When SDO looks for a comet it does not see the dust and ion tails seen in a comet far from the Sun. We see oxygen ions, oxygen atoms with some electrons stripped off, glowing when they are hit by the hot electrons in the corona. The AIA telescopes normally look at iron ions, but the enormous amount of oxygen that comes off a comet allows that element to emit brighter for a while after the comet passes. The images we showed yesterday were our best guesses for which AIA passbands would show bright emissions from Comet ISON as it flew past the Sun. They are the passbands that showed Comet Lovejoy in December 2011 and the earlier comet in June 2011.
Seriously though, this still leaves the problem with the lack of movement of the sun flares.
Can anybody weigh in on this?
Since 1 August 2010, EIT has reverted back to its original observing mode, taking images of the Sun only twice per day.

No I don't think the entire organisation was in on it, I don't think anyone was in on it.
During the live feed, they had two of the leading scientists what built and work with the SDO commentating.
If anyone was going to know if something was up with the feed, it would be them and they showed no signs of being in on it, rather they showed signs of slight embarrassment and disappointment due to the comet not showing up.
Like I just said, Lovejoy showed up wonderfully and they were expecting the same thing to happen for ISON.
So why ISON and not Lovejoy?
By the way, it takes no effort at all to make NASA look bad, they doing a marvelous job all by themselves.
