AB: Over its past two flights, the VAULT sounding rocket instrument obtained a series of subarcsecond resolution images of the solar disk. These Lyman alpha images resolve and separate structures in the upper chromosphere. The observed plasmas are concentrated in larger diameter, optically thick loops. The images taken near the limb unambiguously identify the height of the upper chromosphere in the quiet sun. An unexpected level of evolution and activity is present in the "quiet sun" at small spatial scales. The third flight of the payload will investigate the interconnectivity of the observed structures with the photosphere.
