Airplanes very high in the sky...

Pictured above is a high-altitude jet airliner flying over Aurora and King, probably in the neighbourhood of 50,000 feet, and likely on a cross-country flight.   Grid-patterned contrails in south-central Canada are not left by U.S.A.F. B-52s.   They are condensation trails from normal daily jet aircraft operations, with grid patterns resulting from established air traffic routes in the National Airspace System (NAS).   U.S.A.F. B-52s do fly similar routes on occasion during special training and operational exercises.

Contrails form when water vapor from jet engine exhaust freezes into ice crystals in cold, humid high-altitude air.   They can appear as grids due to air traffic corridors, similar to highways in the sky, and their persistence is a result of atmospheric humidity. 

I took the photo above with my Nikon camera, using a Nikkor 55-300 mm telephoto lens and enlarged it considerably on my desk-top computer.

Hornets and wasps...

Photo by Barry Wallace

Wasps in the above photo appear to be hornets

Hornets are the largest type of social wasps, meaning all hornets are wasps, but not all wasps are hornets.   Key differences include size (hornets are larger and rounder), body features (hornets have little hair), while some other wasps have pinched waists), colour patterns (hornets often have white/yellow and black, while other wasps have more varied black and yellow patterns).

Milkweed seeds arrive...

 

Photo by Barry Wallace

Milkweed seeds "break open" (or more accurately, pods split open) in late summer to early fall, typically September to October, when pods dry out and turn brown.   Pods are ready when the centre cracks open.   At this stage, mature seeds, will be chestnut brown.

Camera on King & Aurora blog at 3,724 issues...

(taken in the rear-view mirror on the side of my car)

I write two blogs every day of the week during the year.   One is the one seen here: Camera on King & Aurora, and the other is Barry the Birder.   Last week, in my Barry the Birder blog, I wrote that I had written almost 4,600 Barry the Birder blogs over the past 18 years.

It made me wonder this week about how many Camera on King & Aurora blogs I had written, since I started in 2011.   It turns out that I have written and published photos in 3,724 entries on this blogsite.

As I mentioned in my Barry the Birder blog last week, I am going to continue blogging into future for an undetermined period of time, and that will include entries on the site you are currently perusing.   Thanks for looking up this blog from time to time and hope you continue to do so for some time to come.

Best wishes and please comment if you wish.
