rosetta is now well on it's way on the separation trajectory, another look at the landing site:

http://www.esa.int/var/esa/storage/images/esa_multimedia/images/2014/11/agilkia_landing_site_6_november_2014/15030613-1-eng-GB/Agilkia_landing_site_6_November_2014_node_full_image_2.jpg

Agilkia landing site, 6 November 2014
The Agilkia landing site is seen on this image of Comet 67P/Churyumov–Gerasimenko, taken with Rosetta’s navigation camera on 6 November, just days before its lander Philae makes its historic descent to the surface.
The image presented here is a mosaic of four individual NavCam frames, captured from a distance of 30.5 km from the comet centre on 6 November while Rosetta was en route to the separation trajectory from which it will deploy Philae on 12 November. At this distance, the image scale is 2.6 m/pixel, and the mosaic measures 3.7 x 3.3 km.
The landing site, covering about one square kilometre, is located close to the top of this image, above the easily recognisable, boulder-filled depression that characterises the smaller of the comet’s two lobes. Although it may not seem like it from this image, Agilkia – previously known as Site J – presented the least hazardous terrain of all the landing sites considered during the selection process.


Looking forward to the results from this.

doesn't anyone following the rosetta probe?
tomorrow is the day, the bbc has a nice article on it http://www.bbc.com/news/science-environment-29995540
including:

Key timings for landing effort (GMT)
Rosetta delivery manoeuvre - shortly after 06:00
Latest Go/No-go decision - before 07:35
Philae separates from Rosetta - 08:35
Confirmation signal at Earth of separation - 09:03
Rosetta's post-delivery manoeuvre - 09:15
Radio connection established - 10:30
First data from descending Philae after 12:00
Landing of Philae on 67P - likely after 15:30
Confirmation signal at Earth - around 16:00

now it's just past 06:00 GMT and you can watch live -> http://rosetta.esa.int/

also there was a minor problem -> http://www.telegraph.co.uk/science/space/11223537/Rosetta-mission-setback-as-landing-probe-fails-to-respond-initially.html

and another site -> http://www.theverge.com/2014/11/11/7194501/watch-esas-rosetta-land-on-a-comet

plus from that link the schedule in ET:

The ESA's livestream will begin with a press conference, and then continue for 24 hours; it will be primarily focused on Mission Control.

Here's ESA's schedule:
2PM ET (November 11th): Livestream begins with a media update. Also the first of several go/no-go decision points.
7–8:30PM ET: Two more go/no-go decisions, as the crew confirms the lander is ready for separation.
1AM ET (November 12th): The fourth and final go/no-go decision point; a final preparation maneuver.
4:03AM ET: The scheduled lander separation.
7AM ET: Expected science update/first pictures.
9AM ET: Last preparations before landing.
11AM ET: Scheduled time for landing on the comet, plus or minus 15 minutes.

you can go to sleep now and get up before philae hits the surface ;)

last entry from just a few seconds ago:

Various science instruments are being powered up on the lander. Science will begin almost as soon as separation occurs and continues during the seven hour decent.
Separation is scheduled to occur at 08:35 GMT. It will take the radio signals from Rosetta 28 minutes and 20 seconds to reach Earth and be transferred to the Rosetta Mission Control Centre, here at ESA’s Space Operations Centre in Darmstadt, Germany.
This means that confirmation of separation should be received about 09:03 GMT.


/edit

separation must have happened, now waiting another 25 minutes to get confirmation from rosetta

sorry for double post, but separation has just been confirmed by message from rosetta

I can't wait to see imagery from the surface. The orbital (10km) pics Rosetta took are pretty incredible.

here some pictures taken during the 'tense' period:



Farewell Rosetta
Rosetta’s lander Philae took this parting shot of its mothership shortly after separation. The image was taken with the lander’s CIVA-P imaging system and captures one of Rosetta's 14 metre-long solar arrays. It was stored onboard the lander until the radio link was established with Rosetta around two hours after separation, and then relayed to Earth.




Farewell Philae - narrow-angle view
Rosetta’s OSIRIS narrow-angle camera captured this parting shot of the Philae lander after separation.




ROLIS descent image
The image shows comet 67P/CG acquired by the ROLIS instrument on the Philae lander during descent on Nov 12, 2014 14:38:41 UT from a distance of approximately 3 km from the surface. The landing site is imaged with a resolution of about 3m per pixel.
The ROLIS instrument is a down-looking imager that acquires images during the descent and doubles as a multispectral close-up camera after the landing. The aim of the ROLIS experiment is to study the texture and microstructure of the comet's surface. ROLIS (ROsetta Lander Imaging System) is a descent and close-up camera on the Philae Lander. It has been developed by the DLR Institute of Planetary Research, Berlin. The lander separated from the orbiter at 09:03 GMT (10:03 CET) and touched down on Comet 67P/Churyumov–Gerasimenko seven hours later.


there are now quite a few articles on the net talking about the landing, so i will refrain from linking any other than the nasa site with the announcement and the potential to replay some to the coverage -> http://rosetta.jpl.nasa.gov/
