Available β Pic spectra around the 1862 Å Al III line, with the December 6, 1997 spectrum shown in purple. Here, the strong comet absorption at all epochs makes the retrieval of an EFS difficult; however, the December 6, 1997 comet (shaded area) seems detected in this line as well (see Figs. 2, 3 and C.1 for comparisons with other species).
