We are not done yet! A 2nd X-class solar flare in less than 24 hours. This one is even larger than the first one, measuring at X2.8. 

This one is also not Earth directed.

The region that has produced 2 X-flares (X1.7 and X2.8) in roughly the last 24 hours, has produced another X-flare moments ago larger than the previous 2. It's peaked at X3.2..

SOLAR ACTIVITY SURGES: A sunspot on the sun's eastern limb is crackling with powerful X-class solar flares. Just-numbered AR1748 announced itself during the early hours of May 13th with an X1.7-class eruption (0217 UT), quickly followed by an X2.8-class flare (1609 UT) and an X3.2-class flare (0117 UT on May 14). These are the strongest flares of the year so far, and they signal a significant increase in solar activity. NOAA forecasters estimate a 40% chance of more X-flares during the next 24 hours.http://www.spaceweather.com/

Monster radiation burst from sun.

[cooling climate]

Most of the activity on the sun the last couple of days has been directed away from the

Earth with no more than moderate activity directed at us.That is not to say that things will

not change as the active region on the northeast limb moves into a more geo-effective

position over the coming days.

CHANCE OF FLARES: NOAA forecasters estimate a 50% chance of X-class solar flares and an 80% chance of M-class solar flares today. The source would be active sunspot AR1748, which is turning toward Earth. http://www.spaceweather.com/

POSSIBLE CME IMPACT ON MAY 17: A coronal mass ejection (CME) hurled into space by the X1-flare of May 15th might deliver a glancing blow to Earth's magnetic field on May 17th. NOAA forecasters estimate a 40% chance of polar geomagnetic storms when the cloud arrives. High-latitude sky watchers should be alert for auroras. http://www.spaceweather.com/

MINOR STORM: A minor (Kp=5) geomagnetic storm is in progress following the glancing impact of a CME during the early hours (~0100 UT) of May 18th. High latitude sky watchers should be alert for auroras. http://www.spaceweather.com/

Paul Zizka from Banff, Alberta sends us this stunning image he captured very early this morning during the minor geomagnetic storm. Thanks for sharing!

A flare just peaked at M1.7, and was located off the east limb around returning region 1731.

Solar activity seems to be on the up-tick once again after a short lull, Some strong C flares early'er today..

 

 

 

WEEKEND CME STRIKES: Over the weekend, a pair of CMEs hit Earth--one on May 18th (0100 UT) and another on May 19th (2250 UT). The impacts, especially the first one, rattled Earth's magnetic field and sparked Northern Lights visible as far south as Colorado. Some of the brightest appeared over Cape Cod, Massachusetts, where photographer Chris Cook took this http://www.spaceweather.com/

A nice M7.3 flare earl'er from sunspot 1745. producing a near halo CME. With this being earth facing, it should produce solar activity around the 25th May.

SUBSIDING RADIATION STORM: A solar radiation storm in progress around Earth is slowly subsiding. It currently ranks S2 (moderate) on NOAA storm scales, which means that satellites in Earth orbit could experience "single event upsets" in their electronic systems. The radiation storm is also a source of noise in spacecraft cameras, giving their images a snowy appearance. http://www.spaceweather.com/

STORM WARNING: A CME propelled into space by the M5-class explosion of May 22nd is expected to deliver a glancing blow to Earth's magnetic field on May 24th. NOAA forecasters estimate a 55% chance of polar geomagnetic storms when the cloud arrives. http://www.spaceweather.com/

Aurora Watch (BGS) now also reporting we'll be moving through the edge of a CME in the next 36hrs and a storm is possible.

Looking good for Scotland tonight...

Currently a kp5 if in north of Scotland... Have a look out.
