If you have a telescope it is possible to view the Great Red Spot (GRS) as it transits across Jupiter. The spot isn’t always visible, it moves around the planet and can only be seen as it crosses the Earth facing side of Jupiter.
The spot can be seen for around two hours before and two hours after it crosses the central point on the planet (the central meridian). This gives a 4 hour window for viewing the spot, the from and to times that the spot is visible can be seen at the top of this page. IMPORTANT NOTE – you will need to check when the plant is visible within the 4 hour window to avoid disappointment. Times are normally given in UT however we have already converted these to BST.
Transit time: The GRS crosses the central meridian at: 22:00 BST
