"LOOK-NOW"---3 Days of Darkness Approach! NASA Stereo Behind HI1: 12/21/2012 it All Goes Dark!

Surely the image conversion process is automated with fixed parameters to ensure consistent image quality. However, the darkened images are all at much lower resolution, suggesting some sort of change to either the raw image or to the conversion process. Can you explain this?

Processing artifact from the background subtraction they're using. They usually average a previous day's images together to create a calibration image which is subtracted from the latest image so that they can elminate the glare from the sun and see the tenuous heliosphere. They only update the calibration image every so often, and as time passes it may become less and less appropriate compared to the actual glare that's present and how the CCD is responding to the light. In other words, the calibration image is currently subtracting too much.

There isn't really a "dark" region there, it's actually quite bright and if you don't compensate for it and try to just adjust the levels of the raw unprocessed beacon image to match the JPGs present online you end up blowing out the glare which is what you see with the large white region on the left side of the image:

It seems like the calibration image they're using for the non-BEACON images is much better right now (high quality low compression versions of the same images), which is why if you go back a few days the problem vanishes instantly. Once you step forward one image into the BEACON images the problem with the calibration frame appears.

In a few days when you check back at the stereo site, the beacon JPGs will be replaced with full resolution JPGs from the non-BEACON versions, at which time the "black region" will probably either be greatly reduced or gone altogether. Standard non-BEACON images have to be processed from scratch so just because there's a problem with the BEACON processed version does not always mean there will be a problem with the full res version a few days later.

hey astro, do you think anything will happen with this alignment tomorrow? anything unusual that is?

cheers.

No, but I'll be watching/broadcasting until after the moment of solstice tomorrow morning.

what here on glp?

Beacon vs non-beacon image data. Beacon image data always provides the latest realtime look (but they're highly compressed and low resolution to enable relatively small dishes to receive the files in a reasonable time at a low bitrate, thus amateurs actually provide some of the coverage to receive the beacon data and forward it on to NASA), the non-beacon copies of the images are much larger files and have to be downloaded at a reduced rate (using larger receivers on the deep space network) so they won't appear for a few more days at which time they will replace the old beacon JPG versions. Both versions are archived in their original raw unprocessed form via FTP. Each version has to undergo its own processing. Sometimes the calibration image being used for one version is better than the calibration image being used for the other.

People always claim shit is hiding in Stereo, yet nothing ever appears. Nothing is there, they are artifacts from the imagining systems, nothing more.

Thank you. That's a reasonable explanation.

Night skies network, I'll make a thread and link to my feed when it's up.

You are literally saying that the glare from the sun has subsided beyond established non-BEACON glare-reducing image processing parameters resulting in the recent darkened STEREO images. Presumably, glare is a direct function of sun luminosity, which would mean that the sun has darkened beyond established image correcting parameters.

This begs the question: is this level of darkening unusual? If so, to what quantitative degree?

lol...astronut always ruins it for the doomtards...

Correction*

Here is what Astro meant to say. "I took this film and or image and scrubbed it like NASA till it looked presentable to the public."

thats garbage. it takes hundreds of thousands of years to oscillate up and down in the galactic "disc." Yeah...We're at the top now but it'll take at least 300,000 years to move into the rift, or the middle of the disc. [link to www.nasa.gov]


....and don't act like you know more than Nasa's Goddard Space Flight Center. RESEARCH BEFORE YOU JUMP TO WILD SPECULATIONS.

Actually you folks should realize the government and amateur astronomers (majority) will most assuredly not tell you shit of any impending disaster until the fucking thing is practically on top of you and impossible to deny. Even those amateur scientists who lock on to an impending disaster will be coerced and bullied into keeping shit on a lock until further notice.

All this will be done to avoid the unstoppable raping, pillaging and apeshit slaughter that the world will inflict on itself the moment a major impending event/disaster is incoming. You people who are stupid enough to believe that you will know in advance of some major disaster are in for a fucking rude surprise. Sure maybe you are civilized and your neighbor is civilized..but your not taking the rest of the population and pshyco athiest rapist and cut throats who are waiting for that news to come so they can hit your home and tear you to bits for a can of campbells soup you have in your cupboard...

So tell me...who the fuck in their right mind would actually BE ALLOWED to spread the truth of something like a major event...thats right..NO ONE...the government will make sure of that very quickly.

so why so supposed glare doesn't use to happen/show in several slides even if one selects starting the slideshow 2-3 months before... it seems really not 'usual'

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 355 Issued at 2200Z on 20 Dec 2012

IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be at low
levels on days one, two, and three (21 Dec, 22 Dec, 23 Dec).

IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak around 500
km/s. Total IMF reached 7.2 nT at 20/1236Z. The maximum southward
component of Bz reached -7 nT at 20/1304Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 264 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (21 Dec, 22 Dec) and at quiet
to unsettled levels on day three (23 Dec).

III. Event probabilities 21 Dec-23 Dec
Class M 05/05/05

So the millions of amateur astronomers are ALL being coerced?
