The conference went well; I believe I gave a good account of myself.
This week I've been taking more photographic spectra, looking for the Stark/Zeeman effect. The spectrum that I took yesterday is promising, since it shows evidence of the effect, but not conclusive proof. For that we need to see separation of the spectral lines, or - at the very least - broadening. The Hg spectrum I took yesterday shows a much lower intensity in many of the lines, which is good, because we know that our magnet is strong enough (~9000 Gauss (G) or .9 Tesla (T). By comparison, the Earth's magnetic field ranges from .31-.58G.) to affect the atoms in the mercury gas. To further search for the broadening, we will narrow the slit and increase the exposure time.
