The Great White Spot is a rare storm phenomenon. Historically, it appears once per Saturnian year (approx. 29.5 Earth years), typically erupting near the planet's northern summer solstice. The 2010 storm appeared slightly early, making the next exact date a topic of ongoing research, but the 2040s are the current general estimate.
