Further Issues<br />
• Even if using more accurate extrapolation depends on resolution of<br />
magnetograms<br />
– With higher spatial resolution instruments (like Hinode/SOT) observing<br />
"ubiquitous presence of horizontal magnetic field" in very quiet Sun<br />
regions ‐ Lites et al 2008<br />
– This is an active field of research since all phenomena we observe in the<br />
Sun's atmosphere are magnetic<br />
• If we had quantitative knowledge of the magnetic field we could determine<br />
which of our models/theories are correct<br />
• <strong>Solar</strong> atmosphere is highly dynamic on a variety of timescales<br />
– From seconds to 11‐year activity cycle to even longer!<br />
• So difficult to convolve Axion flux with realistic n,B to get Axion X‐<strong>ray</strong><br />
spectrum<br />
