A new weather satellite will monitor both Earth and space-based weather. The GOES-U mission will gauge storm severity on Earth and track solar storms. ... an eye on space weather as solar activity ...
Space weather is a branch of space physics and aeronomy, or heliophysics, concerned with the varying conditions within the Solar System and its heliosphere. This includes the effects of the solar wind , especially on the Earth's magnetosphere , ionosphere , thermosphere , and exosphere . [ 1 ]
Solar activity has been on a declining trend since the 1960s, as indicated by solar cycles 19–24, in which the maximum number of sunspots were 201, 111, 165, 159, 121 and 82, respectively. [14] In the three decades following 1978, the combination of solar and volcanic activity is estimated to have had a slight cooling influence. [15]
The Space Weather Prediction Center is one of the nine National Centers for Environmental Prediction (NCEP) and provides real-time monitoring and forecasting of solar and geophysical events, conducts research in solar-terrestrial physics (i.e. heliophysics), and develops techniques for forecasting solar and geophysical disturbances.
The flare comes amid increasing solar activity that has brought a run of intense space weather in recent days and weeks. Only a day before, the Sun had released a slightly less powerful but still ...
A new artificial intelligence model trained on decades of data on the Sun’s activity would have predicted the unexpected intense solar storm that struck the Earth last year, scientists say.. In ...
The official planetary K p-index is derived by calculating a weighted average of K-indices from a network of 13 geomagnetic observatories at mid-latitude locations.Since these observatories do not report their data in real-time, various operations centers around the globe estimate the index based on data available from their local network of observatories.
An example of space weather: Aurora australis in the Earth's atmosphere observed by Space Shuttle Discovery, May 1991. Space weather is the environmental condition within the Solar System, including the solar wind. It is studied especially surrounding the Earth, including conditions from the magnetosphere to the ionosphere and thermosphere.
