OB-02

Fragment Record

PHOTOGRAPH WITHHELD AT HOLDER REQUEST

Holder has not authorised publication of photographic record.

Case No.:CASE-0002
Object Designation:OB-02
Classification:OBJECT OF INTEREST — CLASS II
Registry Status:CONFIRMED
Registered:[non-linear]
Last Amended:[non-linear]

PHYSICAL DESCRIPTION

Material:The Black
Dimensions:18cm × 12cm × 6cm (approximate)
Mass:Inconsistent with volumeMeasured: 29.1kgExpected for volume: 1.6kgDiscrepancy: 27.5kg unaccountedNOTE: OB-02 has the highest mass-to-volumediscrepancy of any registered fragment.A fragment that fits in two handsrequires two people to lift.
Surface:Matte. Identical optical properties to allregistered OB fragments. No structure at magnification.
Temperature:Below ambient. Coldest fragment in the registryby consistent measurement. Its baseline temperatureis approximately 4°C below OB-01's baseline,which is itself approximately 6°C below ambient.The Lapidary does not know if coldness correlateswith mass discrepancy. It notes both.

LOCATION

Status:KNOWN
Region:Northern Europe (precise location withheld)
Holder:Identified, not disclosed

NOTES

OB-02 has produced no liquefaction events in the period of registry monitoring. Earlier provenance does not document any events either, though earlier provenance is limited. The holder inherited the fragment from an academic institution that had acquired it as a geological specimen in the mid-twentieth century. The institution's records describe it as "anomalous basaltic material, origin unknown." The mass discrepancy is noted in their records. It is not explained.

The Lapidary has attempted to induce a liquefaction event in OB-02 on three occasions using the frequency conditions documented in signal-research/FREQUENCY-NOTES.md. No event occurred. OB-02 did not respond. The Lapidary is uncertain whether OB-02 is incapable of the liquid state or whether the trigger condition has not been found.

During OB-07's fourth liquefaction event (FIELD-REPORT-0089), OB-02's temperature dropped 1.1°C. Duration of temperature change matched duration of OB-07 event exactly. This is the only documented response from OB-02.

LIQUEFACTION EVENTS:0
ACTIVE MONITORING:YES
CURRENT STATE:SOLID
