SUMMARY Over 30 lines from the v=3{0, 4{1, 7{3 and 8{4 vibrational series of the hydrogen molecule have been observed from = 7600{8800 A in the reeection nebula NGC 2023, originating from levels up to 41,000 K above ground. This is the rst time that H 2 has been observed in 1 the optical CCD regime and these are the highest excitation lines from the ground electronic state that have yet been de...
