Incoming CME from the Sun to glance Earth on May 14th

May 12, 2012SPACEIncoming CME (UPDATED): On May 11th at 23:54 UT, a coronal mass ejection raced away from the sun faster than 1000 km/s. The fast-moving cloud will deliver a glancing blow to Earth’s magnetic field on May 14th around 14:30 UT, according to a revised forecast track prepared by analysts at the Goddard Space Weather Lab. Mars is also in the line of fire. –Space Weather

    What was the magnitude of the CME? It doesn’t say on either…


  2. Jessica says:

    Does anyone know exactly what a “glancing blow” means?


  3. What exactly does that mean? What will be the results of this?


    • Steve says:

      Depending how the flare is charged, positive or negative, has an effect on the planets magnetosphere. Also, think of the planet as a microwave oven, and the incoming CME as someone switching it on for a few days. It adversely affects the movement of the plates, what we think is solid land mass(the Earth’s crust) is floating on the under layer (the mantle) and also rising internal core temperatures as a pressure cooker, released through volcanoes.
      It’s a build up effect, no single flare will cause catastrophe.

    SWA is a flexible, turn-key, Web-based dissemination system for NASA-relevant space weather information that combines forecasts based on the most advanced space weather models with concurrent space environment information. iSWA is customer-configurable and adaptable for use as a powerful decision-making tool. The system offers an unprecedented ability to analyze the present and expected future space weather impacts on NASA’s human and robotic missions.

    Yamkin, Please, what is your warning? I don’t understand. What information are we missing?

    245 MHz bursts, geomagnetic K index of 4, are not unusual. Copies of today’s (May 16 9:20 P.M. E.S. USA time zone) reports and one gm K 4 warning follow my post. The reports and warnings are prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. and are available to the public. This is a link to subscribe for various solar weather products. There are also tutorials , to explain , in lay terms, what (well, some of) it all means.

    SDF Number 137 Issued at 2200Z on 16 May 2012
    IA. Analysis of Solar Active Regions and Activity from 15/2100Z
    to 16/2100Z: Solar activity was low. Region 1476 (N13W73) produced a
    few C-class flares while continuing to decay. Regions 1482 (N13E10)
    and 1484 (N09E38) also produced a few low level C-class events. A
    pair of CMEs associated with apparent filament eruptions were
    observed in LASCO C2/C3, but neither appear to be earth directed.
    IB. Solar Activity Forecast: Solar activity is expected to be very
    low to low for the next 3 days (17-19 May).
    IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z:
    The geomagnetic field was mostly quiet. The greater than 2 MeV
    electron flux at geosynchronous orbit reached high levels during the
    IIB. Geophysical Activity Forecast: With the exception of an
    isolated unsettled or active period early on day 1 (17 May) from an
    expected solar sector boundary crossing, geomagnetic field
    conditions are expected to be mostly quiet throughout the period
    (17-19 May).

    I didn’t get to see any Aurora. Rain, rain. Much needed, and appreciated, rain.

    The CME I forecast to strike the magnetosphere on the 28th May 2012 was on time, but the consequences speaks volumes, hence Italy for example.

    The next CME strike is on the 30th May 2012. The cosmic rays will greatly influence the earth’s core resulting in more earthquakes, volcano activity.
