Do you see ISON? I don't? Last c2 image did not look good. Maybe the head had moved behind the occulting disk?

The head has gone completely behind the occulting disc.

According to Spaceweather.com, the SDO AIA cameras would be pointed towards the forecasted orbit path of ISON and would be transmitting near-realtime images.

Th SDO movie I'm currently looking at is a dismal flop - it flickers - its mostly black frames with some active frames and no sign of a comet!

I watched a PBS special last night on ISON and they showed some of the AIA clips from Lovejoy.

I think at times Lovejoy was almost invisble.

I am cautiously optimistic.

From the NASA feed: SDO cant see the comet itself; too small but they are hoping to see a trail left behind by it. This is due to chemical reaction from O2 atoms interacting with the suns magnetic field.

More info and pics at the S&T ISON blog. They are reporting a big drop in brightness and not attributing it to the camera techs decreasing the exposure.




They are not mentioning the radial filtering at all, so it is possible that even Sky and Tel has missed that. We should know if the comet reappears in the C2 coronagraph, but the last C2 image does show a somewhat pointed tail and a considerable dimming of its sunward portion as it crosses the occulting disk. Clear skies to you.

Don't believe a word they say. They are basing that negativity on very little data.
