Beginning of the transit (I contact, external ingress): BEGG = MIDDLE - HDUR 17. Beginning of the totality (II contact, internal ingress): BEGGT = MIDDLE - THDUR 18. Middle of the transit is the instant of greatest obscuration. 19. End of the totality (III contact, internal egress): ENDT = MIDDLE + THDUR 20. End of the transit (IV contact, external egress): END = MIDDLE + HDUR June 8,2004 m Fig. 2 Summary of the Circumstances of Venus Transit of June 8,2004 By following the procedure described in the earlier section, we get the local circumstances: (All timings are in 1ST) Beginning of the transit BEGG = lOh40m (External ingress) Beginning of totality BEGGT = lO h 59 m (Internal ingress) Middle = 13 h 52m End of the totality ENDT = 16h 44m (Internal egress) End of the transit END = 17 h 03 m (External engress) We note that according to modem computation, the instants of beginning, middle and the end are respectively lOh45 m, 13 h51m and 16h5S m (1ST).
