In the spectra we found 532 emission features, among which 459 lines from H, O, Na, C2, C3, CN, CH, NH2 and H2O+ were identified. The intensity of sodium emission lines at 5890 Å and 5896 Å on April 22 increased about 5 fold compared to that recorded on March 26 and 28. The intensity ratio Iλ5577/(Iλ6300+Iλ6364) of [O I] is consistent with the formation of excited O atoms from the photodissociation of H2O.
