    Hey, guys, I watched the video of the Magnetosphere. As usual, I'm seriously lacking in expertise here, and I want to understand what I'm seeing...but don't. Can you give me a quick run through? And, as always, it is much appreciated

    Much Love,
    Hi 1inMany, here is a simple explanation of what happens when a solar storm hits earth and how it affects the earth´s magnetic field. ie. the magnetosphere.
    The focus is on auroras but you will get an idea on how the magnetosphere sometimes "dances".






    From spaceweather.com
    Quote FARSIDE ERUPTION: Sunspot AR1402, the source of last week's X-flare and many beautiful auroras, is on the farside of the sun now. Although we can't see it, the active region is still erupting. During the late hours of Jan. 31st, the Solar and Heliospheric Observatory observed this coronal mass ejection flying over the sun's western limb:

    The cloud is heading in the direction of NASA's STEREO-Ahead spacecraft, which witnessed the explosion from directly above the sunspot. An initial inspection of the data suggests that no planets are in the line of fire.

    If AR1402 hangs together for another two weeks, it will complete its transit of the farside and re-emerge on the Earthside of the sun. A return is unlikely, however, because sunspots rarely last for more than one solar rotation.

    Wow. I needed that video. Thank you so, so much IH! So, when I go back to the vid about magnetosphere, the red and the blue lines...are the same lines as in this vid? And they become more active and entangled when there is more activity from the sun?

    Just yesterday spaceweather.com posted this:

    Quote BACK TO WORK (UPDATED): After a quiet weekend with no flares of any significance, the sun went back to work on Monday morning and launched a bright coronal mass ejection (CME) into space. The Solar and Heliospheric Observatory recorded the expanding cloud during the early hours of Feb. 6th:

    Update: New images from the Solar Dynamics Observatory (SDO) show that this was a frontside event. The explosion occured when a magnetic filament draped over the sun's northeastern limb rose up and snapped. An extreme UV movie from SDO shows the structure lifting off.
    And then, last night we got this:

    Quote M-CLASS SOLAR FLARE: Departing sunspot AR1410 is growing in size and magnetic complexity as it approaches the sun's northwestern limb. The region is now crackling with solar flares, highlighted by this M1-class eruption on Feb. 6th at 20:01 UT:



    NOAA forecasters estimate a 30% chance of more M-flares during the next 24 hours. Any eruptions from AR1410 are unlikely to be Earth-directed as the active region continues to turn away from our planet.
    Since then, 1410 has shot off a few C-flares, but they should not be Earth effective due to the position on the solar disc (far NE limb).

    Yep. It was.
    Here you go!




    Form spaceweather.com
    Quote NORTHEASTERN ERUPTION: Solar activity is picking up. During the late hours of Feb. 9th, a dark magnetic filament winding over the sun's northeastern limb rose up and exploded. NASA's Solar Dynamics Observatory recorded the action:


    The eruption hurled a bright coronal mass ejection (CME) away from the sun: SOHO movie. The expanding cloud is not heading for Earth, but in a day or so it might make contact with Venus, which appears to be in the line of fire.

    The emergence of a new sunspot at the root of the erupting filament plus the rapid growth of existing sunspot AR1416 could foreshadow more activity in the days ahead.

    Some updates:-

    From spaceweather.com
    Quote SUNSPOT OF INTEREST: For the second day in a row, sunspot AR1416 has doubled in size:


    Moreover, it has developed a "beta-gamma" magnetic field that harbors energy for M-class solar flares.
    Any such eruptions this weekend would be Earth directed as the sunspot turns to face our planet.

    THE SUN TODAY: 11 February 2012 - The Start of Something BIG





    And from Skyywatcher88
    SOLAR ACTIVITY UPDATE: Trio of C-Class Flares/Approaching AR (Feb 12th, 2012).

    Quote Analysis of Solar Active Regions and Activity from 10/2100Z
    to 11/2100Z: Solar activity was low due to a trio of C7 x-ray
    events. Regions 1416 (S19W02) and 1417 (N16E44) each produced C7
    events at 10/2352Z and 11/1854Z respectively. The third C7 event was
    observed at 11/1004Z from behind the east limb near N25. The
    activity behind the NE limb portends the return of old Region 1402
    (N26, L=218). Region 1416 continued its growth phase, both in area
    and spot count, and maintained a beta-gamma magnetic configuration.
    At about 10/1900Z, a 27 degree long segmented filament erupted in
    the NE quadrant of the disk. The ENE to WSW oriented filament was
    centered at N29E14. An associated CME was observed lifting of the NE
    limb, first visible in SOHO LASCO C2 imagery at 10/2012Z.

    From spaceweather.com:

    Quote SUBSIDING STORM: A geomagnetic storm (Kp=5) that began during the early hours of Feb. 15th when the IMF tipped south is subsiding. Nevertheless, solar wind conditions remain favorable for high-latitude auroras. During the storm, Northern Lights descended as far south as Minnesota in the United States.

    SWEET LIGHTS: For reasons not fully understood by forecasters, a disturbance rippled through Earth's magnetic field on Feb. 14th. Perhaps it was Cupid's arrow. The impact sparked some sweet lights around the Arctic Circle:

Nevertheless, solar wind conditions remain favorable for high-latitude auroras. During the storm, Northern Lights descended as far south as Minnesota in the United States.

    SWEET LIGHTS: For reasons not fully understood by forecasters, a disturbance rippled through Earth's magnetic field on Feb. 14th. Perhaps it was Cupid's arrow. The impact sparked some sweet lights around the Arctic Circle:

    "On several occasions the sky was full of auroras from horizon to horizon," says photographer and aurora tour guide Chad Blakley of Abisko National Park, Sweden. "We had many happy couples celebrating with us tonight. Most of our guests agreed that it was the best Valentine's day that they had ever shared together."

    There has been some speculation that the display was caused by a CME, launched from the sun on Feb. 10th and reaching Earth on Feb. 14th. However, there is no clear signature of a CME impact in local solar wind data.

    Update: Geomagnetic activity intensified even more on Feb. 15th when the interplanetary magnetic field (IMF) near Earth tilted south, opening a crack in Earth's magnetic field. Solar wind poured in and fueled a G1-class geomagnetic storm, now subsiding.
    That means that more charged particles have entered our atmosphere. Expect large earthquakes (which have already begun to occur) and more unusual weather, et al ....

    Here's an update from spaceweather.com:

    Quote AURORA WHIRLPOOL: Sometimes the sky surprises us. On Feb. 14-15, with little warning, geomagnetic activity rippled around the Arctic Circle, producing an outbreak of auroras that veteran observers said was among the best in months. At the height of the display, a US Defense Meteorological Program satellite photographed a whirlpool of Northern Lights just north of the Bering Sea:





    They came from outer space--and you can have one! Genuine meteorites are now on sale in the Space Weather Store.

    QUIET SUN: With no sunspots actively flaring, the sun's output has flatlined again. NOAA forecasters put the chance of an M-class flare during the next 24 hours at no more than 1%. Solar activity should remain low. Solar flare alerts: text, voice.

    AURORA WHIRLPOOL: Sometimes the sky surprises us. On Feb. 14-15, with little warning, geomagnetic activity rippled around the Arctic Circle, producing an outbreak of auroras that veteran observers said was among the best in months. At the height of the display, a US Defense Meteorological Program satellite photographed a whirlpool of Northern Lights just north of the Bering Sea:

    "A number of images from the DMSP F18 satellite captured the dramatic auroral event of the last couple nights," says analyst Paul McCrone, who processed processed the data at the US Navy's Fleet Numerical Meteorology and Oceanography Center in Monterey, CA.

    The reason for the outburst is still not completely clear. It got started on Feb. 14th when a magnetic disturbance rippled around the Arctic Circle. No CME was obvious in local solar wind data at the time; the disturbance just ... happened. Once begun, the disturbance was amplified by the actions of the interplanetary magnetic field (IMF) near Earth. The IMF tipped south, opening a crack in our planet's magnetic defenses. Solar wind poured in and fueled the auroras.

    I wonder, could someone explain to me - in simple terms - why the number of days with Sun spots has increased so dramatically in the past few years, or point me to a post where this was explained?

    I know I could find t by searching the web, but since there are people here who obviously understand these things, it makes sense to ask it here.


    From SpaceWeather:

    Spotless Days
    Current Stretch: 0 days
    2012 total: 0 days (0%)
    2011 total: 2 days (<1%)
    2010 total: 51 days (14%)
    2009 total: 260 days (71%)
    Since 2004: 821 days
    Typical Solar Min: 486 days
    Updated 15 Feb 2012


    From 260 spotless days in 2009 to merely 51 spotless days in 2010, to TWO days in 2011?
    Why?

    I apologise if this was discussed before. I haven't noticed it.

    Hi NeverMind,
    the following video (done in 2011) describes how the sun goes through an 11 year solar cycle..
    In 2012 this cycle is reaching another peak level ie. many more sunspots.

    Here is some really good info on auroras:

    Quote What are Northern Lights?

    The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora australis' in the south..
    Auroral displays appear in many colours although pale green and pink are the most common. Shades of red, yellow, green, blue, and violet have been reported. The lights appear in many forms from patches or scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky with an eerie glow.

    What causes the Northern Lights?

    The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Variations in colour are due to the type of gas particles that are colliding. The most common auroral color, a pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora.


    The connection between the Northern Lights and sunspot activity has been suspected since about 1880. Thanks to research conducted since the 1950's, we now know that electrons and protons from the sun are blown towards the earth on the 'solar wind'. (Note: 1957-58 was International Geophysical Year and the atmosphere was studied extensively with balloons, radar, rockets and satellites. Rocket research is still conducted by scientists at Poker Flats, a facility under the direction of the University of Alaska at Fairbanks - see web page http://www.gi.alaska.edu/


    The temperature above the surface of the sun is millions of degrees Celsius. At this temperature, collisions between gas molecules are frequent and explosive. Free electrons and protons are thrown from the sun's atmosphere by the rotation of the sun and escape through holes in the magnetic field. Blown towards the earth by the solar wind, the charged particles are largely deflected by the earth's magnetic field. However, the earth's magnetic field is weaker at either pole and therefore some particles enter the earth's atmosphere and collide with gas particles. These collisions emit light that we perceive as the dancing lights of the north (and the south).


    The lights of the Aurora generally extend from 80 kilometres (50 miles) to as high as 640 kilometres (400 miles) above the earth's surface.
    http://www.northernlightscentre.ca/northernlights.html

    Therefore, a strong CME or strong solar wind (which results in geomagnetic storms) can cause a breech in the magnetosphere wherein the charged solar wind/plasma enters our atmosphere. Those charged particles excite oxygen and/or nitrogen molecules causing them to gain/lose electrons temporarily. The almost instantaneous release of these newly acquired charges release photons (visible colored light) creating the aurora effect.

    WOW! Although most sources do not show any strong solar activity in any data that I can find (at the moment), we are having a Proton Flux which usually follows strong M-class or X-class flares.



    That "thing" on the sun looks like a huge filament eruption....hmmmmm. I'll be looking into this today and will update if I find anything else.

    spaceweather.com has this:

    Quote CANYON OF FIRE: A magnetic filament snaking over the sun's northeastern limb rose up and erupted during the early hours of Feb. 24th. The eruption split the sun's atmosphere creating a "canyon of fire," shown here in a movie captured by the Solar Dynamics Observatory:



    The glowing walls of the canyon are formed in a process closely related to that of arcade loops, which appear after many solar flares. Stretching more than 400,000 km from end to end, the structure traces the original channel where the filament was suspended by magnetic forces above the stellar surface.

    As erupting magnetic filaments often do, this one launched a coronal mass ejection (CME) into space. The Solar and Heliospheric Observary recorded the expanding cloud: movie. The CME does not appear to be heading for Earth or any other planet.
