I heard Chandryaan 1 is going to track the KAGUYA impact at 1830 hrs (UTC). I'm not sure if they will share the results or pass it on to JAXA but hopefully they will put it up online. They're pretty happy to let JAXA put it up on their website - since it was their mission.
Anyway, this crash also means that India will be the only country in orbit around the Moon over the next few days.

This map follows the various predictions of the Kaguya impact point, ending with the current prediction. The ESA map is for a previous prediction.

In honor of the Kaguya impact today, here is Japan's first lunar impact, using optical navigation images from Hiten (it is only colorized, the camera was 4-bit black and white).

Ted - very nice!
Pradeep - we should perhaps qualify your comment - the only country with an operating spacecraft at the Moon now. Japan's Ouna (Vstar) subsatellite is still orbiting. And actually so is Luna 10, the first spacecraft ever put into lunar orbit, but high enough that it's thought to be in orbit still. There was an article in - I think - Air and Space - a few years ago which identified four older orbiters thought to be still in orbit - must try to find it!... Explorer 49 might have been one of the others. Hagoromo, Japan's first orbiter, is another.

The ESA report - nice to see those SMART-1 images - is not an update but a downdate... it uses the May 29 predicted location.

Ops!, I misunderstood. CST (Central Standard Time -North America) -5 GMT is different than CEST +1 GMT)! Good point!
On the other way, the impact localization was fast and it showed up that the impact zone might be on the crest of a crater. If it is true, the impact force would be strong and if it has grazed on the surface, the impact force wouldn't be lower. The IPOD pictures of Kaguya's impact had showed a very clear flash.

Just a remark: On the day after the impact, it was stated on the mission's homepage that the scientific data will be released to the public on 1st of November this year. It was mentioned right after the call for any observer who was able to capture the impact to send in the imagery for being put up on the website soon. For the life of me, I seem unable to dig out that particular article again. Anyways, I marked November 1st on my calendar. I can't wait to play around with the global elevation data...

Are those the last observations before impact? The observation date and filenames seem to suggest so. If so, these could be near-realtime downlinks from the HDTV camera on the way to the ground.
SpaceListener
Jun 19 2009, 02:34 PM
Indeed, I think that the previous post about the HDTV pictures corresponds to the last impact thru the lowering angle of ilumination inclination from the first to the last picture and the impact was at dark side of moon.

Nice craft views indeed, but what about Earth views in the next few days?
The general area in which Kaguya went down will soon be coming into (illuminated) view from our own perspective on Earth -- I wonder will we see any signs of an impact crater? As it was a very low oblique impact, ejecta patterns like we see with Messier A or Proclus...etc., may have formed. This is being very optimistic, I know, however, one never knows what might turn up -- perhaps, one of the powerful space-scopes will have a look, or, LRO might set the area down as a future target?
The illumination of the general area is expected to occur around the 23 June (New Moon on 22 June ~ 19.35) with just a sliver of a waxing crescent Moon coming through. The best time to observe would be after sunset, but then one only has an hour or so to observe anything, however, the following days 24, 25, 26 June might suit better before too much illunimation makes it impossible to detect anything at all.

Not a chance. Hubble, for example, has a resolution on the moon of about 60m/pixel. A Kaguya like impact would make a crater perhaps half the size, with an ejecta perhaps of one pixel, maybe two. Certainly indistinguishable from normal Lunar gardening without a similar 'before' image to compare it to.
LRO will go hunting for it - I'm sure.

After interpreting the infrared pictures of Kaguya's impact, it showed a more or less circle shape. Thus I seemed that Kaguya impacted frontally against a wall of a crater. If the picture shows a elongated shape or eclipse, I might deduct that Kaguya was landing and rotating until it stops after a long line.

Also, please remember that cratering studies have proven that unless an impactor hits at an *extremely* shallow angle (like less than a degree or two), it still leaves a circular crater. Ejecta can be asymmetric, but the crater itself is almost always round. I know it's counter-intuitive, but it's a fact...
