Junction 14-A — Prior-Art Note
Working note prepared by Senior Signal-Physicist Ingrid Halvorsen for the array's institutional archive, in response to ISNI's standing request for prior-art on the Junction 14-A reference frame, dated late 2141. The note was filed before the Junction 14-A survey mission departed Earth. The physicist who wrote it had no operational interest in the mission.
1 · Reference
ISNI Office of Vessel Operations standing request 2141-OVO-PR-09, received 12 November 2141, requesting Svalbard's institutional record of any prior detection events on the spatial co-ordinates designated Junction 14-A. The array's catalogue carries seven entries against those coordinates between 2089 and 2138. They are summarised here.
2 · Catalogue Entries
| Date | Class | Notes |
|---|---|---|
| 02 Jun 2089 | BG-FIELD | Background-field calibration. No anomaly. |
| 17 Sep 2098 | BG-FIELD | Background-field calibration. No anomaly. |
| 11 Jan 2112 | PERTURBATION | Transient. Filed as instrument drift. Re-flagged 2127. |
| 09 Aug 2120 | BG-FIELD | Background-field calibration. No anomaly. |
| 23 Mar 2127 | PERTURBATION | Phase signature consistent with 2112 entry. Re-classified RESONANCE-CANDIDATE. |
| 14 Oct 2133 | RESONANCE-CANDIDATE | Persistent signature at 1420.41 MHz ± 0.02. Confirmed Seam. |
| 04 Nov 2138 | JUNCTION (NEW) | Catalogued as Junction 14-A. ISNA reference frame established. |
3 · Observation
The array's record shows two unexplained transient phase signatures (2112, 2127) preceding the 2133 confirmation by eighteen and six years respectively. Both were filed at the time as instrument drift. Both are, on the basis of the present re-review, consistent with one another and with the eventually catalogued junction. The institutional record has corrected these classifications.
For the purposes of the ISNI request: the array has no record of any phase signature at Junction 14-A's coordinates between 2138 and the date of this note. The junction is, by the array's record, quiet.
— quiet at this frequency. The array does not look at the harmonics, which ISNI does. The array does not look at the secondary-band wings, which the secondary stack does. If ISNI wishes to know whether 14-A is quiet at every frequency, ISNI should ask itself.
4 · Recommendation
The note is filed for ISNI's reference. No operational recommendation is provided. The vessel mission departs on its own schedule, by its own institutional authority. The array's institutional position is, as always, observation without intervention.
The note is dated four months before NV Erika Magnusdóttir arrives at Junction 14-A. The vessel's First Communications Officer is married to the physicist who wrote it.
