                     Jovian mutual phenomena in 2014/15

 This autumn, Jupiter’s moons will begin a series of mutual eclipses and
occultations (mutual phenomena or ‘PheMus’).  Predictions by Jean Meeus
have been posted by the BAA Computing Section at:

Last time these occurred, in 2009, observers were able to produce the
first resolved movies of the events, as you can see on Marc Delcroix’s
web page:

Some recent views of the giant planet (all with south up):

(a) Drawing by Mario Frassati (Italy), 2002 Jan.12. Visual observers can still record interesting changes on the planet.  At this time there was notable colour in the NEB (reddish) and northern EZ (dull yellowish).  The Great Red Spot is near the right-hand edge.

(b) Image by Damian Peach (Barbados), 2006 April 14, using a Celestron-14 with Lumenera 075M camera.  Io and its shadow are crossing in front of the NEB north edge. The GRS is on the right, with streaks orbiting within it.

(c) Image by Donald C. Parker (Florida), 2006 July 10.  The newly-reddened oval BA was passing the GRS and appears just above it.

(d) Image in the methane band (890 nm infrared), also by Don Parker, taken 7 minutes after (c).  Methane images show the high cloud decks overlying the GRS and oval BA and the polar regions.

(e) Falso-colour image by Tomio Akutsu (Philippines), 2006 July 1, using a Celestron-11 with ToUcan II  camera. This combines images in methane band (red), near-infrared continuum (green), and ultraviolet (blue). High cloud decks appear red.
