Sun Produces An X1.7 Solar Flare, Followed By An X2.8
2013-05-13 12:04:28

Lawrence LeBlond for redOrbit.com - Your Universe Online On Sunday (May 12) the Sun emitted a significant solar flare that is being classified as the first X-class event of 2013. The X1.7 flare, which peaked at about 10 p.m. EDT, was also associated with another solar event known as a coronal mass ejection (CME). While CMEs can release radiation and solar material in the direction they were produced, Sunday´s phenomenon was not directed at Earth. While solar flares also have the...

SDO Captures 3 Years Of Sun Activity In Spectacular Video
2013-04-22 19:09:25

Lee Rannals for redOrbit.com — Your Universe Online NASA has released a video of the unbroken coverage of the sun for the past three years, taken by its Solar Dynamics Observatory (SDO). The spacecraft's Atmospheric Imaging Assembly snaps a shot of the sun every twelve seconds in ten different wavelengths. The latest video shows the past three years of the sun at a pace of two images per day. [ Watch the Video: Three Years With Solar Dynamics Observatory ] The video,...

Twin Peaks For Solar Cycle?
2013-03-02 07:29:34

redOrbit Staff & Wire Reports - Your Universe Online While 2013 is supposed to be the year of Solar Max - the peak of the 11-year sunspot cycle - the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks. According to NASA, sunspot numbers during the months of January and February 2013 were well below values recorded back in 2011. Furthermore, they report that...

SORCE Satellite Outlasts Mission Life And Keeps On Truckin'
2013-01-24 13:13:38

Lee Rannals for redOrbit.com — Your Universe Online Some missions in space complete their operations just after predicted, while others earn the Iron Man award for outlasting their primary mission. In the case of SORCE--a satellite designed to study solar storms--it's earned itself an Iron Man. Solar Radiation and Climate Experiment (SORCE), designed and built by the University of Colorado, is a NASA satellite that gives scientists a look at some of the most intense solar...

How Solar Activity Affects Our Planet
2013-01-10 11:02:17

NASA Science In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle. There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National...

Solar Flare Heads Towards Earth
2012-11-13 15:54:05

Lee Rannals for redOrbit.com - Your Universe Online NASA said that the sun emitted a mid-level solar flare on Tuesday that has the potential of causing some radio blackouts. The solar flare reached a classification of M6, which falls into the weakest flares that are still able to cause some space weather effects near Earth. According to the National Oceanic and Atmospheric Association's Space Weather Scales, this M-class flare can cause a radio blackout categorized as R2, or...

NASA Observatory Captures Another X-Class Solar Flare
2012-10-23 15:32:34

[WATCH VIDEO: Active Region On The Sun Emits Another Flare] Lee Rannals for redOrbit.com — Your Universe Online NASA said its Solar Dynamics Observatory (SDO) captured the sun erupting with an X1.8 class solar flare on Monday. The solar flare came from an active region on the left side of the sun known as AR 1598, which has been the source of weaker flares. The "X-class" solar flares are the most intense flares, with the number near the X representing its intensity. An X2...

Solar Flare Captured By SDO
2012-07-31 13:47:29

Lee Rannals for redOrbit.com - Your Universe Online NASA's Solar Dynamics Observatory (Solar Dynamics Observatory) captured a mid-level solar flare on Saturday, showing us that the sun is getting prepped for its solar maximum. SDO witnessed the image on the active region of the sun named AR 1532 in the 131 Angstrom wavelength. This wavelength is typically colorized as teal, and is particularly good for catching flares, NASA said. Solar flares emit powerful bursts of radiation, which...

Researchers at Reading University said that solar storms are likely to become more disruptive to planes and spacecraft within decades. The team predicts that once the Sun shifts towards an era of lower solar activity, more hazardous radiation will reach Earth. The researchers said in Geophysical Research Letters that the Sun is currently at a grand solar maximum, which is a phase that began in the 1920s. Mike Lockwood, professor of space environment physics at Reading, said in a statement:...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
