Emission lines in Low-res spectrum of T Tau

A recent spectrum of T Tau at the heart of Hinds Variable Nebula in Taurus just west (right) of the Hyades. Currently around mag 10 according to BAA VSS. It is unusual for a cooler star to show emission lines identified here as H-alpha and H-beta. The 'A' absorption line (oxygen is earth's atmosphere) well shown and a useful 'static' marker. T Tau's spectra F-K (F8Ve - KIIV-Ve) is also variable. WPO - Surrey - UK
