Near Above Round Single Pulses of Amber White Light 7-8 Times Under One Minute

Last night February 25 ,while on my deck in Oshawa
I was barbecuing alone in minus below zero temperatures
While outside I was admiring the clear night sky - stars
Then get this feeling of seeing something looking
Facing north near directly above the roof
Noticed this single pulse of white amber light color
As it would pulse you could make the shape from the light as it goes out
The shape was quite round
After couple pulses pulled out my camera to capture this anomaly on film
Trying to film it noticed the pulse would occur every three - five second intervals
After about eight or nine these pulses in total
It stopped as I lowered the camera looking
No more pulses as I'm looking in that spot
The video time stamp was at 8:10 pm est
When reviewing on footage on the computer
Have captured these strange pulses of light twice
Please note I have seen these types before in previous Summers
Appears to be earlier this year for 22
Should be quite a show this Summer
