Aupiter Impact 2009

Jupiter impact, and moon transit

1rst and 20th of August 2009, Observatory Gilching

By using a 14.5-inch telescope the Australian Anthony Wesley discovered on July 19th this impact. Nothing similar was observed since the Comet Shoemaker-Levy 9 hit Jupiter in 1994. Meanwhile (8/8/09) this astronomical highlight expanded up to 6 arcsec visual (Jupiter, Dvis=45'') which has a real size on the planet of 18.000 km. The debris cloud can be observed with better amateur telescopes.

Advice: For MPEG-2 videos take VLC-Player, AVS4YOU or Irfanview etc.. it works!

Ok, let's try it also. Due to the catastrophal seeing the first observation was null and avoid. Jupiter appeared at the 27th of July in the 20" Newton like an inflamed tennis ball. The most difficulties has been the deep position max. 27° over the horizont, and the disturbances caused by the hot summer atmosphere. On the first of August the seeing was quite better but not good. The results are shown on the upper photos. 580 images were aligned and staked by Registax5 each. Video with Philips ToUcam K840

In comparision: Saturn photographed on May 2007 with the same 20" Newton: Perfect seeing - perfect shape

Jupiter moon transits

20th of August, Observatory Gilching

Here a little special about the moon transits. A double transit of Europa and Ganymede took place at 0:20 UTC / 2:20 MESZ.

The seeing was except one short pacification terrible, whereby you could only use one videoclip from twenty. From 3000 frames I selected 150 frames by hand and staked and aligned it with RegiStax5 on the Ganymede moon shadow.
