Collection of cameras will detect meteors

‘Fireball network’ will let scientists find impact locations faster, gather better data

Western Canada is getting a faster way to track fireballs.

A “fireball network” of all-sky cameras is being put in place to allow for automated detection of meteorite-dropping fireballs, said University of Alberta scientist Chris Herd, curator of one of the world’s top facilities for preserving and studying the space rocks.

The new system will help scientists detect fireballs as they streak across the sky. It will then triangulat­e the landing location of any meteorites that make it to Earth’s surface. Quicker sample collection means better-preserved meteorites and improved analysis.

“The faster we can get the rocks and bring them to our curation facility, the better the science we can do as a result,” said Herd, with the department of earth and atmospheri­c sciences, in a Monday news release.

The new observator­ies — provided through an Australian Research Council grant, in partnershi­p with the University of Alberta — each contain two cameras, one for video and another for taking still photos.

The observator­ies will be connected to supercompu­ters in Australia, which will analyze the data and ensure notificati­on of a potential meteorite fall area within an hour of the event.

In the next two years, camera units will be deployed across Alberta, eastern B.C., and western Saskatchew­an, with the long term goal of expanding from the Rocky Mountains to Manitoba.

“The idea in the first year is to cover Alberta,” said Herd. “We’ll place about a dozen cameras spaced about 150 kilometres apart across the province.”

Locations include Lake Louise Ski Resort, Lakeland College in Vermilion, Athabasca University, and the University of Alberta’s own Miquelon Lake Research Station.

The most recent camera installati­on took place last month at Vermilion’s Lakeland College Renewable Energy Learning Centre, ideal for monitoring thanks in part to its dark skies.

Western Canada’s network will be part of a larger, global one, including those in Australia, Morocco, the U.K., and the U.S. There will also be a network in southern Ontario.
