Some factors that go into this equation:

Universal Time is 14.3858333333333 in decimal hours.
The Julian date was 2458843.50166559.
The sun’s ecliptic longitude was 274.538593236156 degrees.
Its mean anomaly was 352.0355347541 degrees.

These calculations incorporate the switch to the English New Style (N.S.)—i.e., Gregorian— calendar after Wednesday, 02 September 1752; the next day became Thursday, 14 September, skipping eleven days. (Please also note that, while fairly accurate, these calculations remain a bit buggy.)
