Solar Activity

Real Time Solar Activity

Sunspots and solar flares are the most important thing to aurora watchers. If we have lots of sunspots, then there are good chances of some serious solar flares (M and X class) and therefore very good chance for auroras.

Using this page you can monitor the suns activity, including sunspots, solar flares, coronal holes, CME’s etc. The images are the very latest images available and are provided by the worlds leading space weather labs. Some images update faster than others, so the term real time is not strictly true for some of them, but it’s as close to real time as we will likely ever get monitoring something 149 million kilometres away (92 million miles). If you are new to all this and your not quite sure what it all means, have a read of these pages and it should start to make sense: Solar Flare wiki and Sunspot wiki

Real Time Solar Flare List

Any flares that show up on the real time images above, will show on this table within a few minutes (it takes a few minutes to determine which sunspot the solar flare originated from). The table displays the last 5 solar flares (the very latest flare will be at the bottom). Note, the flare has to have finished flaring to show up, if you see on the X ray images above that a flare is in progress, it won’t show up here until it’s done. This data is provided by Lockheed Martin Solar and Astrophysics Laboratory which is a department of the Lockheed Martin Advanced Technology Center (ATC) in Palo Alto, California.

Solar summary past 24 hours

  • 20th December

    Solar activity reached high levels during the period as Region 2242
    (S18W36, Ekc/beta-gamma-delta) produced an X1/3b flare at 20/0028 UTC.
    Associated with this event was a Type II radio sweep (900 km/s), 2300
    sfu Tenflare, and a coronal mass ejection (CME) directed off the SW
    limb. We are currently waiting on further SOHO/LASCO coronagraph
    imagery to determine if there is an Earth-directed component to the CME.

    Penumbral area within the intermediate area of Region 2242 appeared to
    be separating which separated the delta regions within the group.
    Region 2241 (S10W13, Ekc/beta-gamma-delta) was relatively stable and
    quiet over the period, however it retains a transverse delta within its
    trailing spots. Flux emergence and growth was observed in new Region
    2244 (S05E45, Cao/beta). The rest of the spotted regions were either
    stable or in decay.

    .Forecast…
    Solar activity is expected to be at moderate (R1-R2/Minor-Moderate)
    levels with a chance for further X-class flaring (R3-Strong or greater)
    for the next three days (20-22 Dec) as Regions 2241 and 2242 remain
    large and magnetically complex.
