    X-ray Solar Flares
    6-hr max: C9 2017 UT Jun13
    24-hr: M2 0756 UT Jun13

    Crackling activity, with a couple sunspots that have the magnetics required to evoke up to X class flares earth facing.

    IN the midst of the particle stream from the 10th's events, (3 day delay about), the electron flux is elevated as well as proton count. The proton count has been higher. (see days before) such as the second June.

    At the moment, there really is nothing spectacular going on, just some elevated levels..

    As far as coronal holes and geometry earth facing, this is about the most blank we have seen in a while, nada, zip..



    (yawn)..

    NOAA and NASA reports no earth facing coronal holes. Also, there is a potential for CME flares from the earth facing sun spots.

    There have been radio disturbances over the last 3 days from X-Class flaring (which was not primarily earth facing, but induced a bit of a glancing beam).

    Does appear to have triangular shaped coronal hole facing us. I think it looks more like a spaceship or an arrow head.

    No other warnings or watches in effect.

    We see three sunspots present with zero indication of earth facing activity (according to NOAA and NASA)

    Auroras are NILL meaning there is minimal influx activity currently. Keep an eye out from the 26th-29th for an increase in auroral activity..

    It looks like 3 coronal holes are now earth facing with expectations of additional particle streams expected.
    Update is 28-29th to reach. Aurora activity is starting to increase.

    If it got any quieter one would think we are at solar minimum...

    Analysts have declared Solar Cycle 24 a "Mini Max" because the ongoing peak in solar activity is so much less intense than other solar cycles of the Space Age. However, today's sunspot count is anything but mini. This solar cycle has totally confounded the NOAA and NASA scientists and it has violated all known predictions.. (love to tell you how that happened but you would never believe it..)

    Solar wind - Nil
    speed: 254.6 km/sec
    density: 0.9 protons/cm3

    Big sunspots AR2104, AR2106, AR2107, AR2108 and AR2109 all have "beta-gamma" magnetic fields that harbor energy for M-class solar flares.

    The coronal hole of the 5th has widened a bit.


    The particle stream is still expected to reach on the 9th or 10th..

    10th July Solar Coronal Holes earth facing - NONE

    The M6-flare of July 8th had a noisy side-effect. There was a bit of X-Ray activity (two spikes).

    It caused a roar of static to issue from the loudspeakers of shortwave radios on Earth. In New Mexico, amateur radio astronomer Thomas Ashcraft recorded the sounds: http://spaceweather.com/images2014/09jul14/static.mp3

    Solar activity is low, but the quiet is unlikely to persist. There are three sunspots with unstable magnetic fields capable of strong eruptions: AR2108, AR2109, AR2113. NOAA forecasters estimate a 75% chance of M-flares and 15% chance of X-flares on July 10th (see below for C class activity).

    Solar wind - CALM
    speed: 376.9 km/sec
    density: 4.2 protons/cm3

    X-ray Solar Flares -
    6-hr max: C1 1730 UT Jul10
    24-hr: C5 0253 UT Jul10



    Radio Sun
    10.7 cm flux: 198 sfu



    There are no major earth facing coronal holes and no major radio activity coming from past solar events - energy CALM - there are no predictions for the 3 day period of geomagnetic activity.

    M-Class flare activity is possible.

    WEAK IMPACT: A weak interplanetary shock wave hit Earth's magnetic field on July 14 at approximately 1400 UT. This is probably the overdue CME of July 9th delivering its long-awaited glancing blow. The impact did not spark a geomagnetic storm. Updates on Twitter @spaceweatherman.

    GROWING QUIET: The odds of an Earth-directed solar flare are plummeting as sunspots AR2108 and AR2109 rotate over over the sun's western limb. The departure of these two active regions leaves the face of the sun almost blank. Solar activity should remain low for the next 24-48 hours.

    Take a look at the solar wind content.. This is intensely packed with protons compared to other reports posted.

    there are no LARGE earth facing coronal holes, but there are a lot of small coronal holes earth facing, which could be responsible for the high density proton count.

    NOCTILUCENT CLOUDS: The weekend of July 12-13 brought another outbreak of noctilucent clouds (NLCs) to Europe. Across the northern reaches of the continent, skies were criss-crossed by signature ripples of electric blue. No it is not "spraying"..

    This could be due to the planetary stress fields in the planet being excited by the incoming particle stream charges reacting with the ionosphere (opposite pole mirrors in the earth).. The result is a containment field which holds the water vapor in a geometry.

The face of the sun was completely blank and the sunspot number dropped to zero. Now, however, two small sunspots are emerging, circled in this image from NASA's Solar Dynamics Observatory:

    It's certainly beautiful out there with respect to solar activity..

    QUIET SUN: Despite an uptick in the sunspot number, solar activity remains low. AR2121 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares, but so far the quiet sunspot seems dis-inclined to erupt. A significant flare this weekend would be a surprise...

    Solar wind particle intensity is up a bit..

    Solar wind
    speed: 323.6 km/sec
    density: 8.4 protons/cm3
    Solar activity remains low despite an uptick in the sunspot number.





    A stream of solar wind flowing from the indicated coronal hole should reach Earth soon.



    some pretty Aurora activity is happening..

    Solar wind proton count is NIL again,

    Sunspot number is coming back up, but these are not causing any problems. All quiet.

    Radio Sun - moderate
    10.7 cm flux: 132 sfu


    No coronal holes not even small ones which is matching the very low particle flux.

    Planetary K-index
    Now: Kp= 1 quiet
    24-hr max: Kp= 1 quiet

    Solar activity has remained LOW for three weeks now.

    Sunspots AR2126 (S10W11) and AR2127 are the only two that NOAA/NASA seems to feel have sufficient magnetic structure that could lead to flares, but are saying despite such, these spots are remaining calm and stable.
