    X class-Solar Flares

    Just saw on tv that there have been some huge solar flares seen today. X class flares, thats supposed to be the largest type apparently. What can we expect to notice here on earth. I have heard that the Northern lights may be spectacular.

    Probably not too much. Satellite operators and the electrical grid operators watch these events closely, and are usually well prepared to deal with them. There may be some communication problems in HF radio bands during certain times.

    Auroras are indeed a possibility, but the conditions must be just right for them to occur, especially at lower latitudes. As of right now, this last proton flare created a CME that's predicted to arrive at Earth's magnetosphere sometime tomorrow or early Wednesday. That would be the time we'll have an idea if Auroras will be visible, or if we get into geomagnetic storm conditions.

    After doing a bit of googling i've kinda come to the conclusion that these events are not exactly rare. They seem to happen like 20 times per year, is that right?

    That may be right. As a flare has some specific direction, what is rare is that one hits the earth, giving us northern lights, radio problems and power outages.

    That's a point the Twienkies usually don't tell when they say that space travel is dangerous because of the frequent flares. They are only dangerous when they have the right (means wrong) direction...

    There was an X18 - yes that "18", not "1.8" proton flare this morning from AR10486 - with a full halo CME currently in progress. Sometimes these high (X10+) flare designations get revised later, so it may increase or decrease. SEC hasn't updated their events listing since the flare occured.

    Looks like Wednesday night might be a good time for Aurora watching/photography. The CME is an almost perfect circle on the LASCO C3 images:

    According to Spaceweather.com, that X18 has been revised down to X14. That's still a heckuva flare.

    I've just added todays pic in my above posting. That 488 is appearing and growing pretty fast. Would be nice to get a good time-lapse movie with higher temporal/spatial resolution somewhere.

    Spaceweather.com and SOHO site are now both calling it an X17.2 flare- the second largest ever observed by SOHO!

    We're all DOOOMED!!!

    Working in the power industry as I do, I am excited about the flare. It is very rare for one of this magnitude, and even more rare that it would be facing the earth when occuring. I am looking forward to seeing what our power monitors pick up, if anything. I am also wishing I had a solar filter for my scope. :-?

    You don't need one- just hold up a piece of paper behind the scope, and project the image of the sun straight on to it! Make sure you don't forget and look through the eyepiece by accident though... [-X

    only is you don't value the insides of your scope, the concentrated sunlight will melt the secondary mirror and eyepeice. that is why the solar filters go over the apeture and not eyepeice.

    so don't do that. and always use a solar filter
