BackForward Variable: Solar EUV image

Full name Solar EUV image
Definition Images of the Sun in the Extreme Ultra-Violet (EUV) wavelengths in order to identify features such as filaments, active regions and coronal holes.
Measuring Units erg·(cm2 arcsec s)-1 Uncertainty Units %
Horizontal Res Units arcsec Vertical Res Units
Stability Units % (Stability /decade)


Comment: Typical measurements include narrow passbands centered at 304, 195 and 284 Angstrom. Other passbands can be considered (e.g. 175 instead of 195), but should provide equivalent information to these common passbands.
