    Re: Titanic's last stars
    From: Don Seltzer

    I don't think that this portion of Boxhall's testimony has been quoted.  Some of it is a bit confusing as to exactly made the observations, but it seems that Boxhall was the one who performed the calculations.

    15545. Did you have occasion to look at the chart at all from 8 o'clock to 12?
    - Well, as near as I can remember I went to the chart room with the Captain, but the Captain put down the star position when I gave it him, somewhere about 10 o'clock. He put the position on, and I was standing close to him, but I did not take that much notice whether any other positions were put on or not.

    15546. Was that for the course?
    - That was our star position, putting down the ship's position at 7.30. But this was about 10 o'clock.

    15547. (The Solicitor-General.) I cannot hear what you say happened at 10 o'clock?
    - The Captain plotted the star position of the ship at 7.30; he put that down on his chart at about 10 o'clock.

    15548. (Mr. Scanlan.) Do you know what that position was?
    - No, I do not, but the position you have in the Court is worked from that position.

    15549. The position in which the collision occurred was worked by you?
    - Yes.

    15550. From the position indicated by the Captain at 10, I mean the Captain worked out his position at 10. At 10 o'clock he worked out the position he had been in at 7.30. Is that so?
    - No, he put down the ship's position at 7.30.

    15551. (The Commissioner.) I understood that the Captain at 10 o'clock marked the chart with the position which the witness ascertained at 7.30. Is that right?
    - He put down the ships 7.30 position on his chart.

    15552. At 10 o'clock?
    - Approximately 10 o'clock.

    15553. I understand at 10 o'clock the Captain put down on the chart the position of the ship as you had ascertained it at 7.30?
    - Yes.

    15554. Had you both latitude and longitude?
    - Yes, we had three stars for latitude, and I think three or four for longitude.

    Pitman and Boxhall said otherwise. Relevant parts of their testimony are
    quoted and referenced in my original message from 2012:
    
    http://fer3.com/arc/m2.aspx/Titanics-last-stars-Hirose-mar-2012-g18375
    
    The last paragraph, where I estimate the time and place of Lightoller's
    final round of stars, puts the observations right at the end of nautical
    twilight. That seems improbable, and is contradicted by Pitman: "We just
    took a set of them at sunset, or just as it was getting dusk, when the
    stars were visible."
