      • IMPACT IN JUPITER (19th July 2009)

        Images obtained by Anthony Wesley from Australia showed a new dark spot in Jupiter’s South Polar Region whose morphology differed from “normal features” in Jupiter, strongly suggesting that it was caused by a cometary or asteroidal impact. This was soon confirmed by other observations from telescopes all around the world.

        The dark spot was originally located at 303º ± 3º longitude in System III and latitude -56º ±1.2º. The dark spot had initially a longitudinal size of 5º and a meridional size of about 2.2º. The impact site seems similar to the intermiate size impacts during the SL9. The impact debris has been evolving in Jupiter's atmosphere dispersed by the winds.

        Observations: Observations in the visible are now more difficult to pursue due to the strong spreading of the initial impact by the jovian winds. Still the main impact site should be observed at longitude=300º System III as a very elongated polar feature. Observations in methane filters may still show the feature as a white strip and they will help to constrain the altitude of the impact debris in the atmosphere of the planet.

        The next meeting will take place during the Division for Planetary 
Sciences meeting in Orlando (USA) (http://physics.ucf.edu/DPS07/)
on Monday October 8, from 6 PM to 8 PM, at Rosen Centre (Salon 13).

      • New user interface called PVOL for the IOPW images 
        Because of the new IOPW interface/tool requirements, we will need that all 
submitted images adhere to some convention:
  1 - If possible, only 1 image (jpg, gif, png) in each file.
  2 - The filename must follow some rule to be processed quickly.
      We largely prefer that you use the one that we propose at
      PVOL >> Required Formats  (see the menu in the PVOL page).
  3 - Each contributor will be accepted by our site and assigned a two or
      three letter ID that will be used to identify his/her images. In
      addition, it will be possible to add/edit the own images comments.
  4 - To get a qualified ID, please register in our system. Contributors
      from previous apparitions are already registered and do not have to
      do it again (check your code at PVOL >> Users >> Contributors).
Failing to fulfill these requirements involves the manual processing of
the files, and that increases remarkably the time needed to make available
the image at the IOPW site.

In a near future it will be possible for the contributors to upload their 
images directly.

Older IOPW pages will be keeped but not updated. You must use PVOL instead.
      • IJW operations transferred from New Mexico State University to the Universidad del Pais Vasco 
        Starting on November 3th 2004, the Jupiter images repository of the IJW is held 
in the hosts of the Universidad del Pais Vasco, as all the other planets images.

Submission of images by contributors must be addressed to the IOPW-atmospheres 
e-mail address (iopw@lg.ehu.es).
