By papal decree 1582 OCT 4 was followed by 1582 OCT 15. The drawing in question were made well after that but non-Catholic countries (including Britain) did not accept the change until years later so at the time the drawing was made it was 1609 JUL 26 by the artist's Julian calendar but 1609 AUG 06 on the Gregorian calendar.

One of the articles mentioned that the dates recorded by Thomas Harriot were using a different calendar than the current one (Gregorian vs. Julian or something like that), so the dates are 10 days off. I don't remember which way though.
