There are risks that one of the biggest solar flares could damage satellites of SingTel Optus. But the company has claimed that its satellites are not facing any threat from the sun flare that is likely to erupt on Friday.

It has been revealed by NASA that the giant sun spot AR1944 is a powerful burst of radiation. The space agency has confirmed that its size is seven times the width of earth. NASA has warned that damage could be caused to satellites and communications signals by solar flares.

'Even the Space Weather is bad!' is a title of a research note in which Bank of America Merrill Lynch analyst Wilton Fry has said that satellite operators could defend their space equipment by rotating their sensitive solar arrays away from the sun when the flare erupts.

He said that the sun is all set to hurl the giant sun spot to the earth with an enormous amount of ionizing solar radiation. He added, "The US Department of Defence estimated in 2000 that disruption to US government satellites from space weather was in the region of $US100 million each year".

He urged people not to panic or sell their stocks in satellite-related companies as the damage is likely to be relatively small.
