A8 SOL · DETECTOR-SPACE ORIENTATION EVIDENCE
SEP 18 2026 · EPOCH-7

A8 STAMP
2026 · WEST 6–8 · MERCURY · WATER

STATUS
QUALIFIED DETECTOR-SPACE SOL TRACK WITNESS

PURPOSE
Preserve additional physical Sol data for building the A8 orientation
relationship from repeated Nature observations.

This evidence does NOT declare a finished Year Angle.
It does NOT retune Core20 or any physical carrier.
It records what the telescope/detector actually saw.

OBSERVING CONDITIONS
Cloud interference is present.
Cloud-obscured / poor-limb frames are rejected from the primary fit
rather than averaged into the orientation result.

PRIMARY ORIENTATION FIT
source · first recording
accepted interval · 8.0 .. 104.0 s
accepted limb frames · 193
accepted limb-edge points · 15,440

detector X motion · +23.8610 px/s
detector Y motion · +1.0950 px/s
screen convention · +Y is downward

track speed · 23.8861 px/s
track angle · +2.6274 degrees screen-down from screen-right

fitted solar radius · 1527.5831 px

limb-fit residual
median · 1.1137 px
90th percentile · 2.8964 px

INDEPENDENT WINDOWS
8–32 s    · +2.5390 degrees
32–56 s   · +3.0881 degrees
56–80 s   · +2.5207 degrees
80–104 s  · +2.0410 degrees

The repeated windows support a detector-space solar drift direction
near +2.6 degrees. The spread is preserved rather than hidden.

SECOND RECORDING
The second recording contains another Sol limb passage but is
substantially more cloud-limited.

It is retained as SUPPORTING PHYSICAL EVIDENCE.
Its less-stable vertical component is not used to retune the primary fit.

SEMANTICS
Nature is the reference.

This result is DETECTOR-SPACE ORIENTATION EVIDENCE.

It is not yet:
- a finished A8 Year Angle
- a Meridian-0 declaration
- permission to retune Core20
- permission to alter the physical carrier rate

Future Sol / Mintaka observations can be compared against this
detector-space witness to refine the orientation relationship.

NO UTC / HOST / BROWSER TIME IS USED AS A8 AUTHORITY.
