A lawnmower has been blamed for wrongly triggering sensors that predict whe= n the Northern Lights will be visible in the UK.

A red alert issued via the Aurora Watch mailing list was withdrawn=  after sensor readings were found to be "spurious".

An investigation revealed a lawnmower had got too close to one sensor, trig= gering a "massive spike" in data.

Aurora Watch said it was looking into ways to avoid the incident being repe= ated.

The bogus alert was issued during the afternoon of 23 August, after a magne= tometer at the University of Lancaster recorded a surge in geomagnetic acti= vity.

Trim grass

Aurora Watch is run by scientists at the university and takes readings from= lots of magnetometers to work out when the aurora borealis will be visible= across Britain.

The project draws on magnetometers in Lancaster, Aberdeen, the Faroe Island= s and further field.

The alert was withdrawn four hours after being released as it emerged only = one sensor had recorded the spike in activity.

A later update posted to the Aurora Watch webpage said an investigation had= revealed that a groundskeeper using a "sit-on mower" to trim gra= ss had been driving too close to the sensor, prompting the spike.

"We'll work with the facilities team to try and avoid an incident such= as this occurring in the future," said the scientists.

They explained any metal placed on the instrument or machinery operating ne= arby could trick it into recording more activity than was actually present.=

Readings from the Lancaster sensor were not typically used to trigger alert= s, they said, but problems with the main sensor in Aberdeen on 23 August me= ant it had become the lead monitor.
