The agency believes having this kind of technology is crucial in keeping astronauts and Earth safe from coronal mass ejections.
"Right now, space weather forecasters issue at most a one-day warning--sometimes just a few hours--that a coronal mass ejection might cause a damaging geomagnetic storm here on Earth," says NCAR's Mausumi Dikpati, lead author of a paper on the research that was published recently in Scientific Reports.
Although coronal mass ejections can happen several times a day during the sun's most active 11-year cycle, the blasts are usually small or weak compared to the 2012 and 1859 events, she 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.
