constant, and the more readily detectable because chromospheric plage areas
traditionally are used to monitor this influence. In this context "active network" consists
of plage-like brightening extending away from active regions, as their magnetism
appears to diffuse into the quiet Sun, but constrained to follow the network boundaries.

Solar Flares: A solar flare is a violent explosion in the Sun's atmosphere. Solar flares
take place in the solar corona and chromospheres, heating plasma to tens of millions of
Kelvin and accelerating electron, protons, and heavier ions to near the speed of light.
They produce electromagnetic radiation across the electromagnetic spectrum at all
wavelengths from long-wave radio to the shortest wavelength gamma rays. Most flares
occur in active regions around sunspots, where intense magnetic fields emerge from
the Sun's surface into the corona. Flares are powered by the sudden (timescales of
minutes to tens of minutes) release of magnetic energy stored in the corona.
•
Chromosphere: The chromosphere is a thin layer of the Sun's atmosphere just above the
photosphere, roughly 10,000 kilometers deep (approximating to, if a little less than, the
diameter of the Earth). The chromosphere is more visually transparent than the
photosphere. The name comes from the fact that it has a reddish color, as the visual
spectrum of the chromosphere is dominated by the deep red H-alpha spectral line of
hydrogen.
Overview of the LS100T Hydrogen-alpha
The LS100THa is a complete Solar Telescope. The refractor-based system has a precision
aligned singlet chromatical lens with a 100mm aperture. The front singlet lens reduce half the
stray light of an achromat, it fully eliminates the possibility for on axis coma, astigmatism, de-
centering aberrations and provides with the matched collimation lens set a full spherical corrected
flat-field Solar-Telescope. The focal length is 800mm providing a ~7.25 mm image thru the 34mm
blocking filter. Fine adjustment is achieved with a Star Light Feather Touch focuser with 10:1
reduction standard. An internal etalon with tune adjustment allows for a <0.70 Angstrom
bandpass.
