\"GOES3_VIS_1545_18MAY1980\"<\/a>

GOES-3 Visible Image from 18 May 1980 at 1545 UTC (Click to enlarge)<\/p><\/div>\n

GOES-3 started service on 16 June 1978 and was the operational GOES-West satellite until the late 1980s. Having lost imaging capabilities, it started a second long life as a communications satellite; GOES-3 is currently the oldest operating satellite. Decommissioning will begin on 8 June and run for 15 days. If final decommissioning happens as planned on 23 June, GOES-3’s service life will be 38 years, 7 days.<\/p>\n

GOES-3’s arguably most famous imagery occurred during the eruption of Mount St. Helens on 18 May 1980, shown above (click here<\/a> for an animation of the eruption, courtesy of Barry Roth, SSEC; Tim Schmit, NOAA\/ASPB also provided longer visible animations: MP4<\/a> | animated GIF<\/a>).<\/p>\n

A comparison of GOES-3 Visible (0.65 \u00b5m) and Infrared Window (11.5 \u00b5m) images, below, showed that a large portion of the volcanic cloud exhibited IR brightness temperatures of -60\u00ba C (darker red color enhancement)<\/em> or colder as the feature moved rapidly eastward during the first 10 hours following the eruption. It is interesting to note that a small “enhanced-V” or cold\/warm (-65\u00baC\/-47\u00baC) thermal couplet signature was evident on the initial 1545 UTC<\/a> Infrared image (zoom<\/a>), as the volcanic ash cloud rapidly rose to an estimated altitude of 12 to 16 miles (20 to 27 km) above sea level.<\/p>\n
