This year the Sun is on its way to the dullest part of its 11-year activity cycle; solar minimum is due in late 2006. But that doesn't mean nothing's happening! Right now the Sun is displaying a big, complex spot several times larger than Earth.
Sunspot 10756 (or "756" for short) is visible to the unaided eye through a safe solar filter or by the projection method. As of May 4th, it had rotated well past the middle of the Sun's face to the Sun's western side. In the next couple of days it will move closer to the western limb and become more foreshortened.
A solar-filtered telescope shows rich detail in the spot's complicated umbra and penumbra. For more about watching the doings of our home star, see our solar observing section.
