Red Spot Junior

Red Spot Junior, or Oval BA, is a spot on Jupiter first observed in 2000 by the Hubble space telescope. The spot is formed by the storms on Jupiter and is the result of the merger of three smaller spots. Oval BA had a whitish colour in November 2005, before slowly turning brown in December 2005, then red in February 2006. The spot is visible to amateurs using a 28 cm diameter telescope fitted with a CCD camera; nobody knows whether this little brother of the Great Red Spot will remain as it is, or, like many other spots observed in the past, it will turn white again.
