In the early hours of May 22, 2013, GOES-13 suffered a loss of its ability to properly track the stars - the system that keeps its sensors pointed towards Earth. While engineers began working on the situation, NOAA quickly switched GOES-15 into a non-standard mode of capturing full hemisphere images every 30 minutes - the typical frequency that GOES-13 collects data. This image shows the coverage of the GOES-15 full hemisphere imagery (blue line) overlaid with the coverage area that GOES-13 provides over the Continental United States (green line). No loss is suffered over the U.S., though the coverage from the GOES-13 full hemisphere scans is somewhat affected. Luckily, coverage over the Atlantic can be covered by the EUMETSAT Meteosat-10 satellite (red line) that is positioned at 0 degrees longitude and covers the Atlantic and Europe/Africa regions. GOES-14, NOAA's backup geostationary satellite, will resume GOES-13's area of coverage on May 23, 2013.
