Subject: X1.3 Flare and CME Likel

August 8, 2024 @ 19:35 UTC An X1.3 solar flare was detected around AR 3777 at 19:35 UTC. A type II radio emission with an estimated velocity of 1026 km/s was recorded. Coronal dimming is already evident meaning a coronal mass ejection (CME) is likely. Due to the event location facing Earth, it will more than likely be directed towards our planet. More details to follow.

GEOMAGNETIC STORM WATCH (G3): A series of three CMEs is now heading for Earth. The first two, launched by M-class flares on August 7th, are relatively minor. The third, launched by yesterday's X-flare (described below), is more potent. Striking Earth in succession on Aug. 9/10th, 11th, and 12th, the three CMEs could spark geomagnetic storms as strong as category G3 with mid-latitude auroras in the USA and Europe. ... Radiation from the flare ionized the top of Earth's atmosphere and caused a shortwave radio blackout from North America to the Hawaiian islands. Mariners and ham radio operators may have noticed loss of signal below 30 MHz for as much as an hour after the flare. Of greater interest is the coronal mass ejection (CME). Soon after the flare, SOHO coronagraphs detected a halo CME heading straight for Earth: This CME is moving faster than 1,000 km/s (2.2 million mph) and it will likely arrive no later than Aug. 11th, adding its effect to that of two earlier CMEs already en route. (Update: NOAA says "early on Aug. 12th.")The impact could push geomagnetic storm levels to category G3 (Strong) with mid-latitude auroras in the USA and Europe. |

FARSIDE SUNSPOT REPORT: The Earthside of the sun just hit its highest sunspot number (299) in more than 20 years. The farside sunspot count might be even higher. Helioseismic maps of the farside of the sun reveal vast areas of potential sunspot activity: The black blobs are sunspots so large they effect the way the whole sun vibrates. NASA's Solar Dynamics Observatory can measure the vibrations, allowing helioseismologists to pinpoint farside sunspot groups even though they are invisible from Earth. Farside activity visible in today's map is among the most widespread of Solar Cycle 25. |

Interesting. Hope they don't all go off at once. |

X1.3 CME Update August 9, 2024 @ 03:55 UTC Coronagraph imagery following the X1.3 solar flare around AR 3777 is finally available. The event was associated with an asymmetric halo CME that appears to have an Earth directed component. The main bulk of plasma looks to be heading south of the Sun-Earth line, however a shock passage past Earth will still be possible within 48-72 hours. With at least two other eruptions expected to pass Earth over the next few days, this could prolong or intensify moderate (G2) storming already in the forecast. We will have to wait and see as conditions unfold this weekend.  |

Yes. It was not a hurricane when it went by me, it was a tropical storm then. I live further inland and not close to the shore or rivers so no flooding issues here. Thanks for asking! |
