CME strikes Earth, sparks solar storm; but it can get worse, reveals NOAA; here is why

[ad_1] It has been said multiple times that the Sun will pick up solar activity as it ramps up to the peak of its solar cycle, but we are finally witnessing the onset of it. Last month was riddled with solar storms and short-wave radio blackouts triggered by solar flares. Now, things are getting worse. According to the National Oceanic and Atmospheric Administration (NOAA), a coronal mass ejection (CME) hit the Earth a few hours ago and sparked a minor solar storm. While it is not very dangerous, things are going to get worse. The space weather monitoring agency also revealed that another CME is on its way, and it can cannibalize the former to produce a really strong solar storm on Earth later today.According to a report by Spaceweather.com, “A CME hit Earth's magnetic field on Dec. 1st...

NASA detects CME that can partially hit Earth on Nov 30 and spark solar storm; Auroras expected

[ad_1] On Sunday, a coronal mass ejection (CME) struck the Earth sparking a 15-hour-long solar storm that peaked at G2-class intensity. The impact was so strong that auroras were visible across most of Europe despite it being a moonlit night. As the planet is still recovering from it, NASA models have detected yet another CME that is partially targeting the southern hemisphere of the planet. It can reach the Earth by November 30, and early reports suggest that while the storm is expected to be a minor one, it will still spark auroras at high latitudes.Dr. Tamitha Skov, a space weather physicist, posted on X and said, “The Sun aims south! A partly Earth-directed #solarstorm launched today. NASA & NOAA agree, a glancing blow is expected early November 30. This one is going mainly sout...

Sun releases multiple CMEs; One to spark solar storm, trigger auroras on Nov 25, says NASA

[ad_1] Solar activity has witnessed a massive spike since last week. Space agencies and researchers have noted regular solar flare eruptions, an increase in the number of sunspots, and bombardment of coronal mass ejections (CMEs). While not all of this solar activity is Earth-directed, some of it has affected our planet as well. In the last 24 hours, there have been two incidents of short-wave radio blackouts sparked by M-class solar flare eruptions, and now, NASA has revealed that a CME is also headed for us. It can hit us on November 25 and spar auroras, as per early readings by prediction models. According to a report by SpaceWeather.com, “Just today multiple overlapping CMEs have billowed away from the Sun. A NASA model already suggests one may be heading for Earth…could hit our pla...

M-class solar flare erupts on the Sun, shows NASA; blackouts triggered on Earth, solar storm possible

[ad_1] Yesterday, a massive sunspot spanning 200,000 kilometers containing as many as 12 dark cores was reported on the Sun. As per information from the NASA Solar Dynamic Observatory (SDO), there was a high chance that it could explode at any moment, and that is exactly what happened just an hour ago. An M-class solar flare was seen erupting on the sunspot, whose extreme ultraviolet radiation sparked a short-wave radio blackout on the Earth. While NASA has not been able to confirm the presence of any Earth-bound coronal mass ejection (CME), this information should be revealed in a few hours' time.According to a post made on X by the official account of Space Weather Live, the explosion occurred on the newly discovered and fast-expanding sunspot, which is already geoeffective. The post ...

From sparking powerful solar storms to causing forest fires, know the dangers of solar winds

[ad_1] Solar winds have been part of the reason behind the recent series of solar storms that have struck the Earth in the last couple of weeks. They either sparked solar storm incidents or amplified an active storm. But often, we tend to overlook its potential to cause damage when compared to solar flares and coronal mass ejections (CME). However, as per NASA officials and research papers, these stellar winds are capable of not only sparking solar storms but also triggering forest fires, and damaging spacecraft, potentially putting the lives of astronauts in danger.What are solar winds?Solar winds are not winds since space is entirely vacuum and air does not exist there. These ‘winds' are powerful waves of plasma that are created in the corona of the Sun. They contain both solar partic...

Earth to suffer direct CME hit, new NASA model reveals; To spark solar storm and auroras

[ad_1] Yesterday, the NASA Solar and Heliospheric Observatory (SOHO) detected a coronal mass ejection (CME) that appeared to be coming towards the Earth. The early assessment revealed that it could hit the Earth in the late hours of November 11, although it wasn't clear whether the strike would be a direct one or a glancing blow. Earlier today, NASA ran the data through its prediction model and we have a much clearer picture of what is to come. The CME is now expected to hit the Earth tomorrow, November 12. It is also expected to be a head-on collision, and the solar storm can reach an intensity of G2-class.Tamitha Skov, space weather physicist, and solar storm enthusiast, posted on her X account about the NASA model and said, “A #Solarstorm Encore: A new direct hit comes!

Extremely RARE auroras sparked by solar storm captured over India

[ad_1] Earth faced a triple threat from CMEs that were hurled out by the Sun on November 5, and 6, and all of them hit the planet. This sparked a dangerous G3-class geomagnetic storm. Interestingly, the effects of the solar storm did not subside until November 7 and in fact it deteriorated just a little to a G2-class storm. Unlike G1 or G2 solar storms which are minor, G3 storms have the potential to cause drag in the upper atmosphere and push smaller satellites around, causing both disruption of signals as well as damage to sensitive instruments. While no such incidents were reported this time, the G3 solar storm caused stunning auroras that were visible in various parts of the world, including in Ladakh, India.Rare aurorasThe Indian Astronomical Observatory (IAO) which is operated by ...

NASA SOHO spots CME headed for Earth tomorrow; Solar storm may spark auroras, radio blackouts

[ad_1] Even with just six Earth-facing active sunspots on the Sun, the solar activity in the last fortnight has been more intense than many months combined this year. This is the second most intense solar storm spell we have seen since March when two G3-class storms were spotted in the same month. To make matters worse, it is not likely to stop anytime soon. The NASA Solar and Heliospheric Observatory (SOHO) has detected a halo-shaped coronal mass ejection (CME) headed towards the Earth. The data highlights that it will make strike the Earth tomorrow, November 11, in the late hours, triggering a solar storm that can be as intense as G2-class.According to a report by SpaceWeather.com, “Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) detected a halo CME leaving the sun....

Solar storm creates history? Powerful strike sparks RARE auroras in Peru

[ad_1] There are some things we know about solar storms. First is that they strike the Earth near the polar region, due to the magnetic field lines of our planet. We also know that this is why auroras are primarily seen in the high latitude regions, as due to high concentrations of charged particles in the atmosphere, oxygen and nitrogen get ionized and create these fantastic colors. As the charged particles move down south, the charged particles dissipate and auroras are not visible. However, the solar storm strike on the night of November 5 and early morning of November 6 might well have created history after sparking auroras as far south as the equator itself. Tamitha Skov, a renowned space weather physicist who has previously worked with NASA, shared this information on an X post an...
