The bursts from the sun, called coronal mass ejections, carried southward magnetic fields and would have clashed with Earth's northward field, causing a shift in electrical currents that could have caused electrical transformers to burst into flames, Luhmann said.
The flares have sent off bursts of radiation from the Sun, known as coronal mass ejections (CMEs).
Magnetic loops in the solar corona, solar flares and coronal mass ejections are among the phenomena that scientists still cannot fully explain.
These solar eruptions, known as coronal mass ejections, possess an amount of energy on the order of a billion atomic bombs, Wang says.
Among specific topics are understanding the differences in three consecutive large flares, the nature of prominence bubbles and plumes, the inversion of physical parameters in solar coronal magnetic structures, coronal mass ejections as a result of magnetic helicity accumulation, and dynamic features of the current sheet associated with the 2010 August 19 solar flare.
Dr Li added: "We don't yet know what causes these coronal mass ejections and that is really what we hope to discover.
Massive bursts of energy, such as solar flares and coronal mass ejections, also occur more frequently when the solar cycle peaks.
The display was expected to begin as the flares, known as coronal mass ejections, began to slam into the Earth's magnetic field late last night.
The US National Oceanographic and Atmospheric Administration (Noaa) said that three coronal mass ejections (CMEs) were en route as the result of solar flares on the 13, 14 and 15 February (GMT).
