We present a list of interstellar absorption lines in the direction of HD 37061 in the M43 nebula. Some of the absorption lines arise from atomic excited levels that are uncommon in interstellar clouds. The excited levels of FeII are populated by fluorescence. We found a large number of H₂ molecular absorption lines arising from vibrationally excited levels. The ortho/para H₂ ratio is equal to 2.7. The H₂ rotational temperature of vibrational levels 1-5 exceeds 2000 K.
