Sun emits massive solar flare with potential to impact satellite communications CESSI
New Delhi Apr 20 PTI The sun unleashed a massive solar flare on Wednesday with the potential to impact satellite communications and global positioning systems the Centre of Excellence in Space Sciences India CESSI saidThe X22 class solar flare eruption took place at 357 UTC 927 IST from the solar magnetic active region AR12992 Dibyendu Nandi Professor and Head of CESSI at the Indian Institute of Science Education and Research in Kolkata told PTISolar flares are powerful bursts of energy that can impact radio communications electric power grids and navigation signals and pose risks to spacecraft and astronautsThis flare is classified as X-class which denotes the most intense flares while the number provides more information about its strengthBlackout of satellites is proprietary information and is unlikely to be made public Nandi saidStrong ionospheric perturbation is ongoing over India South East Asia and the Asia-Pacific regions Expected high frequency communication blackouts satellite anomalies GPS scintillations airline communication impacts the CESSI said on TwitterNandi said the impact of a solar flare is almost immediate as it releases extremely high-energy photons that travel at the speed of light and affect the sunlit portion of the earthHe said since not much can be done after the eruption of a solar flare it is important to predict it a task the CESSI has been undertaking with the help of studentsNandi said the CESSI had predicted the eruption of an X-class flare on April 18The Space Weather Prediction Centre of the National Oceanic and Atmospheric Administration NOAA said the strong flare was associated with multiple bursts on specific radio frequencies to include a burst of 509 solar flux units on 2695 MHzAdditionally a Type II radio sweep was detected by the USAF Radio Solar Telescope Network RSTN with an estimated velocity of 1630 kilometres per second it saidAccording to the US-based National Aeronautics and Space Administration NASA the biggest flares are known as X-class flares based on a classification system that divides solar flares according to their strength The smallest ones are A-class near background levels followed by B C M and X it saidAccording to the NASA similar to the Richter scale for earthquakes each letter represents a 10-fold increase in energy output An X-class flare is 10 times an M-class eruption and 100 times a C-class flare PTI SKU RC
