Following the detection of three small PAHs, naphthalene, phenanthrene and pyrene in dust grains collected by the Stardust probe in the environment of Comet 81P/Wild 2, we reprocessed the UV spectra of Comet 1P/Halley recorded by the Vega-TKS spectrometer. The near-UV cometary spectra were compared with laboratory spectra of anthracene obtained under laser-induced fluorescence conditions. Four main peaks coincide at 362, 367.5, 373 and 382.5 nm. This shows that anthracene is present in the innermost coma of Comet 1P/Halley and comes in addition to the previous detection of phenanthrene and pyrene.
