An impulsive solar flare measuring M1.9 erupted from Region 1675 on February 17, 2013. The event started at 15:45, peaked at 15:50 UTC and ended at 15:52 UTC. A 10cm Radio Burst was recorded from 15:47 – 15:51 UTC.Space Weather Message Code: SUM10RSerial Number:
A weak interplanetary shock was registered by ACE spacecraft at 10:58 UTC on February 16, 2013. This event is not expected to bring widespread geomagnetic disturbances, however, it sparked aurora displays at very high latitudes.The Kp index is currently at 4, very
The following video is a time-lapse movie of the aurora displays over Large Animal Research Station (LARS), University of Alaska Fairbanks (UAF) from February 13, 2013 captured by Taro Nakai, a researcher of micrometeorology (dynamics of the interaction between plant
We are now fully into solar maximum and the United Nations is taking steps to organize an international response to space weather effects. Space weather was added to the regular agenda of the COPUOS Science and Technical Subcommittee, which means the UN is recognizing
A solar flare registered as C8.7 was detected at 00:21 UTC on February 6, 2013. The source of the flare was decaying Active Region 1667. According to images from NASA’s STEREO-B spacecraft, the associated CME appears to be heading in the Earth direction, with expected
A large filament stretching hundreds of thousands of kilometers erupted on Thursday, January 31, 2013. The eruption lasted about 4 hours and was located in the northeast quadrant of the Sun.The following SDO video shows a variety of views of the break-up of this
An Earth-directed Coronal Mass Ejection (CME) on January 31, 2013 (07:09 UTC) was accompanied by a large prominence eruption best visible in light with a wavelength of 304 angstroms. NASA’s Solar Dynamics Observatory captured this footage from 10 p.m. EST (03:00 UTC)
Solar activity remained at low levels for the past 24 hours. However, there were two large prominence eruptions on January 23, 2013. First large prominence erupted from the southern limb in early hours, producing south-directed CME cloud, away from Earth. It was
From NASA Goddard Space Flight Center. NASA’s The Fermi Gamma-ray Space Telescope has been catching brief outbursts of high-energy light that are mysteriously produced above thunderstorms. The outbursts, known as terrestrial gamma-ray flashes (TGFs), last only a few
Active Region 1654 has traveled half across the Earth facing side of the Sun and now is squarely facing Earth. On January 13, this huge sunspot reached its maximum size measured as more than 193 000 km (120, 000 miles) wide long or 15 Earth diameters) from end to
