(ap:) APRIL- 20 the disturbance of the geomagnetical field ( PAI indicates minor activities may occure on Earth during April 21, such as :

-EM disturbances* on electronic devices-
-low - medium disastrous Earthquakes-

Due to an possible Earth directed CME and a large coronal hole rotating into Earth direction, new activities must be expected from April 22 on! Check again for updates tomorrow!

April 20: A disappearing filament in the southeast quadrant late in the day may have produced a partially Earth directed CME (pending further analysis).

No obvious coronal holes are currently in or near Earth facing positions. A large coronal hole will begin rotating into view at the southeast limb within 2-3 days.

NEW GEOMAGNETIC HAZARD

solen.info/ April- 6- 2011:( read also right side)

The geomagnetic field was quiet to major storm on April 6. Solar wind speed ranged between 473 and 578 km/s.

A disturbance was observed starting at SOHO near 08:55 UTC (and peaked geomagnetically during the 13 to 16h UTC interval with an ap of 111). This was likely the arrival of a large CME observed in association with a long duration event involving region 11176 late on April 2 and early on April 3.

SUN flares :A total of 3 C flares were observed during the latter half of the day, all from a source just behind the northeast limb.

alien homepage/ notice: the CME> not registered by the NOAA might have to do with the overall high CME and flare activity on the Sun . Though just one of these was directed towards Earth, the " coronal hole "described by solen.info might be a negative " gravity" increase side effect by that high activity

 

Scientists now declared to have discovered new " elementary particles"

one CMEs not directed to Earth might cause minor effects

solen.info ( report was unfortunataly late) ; March- 31-A geomagnetic disturbance has been in progress since 9h UTC. The source of the disturbance is uncertain, While a coronal hole is a possibility, solar wind density has been high since the onset of the disturbance. SOHO/MTOF recorded a quick increase in solar wind speed, density and thermal velocity near 16h UTC.

                   
 

 

 

possible means: any heavier earthquake is possible- but not sure! - probable means : there will be any heavier Earthquake with high probability
