Scientists find faster way of predicting space weather

Scientists have identified a faster way to predict space weather using solar radio bursts (SRBs) from eruptions triggered by coronal mass ejections (CMEs) from the sun that can use ground-based instruments to quickly predict the dangers of space weather.

Solar flares, mainly caused by coronal mass ejections or solar flares, affect space weather, and space weather hazard prediction is critical as it affects satellite communications, telecommunications, the global navigation satellite system (GNSS), etc. The radiation from such solar flares is also dangerous for the astronauts and the flight crew. It is therefore a challenging task for scientists to predict and predict space weather, according to a statement from the Ministry of Science and Technology.

Forecasters use ground-based instruments and satellites to monitor the sun’s active regions for changes in order to predict dangerous space weather events. It does this primarily through remote observations of the sun’s coronal mass ejections. However, it takes 1-5 days for CMEs to reach us, which delays the follow-up for this period of time.

A team of scientists from the Indian Institute of Astrophysics (IIA), an autonomous institute of the Department of Science and Technology (DST), along with staff around the world, have reported that a type of solar radio burst was occurring with the global network of solar radio telescopes called CALLISTO (Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory) can be used to quickly predict the dangers of space weather.

“Radio bursts at low frequencies are associated with high-energy CMEs that travel far faster into the interplanetary (IP) medium, thus speeding up the tracking process,” the press release said.
