellites to monitor #MtEtna. Even though the spatial resolution is low (the sub-satellite pixel has a nominal resolution of 3km), these satellites provide information at a high temporal rate: MSG (Meteosat Second Generation) provides full-disk images are available every 15 minutes, and a RSS (Rapid Scan Service) that only covers Europe, with data available every 5 minutes. The RSS satellite is also located at 9° of longitude east, so there is less distortion on the Etna (~15° longitude).

The main downside of RSS is that the service is not continuous: every 26 days, the satellite goes into “Full Earth Scan” mode for two days: this is needed to keep the mechanisms in good working order, and the data from these scans is NOT made available, which means that every 26 days there's a 2-day hole in the RSS data.

And obviously this happens during an ongoing #eruption. Murphy's law strikes again!
