Today’s Current Affairs: Solar Storms Ignite Spectacular Auroras
In today’s current affairs, May 2024 has brought one of the most dazzling natural shows to the sky – a series of intense solar storms that resulted in some of the most colorful and widespread aurora displays in 500 years. These solar storms began on May 7 with powerful solar flares and culminated in multiple Coronal Mass Ejections (CMEs) traveling at speeds up to 3 million mph, reaching Earth from May 10. This created a stunning geomagnetic storm, rating G5, the highest on the geomagnetic storm scale.
People worldwide witnessed magnificent green, purple, and pink lights dancing across the skies, visible even at unusually low latitudes like the southern U.S. and northern India. It’s a historic event comparable to the legendary storms of 1958 and 2003.
NASA invites everyone who captured these extraordinary auroras to send their photos, aiding scientists in better understanding such solar activities. With contributions from citizen scientists, this event will be studied for years, shedding light on space weather impacts on our planet and beyond.

What caused the intense aurora displays in May 2024?
The intense auroras in May 2024 were caused by powerful solar storms, which included strong solar flares and coronal mass ejections (CMEs). These solar events sent large amounts of solar particles toward Earth, creating the beautiful light displays.
How did the solar storms start and progress?
The solar storm activity started on May 7 with two intense solar flares. Between May 7 and May 11, there were multiple strong solar flares and at least seven CMEs headed toward Earth. The most powerful type of flares, called X-class flares, were observed, with the strongest reaching X5.8. On May 14, an even stronger X8.7 flare was recorded, the most intense one of this solar cycle.
What speeds did the CMEs reach and when did they impact Earth?
The CMEs traveled at speeds up to 3 million mph and began impacting Earth on May 10. These waves of solar particles created a prolonged geomagnetic storm with a G5 rating, the highest level on the geomagnetic storm scale.
Where were the auroras visible during this event?
The auroras from this event were visible at unusually low latitudes, extending as far as the UK, southern parts of the U.S., and northern India. The most intense displays occurred on the night of May 10 and continued through the weekend.
How does this storm compare with historic solar storms?
This recent storm is comparable to historic solar storms from 1958 and 2003 based on the disturbance storm time index. Auroras were seen at magnetic latitudes as low as 26 degrees, making this one of the most significant aurora events in the past 500 years.
How can photographers contribute to studying these solar events?
Photographers who captured images of the auroras can contribute to scientific research by sharing their photos with NASA. These images help scientists study and understand solar storms better. Participation in citizen science projects is encouraged as it provides valuable data.
How did citizen scientists help during this event?
Thousands of citizen scientists submitted their observations to the Aurorasaurus project, helping NASA gather extensive data. Even reports of not seeing the auroras are helpful for understanding the full impact of the event.
Why is it important to study solar storms and their effects on Earth?
Studying solar storms is crucial for understanding their impact on Earth’s upper atmosphere, satellites, manned missions, and other infrastructure. This knowledge helps improve models and predictions to mitigate potential disruptions caused by space weather.
What future missions will assist in studying solar storms?
Upcoming missions such as NASA’s Geospace Dynamics Constellation (GDC) and Dynamical Neutral Atmosphere-Ionosphere Coupling (DYNAMIC) will provide more detailed measurements of Earth’s atmospheric responses to solar energy surges. These missions will also support NASA’s Artemis missions to the Moon and future Mars missions.
Today’s Current Affairs highlight an incredible celestial event. In May 2024, Earth experienced one of the most intense aurora displays in the last 500 years due to powerful solar storms. These storms produced stunning green, purple, and pink lights dancing across the skies worldwide. If you were lucky enough to capture this phenomenon in a photo, you can contribute to science by sending your pictures to NASA. Such contributions help scientists understand and study solar storms better.
May 2024 Solar Storms
The solar storm began on May 7 with two strong solar flares and continued to intensify until May 11, delivering multiple powerful X-class flares. On May 14, the storm peaked with an X8.7 flare, the strongest seen in this solar cycle. These solar events sent waves traveling at speeds up to 3 million mph towards Earth, creating a geomagnetic storm of G5 level, the highest on the geomagnetic storm scale.
“The combination of these arriving CMEs created a historic storm,” said NASA scientist Elizabeth MacDonald.
The Result – Auroras!
The auroras were visible in places as far south as the UK, southern U.S., and even northern India, with the most vibrant displays seen on the night of May 10. Some sightings were reported from the Balkans too!
This storm ranks alongside historic ones from 1958 and 2003 in terms of both intensity and the wide reach of auroras.
Your Contribution to Studying Solar Flares
Elizabeth MacDonald emphasized that even standard cell phone cameras today are sensitive enough to capture aurora colors. NASA's Aurorasaurus project received thousands of reports and images from citizen scientists. Such data are invaluable for studying solar events and their effects on Earth. The impact of solar storms on satellites, manned missions, and space-based infrastructure remains a crucial area of study for NASA’s ongoing and future missions, including those to the Moon and Mars.
