The services of the INSAT-4A satellite were disrupted for over 30 minutes at 4 pm this afternoon (January 2, 2007) due to solar disturbances. A press release from the Indian Space Research Organisation said the satellite "lost earth lock" when one of the momentum wheels used for stabilising it got switched off at around 4 pm.

"ISRO engineers at the Master Control Facility in Hassan (Karnataka) immediately took action to recover the earth lock and orient the satellite properly within half an hour", following which the services were restored, the release said.
