Progression of Bird's Strike.
Many amateur astronomers have imaged the impact scar on Jupiter since it hit Jupiter on July 19th. ALPO and Jupos members have been very active with this. Hans Joerg Mettig from Jupos.org in Freiburg Germany converted a number of these images into a polar projection using WinJupos. I have taken the liberty of putting these in an animation to show how the scar has progressed between 7/19 and 8/8. Thanks to all that contributed to this! I have to say that none of my images made it into this animation.

The animation has been updated today (Sept 2) and now includes images from 7/19 up to including 8/31 with very few gaps in days covered. The animation is made up of images of: Anthony Wesley, Damian Peach, Donald Parker Joel Warren, Paulo Casquinha, Stephen Keene, Mike Salway, Michael Phillips, Trevor Barry, Christopher Go, Tomio Akutsu, Stefan Buda, Brian Combs, Fabio Carvalho, and Zac Pujic.
