The annual Perseid meteor shower will peak in September because of friction, which heats them to over 1000 degrees

A 60 meteors a minute average will illuminate the night sky during the peak of the annual Perseids meteor shower Friday, Aug. 12, and Saturday, Aug. 13.

As VIU astronomy professor Gregory Arkos explained to NanaimoNewsNOW, these particles of dust are from the tail of the comet Swift-Tuttle, which orbits the sun every 133 years.

The particles are very small and move very quickly. When they hit the atmosphere, they can travel at speeds of tens to hundreds of thousands of kilometers per hour, and the friction heats them to over 1000 degrees, vaporizing them.'

As the Earth travels around the sun's orbit and the comet's path is repeated every year, the regularity of this annual show is the result of the Earth passing through the comet's path in its orbit.

The weather and moon phase for the peak of the event are not ideal across the central island. The third of three supermoons this year will occur over the weekend due to forecasted showers.

The best show is likely to come Sunday and early next week if Friday and Saturday don't work. Arkos suggests going out late, after the sun has gone down, and giving plenty of time.

“The odds of seeing one aren't very high if you go out for five minutes”. Meteors don't happen regularly, they just appear from nowhere. Make sure you allow your eyes to fully dilate so you're able to take in as much light as possible.'

There are more things keeping sky watchers up until dawn this week than meteors and a supermoon. Checking phones or looking directly at light sources will make it harder to see streaks across the sky.

The Aurora Borealis, otherwise known as the Northern Lights, have been seen, at times, in the central and north Island region in the past few weeks. There have been reports of rare Aurora Borealis sightings in some parts of these regions.
