Jupiter's Red Oval BA aka Red Spot Jr.

Four years ago, on February 25 (local time)/February 24 (Universal time),  I was planning to image Jupiter at  around 4am.  My alarm did not go off and I ended up waking up close to 5am.  I went ahead and imaged Jupiter.  Later that day, after processing the images, I noticed that Oval BA had turned red.  The rest is history.....

Last September our group headed by Dr Imke de Pater of the University of California at Berkeley used the Hubble Space Telescope to image Jupiter.  Other members of the group include Dr Philip Marcus, Dr Mike Wong, Dr Xylar Asay-Davis and myself.  We used the new Wide Field Camera 3 installed last May by the Space Shuttle astronauts.

This is a color image of Oval BA during our imaging run.  Note the small white oval following Oval BA.  This oval is now pressed close to BA or may have merged by now.   Note the Oval BA is well resolved and the swirl of the vortex is visible.  The orange ring is still there.

This image was  done under the Cycle 17 proposal number GO11559.

Disclaimer: This is NOT an official STScI/Hubble Site image release.  This image was processed by me with the approval of the group.
