incredible bursts from sun

Spaceweather says 1029 may be the biggest sunspot of 2009

Considering the number of Spotless days the Sun has had in 2009, that's not too surpising:

Spotless Days
2009 total: 232 days (79%)

But it should signal that the Sun is waking from it's slumber, and we will likely see more activity in the near future.

Following this fairly intently now. Thanks to all of you that are updating us with the current SOHO pics.

Have you ever tried to take pictures in the dark, of a very bright light, while moving really fast?

It produces much of the same effect.

I've had some weird electronic interferences here at my house today. Even my satellite feed is coming in choppy at times. Wonder if this could cause temporary or sporadic disruption in signals?

can anybody explain what we are looking at? to me it appears to be CDs up close...

but i have ZERO experience here.

i'm about to be away for a number of hours, but any explanation, or pointing in the right direction will be taken with gratitude. thanks for the help!

Holy Guacamole, that 4th image looks like the end of the world. That just happened?

I know from past experience with DTV & Dish Network, that sun spots do indeed cause intermittent reception problems.

This thread got me to thinking about what these SOHO images should look like in the event of a really bad flare. After a little research I found a short NASA movie with some good footage.

This is what the SOHO image looks like when a large flare is recorded. This event took place back in October of 2003. I'm guessing the white lines in the image are artifacts produced by the CCD/CMOS upon overload from solar radiation/magnetic flux/electrical fields, ect.

Well the Solar X-ray bursts (produced by the current sunspot) may have some effect which may cause electronic interferences.

But these X-ray bursts are not what you are seeing in the images above. You are seeing images taken while the SOHO satellite was performing it's scheduled roll maneuver. The only thing affected by the SOHO satellite rolling over, is a brief interruption to your web browsing pleasure.

Here is some more info on a serious X6 flare, which triggered a radiation storm around Earth nicknamed the Bastille Day event, on July 14, 2000:

I see what you are trying to say paroxysm.. But if that where the case wouldnt the surrounding stars have a similar effect?

As in rotating their position in the image as the Satellite rolls over?

Sure, planets too. You can clearly see either Mercury or Venus in LASCO C3, dramatically change position over a few images, as the Sat completes it's roll maneuver:

No, if im not mistaking you are saying the rays showing on the lasco c2 & c3 are just streaks from the satelite rotating. So if that where the case wouldnt the stars be streaking as well. I see the view is rotating. But I dont think its spinning fast enough to streak and the streaks arn not in a circular form from which the satelite is rotating.

Dude, they're just performing the scheduled maintenance/roll-maneuver, there is no conspiracy here . Images won't look right the rest of the day, if you want normal looking images from SOHO you will have to wait till tomorrow.

ON OCTOBER 26TH, 2009, 13:50-23:50 UT

SOHO will perform a special 360-degree science roll maneuver on 26-Oct-09 between 13:50 and 23:50 UT. The roll comprises 10 segments (10 degrees, 8 x 45 degrees, -10 degrees), after which SOHO will be back in its nominal roll attitude.
During the manuever, images and movies will also appear rotated.
The next quarterly 180-degree roll maneuver is scheduled for 7-Nov-09.

Until then you have to satisfy your sun-gazing needs with the images coming from the two STEREO satt's.

This page is cool.

I don't know what it all means, but it's cool.

Way cool.

Thanks for the link, I'm adding it to my solar science link set.

The rotation manuever will be complete in about an hour, and we'll be able to see whether the brightness is a motion artifact or not.

Do you really need to wait an hour? These are the most recent:






On the plus side, now that SOHO is fully operational again we are getting a good shot of our currently growing sunspot, which we had not seen since 11:00am this morning. Here is a good image from 11:12am and another showing from within the last hour showing how much it's grown:






Also to add, we just got another Class C1.3 solar flare in the last hour.
