The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) has been in low-Earth orbit since February 5, 2002, performing imaging spectroscopy of solar flares in the hard x-ray and gamma-ray range. RHESSI's high-resolution germanium detectors are unshielded and collect photons above approximately 100 keV from the whole sky. By using the Earth as an occulter, we can make a background-subtracted spectrum of the inner Galaxy. We see the 1809 keV line from 26Al with 11 sigma significance in data accumulated through December 1, 2002. The width of the line is 2.03 (+0.78, -1.21) keV, disagreeing with the 5.4 keV width reported by the GRIS balloon. I will present updated results on this line and discuss the status of the search for the lines from 60Fe in the Galactic spectrum. This work is supported by NASA contract NAS5-98033.
