The Martian dust storm was first spotted by NASA's Mars Reconnaissance Orbiter(MRO) on
November 10 and has been tracked ever since,the space agency said.Using Orbiter's mars colour
imager, Bruce Cantor of Malin Space Science Systems,began observing the storm and reported it to the team operating NASA's Mars Exploration Rover Opportunity

The storm came no closer than 1347 km from Opportunity, resulting in only a slight drop in atmospheric
clarity over that rover,which does not have a weather station.
