Jupiter in Opposition

Jupiter will be in Opposition today, 29th October 2011. This means that the Sun, Earth and the planet Jupiter will be in a straight line, as the Sun sets in the west, the giant planet rises in the east. This gives us full night to observe the planet. From small aperture telescope to large telescopes Jupiter offers so much to observe. Jupiter will rise at 5:40pm in the beginning of the month of November and toward the middle of November, Jupiter will rise at 4:40pm and set at 5am. Towards end of November, Jupiter will rise at 3:30pm and set at 4am.
Jupiter spends all month in the border of constellation Aries and Pisces.
Here are times for observing Great Red Spot(GRS) on Jupiter. The timing is for GRS meridian transit, that is when the GRS is the middle of Jupiter's disc, the GRS can also be observed one hour before and after the transit times. All times are in IST.
