This is the worst of the satellites today. The Indian Ocean is always finding heat when the rest of the planet doesn't. April 28, 2005 at 22:44 gmt, India is actually five and a half hours ahead of gmt and this places this satellite somewhere around 3:45 in the early morning. The area is in darkness actually. In visual satellites there is a lot of clouds and that is why there is an accumulation of heat. The heat is held under the clouds.
