“D” region Prediction

With a broad range of user groups that range from the aviation community, to satellite programs, to general enthusiasts like pigeon racers and aurora watchers, SWPC’s web page offers each of these user groups a dashboard specific to the data sets and information that affects them.

The electric power grid, and consequently the power to your home and business, can be disrupted by space weather. One of the great discoveries of the 19th century was the realization that a time-varying magnetic field is able to produce an electrical current in a conducting wire. The basic idea is that the time rate of change of the magnetic flux (i.e. lines of magnetic force) passing through a current loop is proportional to the current that

INEFFECTIVE CME IMPACT: As predicted, a CME struck Earth’s magnetic field on June 10th (1725 UT). However, the weak impact was ineffective; it did not cause a geomagnetic storm. The CME was hurled into space by an M9.7-class flare from sunspot AR3664/3697 on June 8th. CME impact alerts: SMS Text

3 MILLON YEARS AGO, AN INTERSTELLAR CLOUD HIT EARTH: Today, Earth is in a safe space. Like all the other planets in the Solar System, it is cocooned within the sun’s magnetic field–a giant bubble called “the heliosphere.” The heliosphere protects us from dangerous things in the Galaxy like interstellar clouds and cosmic rays.

3 million years ago, the heliosphere may have collapsed. A new paper just published in Nature Astronomy argues that a dense cloud of gas hit the Solar System, compressing the heliosphere to a fraction of its usual size.

THE POLAR VORTEX WOBBLED IN DECEMBER: Last month, sky watchers in Europe saw something rare and beautiful. A giant bank of polar stratospheric clouds (PSCs) escaped the Arctic Circle, and for more than a week they filled skies with rainbow color as far south as Italy. In the Italian comune of Sanfrè (latitude +45N), Pablo Javier Lucero was able to photograph the clouds at all hours of the day:

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
