A very nice image from Florida.
Real Time Images: The Very Latest from SOHO
SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind.

.......and as you would expect, our Star is hot, bright, dynamic, and sometimes quite violent.
At 93 million miles away, we are ideally placed at a point where the Sun provides just enough warmth and energy essential to our living planet, Earth.
At only 93 million miles, the Sun is close enough for us to view it's surface thru a relatively inexpensive scope from the comfort and relative safety (Sunscreen please) of our backyards on a clear and warm day.
What! Astronomy during the day? Lunt Solar wants to show you how.

Prominences:
These look like eruptions from the edge of the Solar disk. Prominences can be small spikey looking details, or large cloud-like detail with fine feather-like features.
They are, in fact, ionized Hydrogen-alpha emissions being projected from the linb.
Prominences are anchored to the Sun's surface in the Mesosphere, and extend outward into the Sun's Troposhere.
They typically measure many earth diameters.
Filaments:
These are strin-like features on the surface of the Sun.
At high resultion they take on a 3D effect due to the coller aspect of the suspended filament contrasted against the bright, hotter Sun.
They are actually prominences being viewed against the surface.
Spicules
A Spicule is a dynamic jet of gas about 500km long.
They move outward at about 20km/second thru the Chromosphere.
Father Angelo Secchi of the Vatican Observatory discovered them in 1877.
The Chromosphere is entirely composed of Spicules. These features can be seen as "fur"around the edge of the disk.
