Details:
The Sun may appear 'blank' in regular broadband white light as it approaches the 'quite' period, or solar minimum, but at specific wavelengths across the visible spectrum there is much more to be seen. Using narrow-band imaging, such as hydrogen alpha at 656.28 nm, hidden structures and levels of activity can be revealed that would otherwise be lost in the glare. This is a close view of a current active region on the Sun which as imaged using a modified 250mm RC telescope fitted with a hydrogen alpha filter and protective energy rejection filter. This wavelength reveals beautiful and delicate ribbons of plasma shaped by the action of magnetic forces in the Sun's atmosphere. Quiet sun? I think not.
