Urgent warning over intense solar storms strong enough to cripple the world's internet for WEEKS - as NASA confirms we've hit the explosive peak in the sun's 11-year cycle

Daily Mail  

Every 11 years, our sun becomes a chaotic sphere that shoots out huge bursts of energy towards Earth – a period known as the 'solar maximum'. In a teleconference this, NASA, the National Oceanic and Atmospheric Administration, and the Solar Cycle Prediction Panel confirmed that the sun has reached its solar maximum period, which could continue for the next year. …

Radio blackouts reported across the world after 'tsunami' of solar storms make impact - and NOAA warns more disturbances are to come

Daily Mail  

Radio blackouts caused by a 'tsunami' of solar storms were reported across the globe on Thursday, and scientists say more disruptions are are on the way. The sun released at least 15 streams of plasma, or coronal mass ejections, in the last 24 hours that caused communications disturbances over parts of Africa and Asia when they impacted Earth. Parts of …

Chinese researchers uncover driving source of umbral waves in sunspots

China Daily  

KUNMING -- Chinese researchers have recently studied the structure of chromospheric umbral waves in sunspots and discovered the driving source of umbral waves, according to the Yunnan Observatories under Chinese Academy of Sciences. Researchers studied the fine structure of chromospheric umbral waves in two sunspots by using the Interface Region Imaging Spectrograph and data from other telescopes. Furthermore, by analyzing …

The Hindu  

A powerful solar storm on the Sun a week ago produced beautiful aurorae over many parts of the earth on May 10. Such solar storms are more frequent when the Sun nears the peak of its solar cycle — an 11-year period in which the Sun’s magnetic field flips direction. After two solar cycles, the Sun completes one ____ cycle …

ABC  

On the weekend, parts of Australia witnessed an auroral display not seen for more than 20 years. "It's determined by what the orientation of the magnetic field is in the solar wind," Dr Carter said. "If the orientation of the magnetic field in the solar wind is weaker — we say northward — Earth's magnetic field acts as an effective …

During ‘total solar eclipse’ on April 8, Sun will be in a period of ‘solar maximum’. What it means?

Hindustan Times  

A total solar eclipse is a phenomenal celestial event that will occur on Monday, April 8, as the Moon will entirely obscure the Sun, unlike a partial solar eclipse, during which only a portion of the Sun is obscured. Meanwhile, NASA shared a video on Friday explaining that this eclipse occurs during the ‘solar maximum’ period, which increases the possibility …

Will Earth get hit with a major solar storm? Risk of blackout arises after eight sunspots emerge on the Sun

India TV News  

The activities in the solar system attract many. Things are again heating up in the sun due to which eight new sunspots have emerged on the Earth-facing side of the solar disk. Due to this, there are possibilities that X-class solar flares and radiation storms can pose a harmful impact on the GPS system. GPS users should remain vigilant near …
