I'm not sure about the rest of you, but I rely on SOHO to deliver data for my research. There have been times when my net connection has messed up and gave me broken data like this, only needing a refresh, but today it is either the probe itself or NASA's communications. Because some of the instruments appear to be acting normally, it looks like possible damage. Gosh I hope this is just a glitch.

 

I've been working at developing a system for predicting flares based upon the magnetic symmetries of syzygies compared to an estimate of where plasma channels may be existing inside the convection zone and how that relates to the deeper core. I've hit a few within 12 hours, such as last October 15th and January 20th, but predicted one on March 17th or 19th that actually occurred on the 7th. I have one predicted for today and have been watching the LASCO C2 as well as the EIT 304 images, both suggesting the build-up. Activity readings can be deceptive at times, so I leave them out for the most. At my own forum, and other places on the net, I've posted predictions for 2012, so it can be validated that I'm hitting some of these in advance.

 

If the EIT's are damaged, this may hinder some of our research projects :(

i'm not seeing the problem you are. is it ok now? the instruments do accumulate a charge over time that degrades the images and peridoically they do a CCD "burnout" to clear them. they usually put up a notice, though i haven't visited the site the last week or so & can't say if that is the case now. :shrug: good luck on your project. :smilingsun:

 

edit: my bad. i do see the 2 glitchy images on EIT 195 & EIT 304. might be time for a burnout is all. we have had a lot of activity lately.

LASCO C2 is a good guide for intensity of the solar atmosphere. I check it frequently. I have EIT304 on my desktop. The movie page brings it to life.

 

Could have been a number of things. It never hurts to have a link to the site hanging around.

roger. i have a thread here on the topic of SOHO that you might enjoy & contribute to. >> SOHO Page for if you like to watch the Sun :smilingsun:

WEEKEND AURORAS: Last night, April 6-7, parts of the high Artic Circle were alight with auroras so bright even the full Moon couldn't overwhelm them. In the village of Ivujivik, Nunavik (Canada), many of the luminous formations reminded onlooker Gilles Boutin of flowers:

 

That was from today's space weather.

 

I'm glad you put that link in there because it reminded me to go there.

 

For the Aurora to occur like that on the 6th and 7th, there would have needed to be at least a minor storm on the 5th, which would be the day I predicted... again :)

i wasn't sure if i had mentioned SpaceWeather.com or not; glad you're on it. i visit that site daily and the soho site less often.

 

as to a solar "storm" being necessary for aurorae, this is not the case. quoting from spaceweather's april 2nd page:

 

April 2, 2012

SPONTANEOUS AURORAS: Solar activity is low, but solar storms are not always required to make auroras appear around thee Arctic Circle. Ole C. Salomonsen photographed this spontaneous display last night over Tromsø, Norway:

...

The reason for this show was the interplanetary magnetic field, or IMF. On April 1st the IMF tipped south, opening a crack in Earth's magnetospherre. Solar wind poured in to fuel the auroras. (So the sun was involved after all.)

Cool. I learned something today. I was unaware of the spontaneous auroras. Watching LASCO C2 for the few days prior (at the SOHO site you can go to the "movies" section and count back as many days as you pretty much like) tended to indicated a flare was in progress and not a small one either. The NASA prediction is for the 10th.

 

I'd have been very discouraged if anything happened to fry that probe. It's good to see it all back in order.

my pleasure. :) you may also be interested to learn -presuming you don't already know- that we do have other instruments monitoring the sun. one is called the Solar Dynamics Observatory. SDO for short. here's the home page. >> Solar Dynamics Observatory

 

today's news from SDO:

SDO 360 degree roll

 

Thu, 05 Apr 2012

 

The Helioseismic and Magnetic Imager (HMI) instrument, one of three instruments on board NASA's Solar Dynamics Observatory (SDO), is making precise measurements of the solar limb to study the shape of the Sun.

 

Twice a year, the SDO spacecraft performs a 360 degree roll about the spacecraft-sun line. This roll maneuver allows us to remove the instrument optical distortions from the solar images taken by HMI to precisely determine the solar limb.

 

Thanks to the high resolution observations of the HMI instrument, solar scientist can measure if the Sun's sphere is changing over time as a result of the solar cycle. On April 4, 2012 SDO performed its 6th roll and the accumulated data is being studied and reviewed and will later be published in a paper.

 

the other is actually 2 satellites in a project called STEREO for Solar Terrestrial Relations Observatory. here's that page and a blurb from it. >> Solar Terrestrial Relations Observatory

Welcome to the STEREO website!

 

STEREO consists of two space-based observatories - one ahead of Earth in its orbit, the other trailing behind. With this new pair of viewpoints, scientists will be able to see the structure and evolution of solar storms as they blast from the Sun and move out through space. ...

Yes. I'm aware of both. I did pull the icons onto my desktop though. Been meaning to do that for a bit. CLUSTER is another one I need to get on the DT. I have a 19 inch monitor a friend gave me recently, so I think I'll swap that out so I have a bit more real estate...

 

Thanx.

CHANCE OF MAGNETIC STORMS: NOAA forecasters estimate a ~30% chance of geomagnetic storms around the poles on April 9th. That's when a CME is expected to deliver a glancing blow to Earth's magnetic field. The cloud was propelled in our direction by a solar filament erupting on April 5th (movie). High-latitude sky watchers should be alert for auroras. Aurora

 

And there you have it folks! That was from today's Spaceweather (Thanks for reminding me of that site Turtle. :) )

 

Next prediction on my list is for May 5th.
