    Solar wind - currently about normal levels
    speed: 437.5 km/sec
    density: 3.8 protons/cm3

    However, an M class pulse induced a strong radio blackout on Earth

    Quote SOLAR FLARE AND RADIO BLACKOUT: Sunspot AR2257 erupted on Jan. 13th, producing an M5-class solar flare at 04:24 UT.

    A pulse of extreme UV radiation from the flare ionized Earth's upper atmosphere over Australia and the Indian Ocean.

    Mariners and ham radio operators may have noticed a brief communications blackout at frequencies below about 10 MHz.


    More flares could be in the offing. AR2257 has an unstable 'beta-gamma-delta' magnetic field that seems poised to explode again. NOAA forecasters estimate a 40% chance of M-class flares and a 10% chance of X-flares on Jan. 13th. - it's uncertain if an earth hit of a CME will happen from this event.

    Planetary K-index
    Now: Kp= 2 quiet
    24-hr max: Kp= 3 quiet


    Interplanetary Mag. Field
    Btotal: 6.8 nT
    Bz: 1.1 nT north - north oriented field structure will have a protection effect for earth's geomagnetic field from outside particle assaults.



    large coronal holes have sealed, but there is evidence in the image of potential for hole formation (see dark areas in image)

    In certain locations the aurora was quite bright and geometrical

    Solar wind - slowing down a little bit, with a little less proton count than normal.. Definitely a dynamic earth sun relationship
    speed: 380.3 km/sec
    density: 2.7 protons/cm3



    7 sunspots, keeping an eye on AR2257

    A hit of a geometrical coronal hole present but not sufficiently large to warrant an alert.

    Auroral activity is "interesting", with some geometry present

    Interesting - watching the same types of images/geometries projected on earth too, in the plasma of the auoras.. I keep an eye on that the coronal holes plus the auroral patterns..

    There is quite a tie-in over 93 million miles.. quite an amazing field.

    some good references to that are HERE: http://astrogeo.oxfordjournals.org/c...50/2/2.31.full

    Protons are really dense and hitting

    Solar wind
    speed: 300.2 km/sec
    density: 20.4 protons/cm3

    VERY QUIET SUN: Solar activity is very low. Not one of the sunspots on the solar disk is flaring, and as a result the sun's X-ray output has flatlined. NOAA forecasters estimate a scant 5% chance of M-class flares and no more than a 1% chance of X-flares.


    Looks like 4 defined sunspots

    Radio Sun - microwave hitting the earth from the sun is UP slightly

    dual polar coronal holes, with geometry, the southernmost hole is quite large, while the mid hemisphere holes have closed.

    those lead to bursts of particles reaching the earths's geomagnetic field resulting in a bit of a bounce, and strong auroras..

    Here is a closeup:

    Solar activity


    Solar wind - speed has picked up and proton count has diminished.
    speed: 479.2 km/sec
    density: 5.0 protons/cm3

    Radio Sun - microwave levels starting to creep upwards and when the new sunspot on the mid left side of the sun appears, this should go up in intensity
    10.7 cm flux: 126 sfu

    Bz: 6.6 nT north - the north orientation closes the geomagetic field a bit, and this bounce in polarity is indicated by the K-index increasing

    NEGATIVE POLARITY SOLAR WIND ALERT:

    In the solar wind flowing past Earth, magnetic fields are tilting south.

    This is the kind of "negative polarity solar wind stream" that can produce intense polar auroras.

    Sky watchers around the Arctic Circle should be alert for bright lights in the night sky on Jan. 23rd.

    Northern solar coronal holes are closing, but the southern one remains large and opened and is earthfacing.
    It is streaming particles to earth's geomagnetic field, and storms are expected through the 28th of January.

    Solar sunspots again are diminishing, down to 4 currently with AR 2268 having the most chance for activity.
    The existing sunspots are not generating excessive microwave energy to the earth.

    The coronal hole is a concern for particle streams in the next 3 days..



    This is massive and starting to spread to the equator of the sun, meaning particles will squarely be emitted to the earth.

    This is another view of the magnetic field lines appearing around the hole:

    Quote Coronal holes are places where the sun's magnetic field spreads apart and allows solar wind to escape. Streaming along open lines of magnetic force (see the arrows above), hot gas flows outward at speeds exceeding a million mph.

    A stream of solar wind from this coronal hole is expected to reach Earth in the days ahead. NOAA forecasters estimate a 55% chance of polar geomagnetic storms when the solar wind arrives

    Solar wind speed keeps climbing

    Solar wind
    speed: 710.0 km/sec
    density: 2.8 protons/cm3

    Proton count is not too high which is a good thing

    This is the ALERT interpretation:

    GEOMAGNETIC STORM: A stream of high-speed solar wind is bufteting Earth's magnetic field, and this is sparking G1-class geomagnetic storms around the Arctic Circle. High-latitude sky watchers should be alert for auroras shining through the moonlight

    Planetary K-index
    Now: Kp= 5 storm

    This is the result of the massive Coronal HOLE facing earth







    Interplanetary Mag. Field
    Btotal: 6.6 nT
    Bz: 2.7 nT south - south orientation means that solar particles will be able to easily enter the earths geomagnetic field.

    density: 1.3 protons/cm3


    sunspot count is down to 6 earthfacing

    GEOMAGNETIC STORM ALERT: A stream of high-speed solar wind is bufteting Earth's magnetic field, and this is sparking G1-class geomagnetic storms around the Arctic Circle. This morning in Alaska, the auroras were bright enough to see through almost-full moonlight:

    things feeling odd/tense? Maybe the above is the reason why..

    Sitting on plasma 'eggs'

    Over the last week there has been a plasma thread sitting suspended over the SW edge of the sun. It is taking it's time growing towards the equator.. As the Sun rotates, it could in another few days be square on aligned in earthview.


    Should the thread disassociate (split or break apart), it could send out massive earth sized particle packages into Earth's geomagnetic field, and of course potentially damage satellites, and/or the international space station..

    This thread is estimated at 400,000 kilometers long.

    Solar Wind and proton density is currently 'normal'.

    Solar wind
    speed: 403.1 km/sec
    density: 4.5 protons/cm3



    3 predominant sunspot groups are being reported, but it looks like there are at least 3 more not being reported for some reason.

    Solar microwave levels are remaining slightly higher than normal, but that could be due to one predominantly active sunspot, AR 2277 which is starting to move towards rotating out of view. When it rotates off viewing position, the solar microwave levels should diminish.

    Radio Sun Microwave Emission
    10.7 cm flux: 145 sfu

    Bz: 0.4 nT south allowing for particle entry into the geomagnetic field

    Coronal holes, not particularly strong but some small ones with geometry are starting to form.



    In the bottom southwest corner, one can see the new coronal hole formation, with the similar characteristic of the double peaks showing up towards the equator. To the left snakeing upwards is the plasma thread.

    Looking at the thread it could potentially expand uptowards the northern pole.. That would make the thread double in length and energy potential during a separation/breakup could then become massive...

    The solar polar coronal hole remains, but is traveling out of direct earth facing view.

    Auoral activity, has been moving a lot further south, across the Yukon in Canada, and across mid to northern Alaska:

    The thread/string on the SW corner of the sun continues to grow as the coronal hole to the right of it.



    Interplanetary Mag. Field continues to be southernly allowing fo particle influx into earth's geomagnetic field.
    Btotal: 9.0 nT
    Bz: 4.4 nT south

    Size of the string: If the thread were removed from the sun and stretched out, it would easily reach from Earth to the Moon.

    It could also be wrapped around the circumference of giant Jupiter many times over. This should be watched.

    The Geometry is very clear in this image showing the sizes:
