    2020-05-03 Sun-Venus session
    From: Tony Oz

    Hello!

    Just came back from my CN exercise.

    2020-05-03, HoE≈3meters (not so sure but definitely more than 2,5meters), Tair=8°C, Pair=757mmHg.
    Watch correction = -0h01m02,5s (i.e. WT is "fast"), Index Correction = -0°00,1' (an "off-scale" I guess). "V" - Venus, "S" - Sun.

    The "raw" data, no corrections applied:

    body; WT; HS
    V 16:01:35 42°00,8'
    V 16:02:58 42°51,0'
    S 16:03:55 12°55,7'
    S 16:04:48 12°49,0'
    V 16:06:15 41°27,7'
    V 16:07:09 41°21,3'
    S 16:08:02 12°26,2'
    S 16:09:00 12°19,2'
    V 16:10:50 40°54,3'
    V 16:11:49 40°47,0'
    S 16:12:45 11°50,7'
    S 16:13:38 11°44,1'
    V 16:15:14 40°22,9'
    V 16:16:11 40°16,0'
    S 16:17:08 11°19,6'
    S 16:17:46 11°15,0'
    V 16:18:43 39°57,1'
    V 16:19:43 39°49,6'
    S 16:20:43 10°52,5'
    S 16:21:34 10°46,7'
    V 16:22:48 39°27,8'
    V 16:23:36 39°21,9'
    S 16:24:30 10°26,1'
    S 16:25:18 10°20,3'
    V 16:26:30 39°00,2'
    V 16:27:28 38°52,7'
    S 16:28:37 09°55,7'
    S 16:29:25 09°49,8'
    V 16:30:20 38°32,4'
    V 16:31:48 38°21,6'
    S 16:32:57 09°25,5'
    S 16:33:45 09°20,0'
    V 16:35:13 37°56,0'
    V 16:37:12 37°40,9'
    S 16:38:50 08°43,0'

    I took them in alternating pairs to make the direct fix calculation more easy.
    I hope the actual weather conditions were not too far from "normal" - i.e. correctable by official Refraction tables.

    During the session I could not find Venus by naked eye, it was visible only through a Keplerian 7x scope with the correct altitude preset.

    Warm regards and the best health wishes,
    Tony
