Twelve days remain before the equipment tenders close for what will be the first permanent scientific installation on the Greymoor Highlands since the meteorological outpost was abandoned in the early 1950s.

The monitoring station — approved at a cost of 195,000 florins for construction plus 48,000 per year in operating expenses — will be sited approximately 800 metres northwest of the old met outpost, above the central emission zone identified by Dr Odette Collis and Professor Elara Whitstone’s mapping work in late February. The site is accessible only by pack track from the Dunvale road, a circumstance that has complicated logistics but ensures proximity to the phenomenon the station is designed to observe.

The equipment specifications, issued on 7 March, are comprehensive: three broadband seismometers capable of continuous recording to 15 metres depth, two atmospheric gas sampling units calibrated for sulphur dioxide, hydrogen sulphide, and carbon dioxide at parts-per-million sensitivity, a meteorological mast with instrumentation at three heights, and a photometric array for continuous measurement of the glow’s intensity and spectral characteristics. Battery banks providing 48 hours of autonomous operation and an insulated, wind-rated shelter complete the list.

Tenders close 21 March. Construction is targeted for April, with the station operational by mid-May — aligning with the commencement of the deep geological survey to 250 metres, funded separately at 1.65 million florins.

The Brightening

Dr Collis, whose volunteer observations have now spanned 34 consecutive clear nights since she first documented the phenomenon on 3 February, reported on Monday that the trend she identified last week has continued.

“The central emission point is marginally but consistently brighter than it was a week ago,” she said from the ridge late Sunday evening, her 33rd night of observation. “Photometric readings over ten consecutive nights now show a trend that is difficult to attribute to atmospheric variation. It is not dramatic — not a flare, not a surge. But it is there.”

The spectral signature remains unchanged: ionised nitrogen and trace sulphur dioxide, consistent with geothermal venting through fractured rock. What has changed is the intensity, which Collis estimates has increased by approximately 8 to 12 per cent since her first observations in early February.

“The question,” she said, “is whether this represents a seasonal fluctuation — perhaps related to snowmelt and groundwater interaction with the thermal source — or an escalation in the underlying geothermal process. We will not know until we have instruments on that ridge recording continuously.”

Professor Whitstone, reached by telephone, was characteristically measured. “The brightening is consistent with an active system. Active systems do not remain static. This is precisely why the station and the survey are urgent — we need data, not speculation.”

The Miners’ Cooperative of Greymoor, whose operations lie within the same geological complex, has been briefed on the brightening. Chairman Nils Haversten declined to comment but is understood to have attended a private meeting at the Royal Institute on Friday.

The ridge glows. The tenders are open. The instruments, when they arrive, will begin to answer questions that have been asked only with notebooks and cold fingers. Until then, Dr Collis will be on the ridge tonight, as she has been every clear night for over a month, doing the work that precedes the science: the patient, stubborn act of watching.
