A rare space weather phenomena caught on camera: Gigantic jets outbursts on top of the Hurricane "Hilda"

A strong outburst of lightning from Hurricane "Hilda", in the Pacific Ocean, was reported by the National Weather Service on August 10, 2015. At first, the scientist thought the lightning was the so-called sprites phenomena, however, closer observation...

Geomagnetic storm reaching G3 (Strong) levels in progress, extreme conditions possible

During the last 24 hours, solar wind parameters, measured by the ACE spacecraft, were indicative of background solar wind conditions until 07:45 UTC on August 15, when a sudden impulse occurred due to the arrival of a co-rotating interaction region (CIR) ahead of a

G1-Minor geomagnetic storm in progress

A G1-Minor geomagnetic storm is in progress as a result of coronal hole high speed stream (CH HSS) buffeting Earth's magnetic field.Effects from the CH HSS are expected to continue disrupting the solar wind environment for the rest of the July 13.By July 14,

Solar activity to fall by 60% during the 2030s to conditions last seen during the 17th century ‘mini ice age’

A new model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s 11-year heartbeat. Predictions from the model suggest that solar activity will fall by 60% during the 2030s to conditions last seen

Geomagnetic storming briefly reaches G2-Moderate levels

During the last 24 hours, solar wind parameters reflected an enhanced solar wind environment due to the onset of a co-rotating interaction region (CIR) in advance of a negative polarity coronal hole high speed stream (CH HSS). Solar wind speed increased from initial va
