oz 2-53 suffice to check and revise current theory and provide a reasonably comprehensive understanding of high altitude fireball phenomenology. 2.2.9 Addendum. Program 17. Teak, Orang? A variety of electromagnetic sisnals were recorded on both shots. No analysis has been atteipted yet. 2.2.2 and 2.2.10 Addendum. Programs 10 and 18, Orange Objectives. Objectives were the same as for Teak. After failure to obtain early fireball core data from Teak shot, an attempt ~s- made to obtain such data from Orang? althouzh one had to éxpe. very high reaction rates, DELETED DELETED : Many instruments were vwrerefore pointed at Theburst location and were set for highest possible time resolution. Unfortunately the shot was fired under deteriora ting weather conditions and at the critical time the recommendation of the responsible program officer to hold or to delay the shot was not accepted, (much to the astonishment of the projects, which had been made to believe that clear visio: from Johnston Island was manfdatory for the shot). At shot time the altostratus cover over the Island was 8/10 (not 5/10 as officially reported for the Johnston Island area), resultir in a mean diffuse optical transmission of only 6%; the transmission for the collimated observation channels was even less. Instrument and station performance record was good. egpienid Not one single NRL operated instrument failed; at the LASL end 57 oscilloscope channels recorded out of a possible 61 and Bowen and spectrograph channels operated. eee Tele pa qu a4 = PACE o>
