So, there are interesting things going on in the night sky right now. Betelgeuse, the shoulder of Orion the Hunter, is the dimmest it has been. This is exciting for astronomers because it could be the prelude to Betelgeuse going supernova. Or not. (Or at least not yet.) It is, apparently, visibly dimmer than it was just a few weeks ago, which is a pretty big deal, astronomically-speaking.

Merry Christmas, everyone! The Christmas season can be stressful for some people, so I hope everyone has a safe, happy and relaxing Christmas season with friends and family!

We pause today to remember all those who have made the supreme sacrifice in order that we may have peace and freedom.

Thank you seems so inadequate.

While starting to prepare for observing the transit of Mercury on Monday, I took a look at the cloud cover forecast for Monday morning. It’s not terribly encouraging:

There is an intriguing hole in the Eastern Townships near Sherbrooke. That might be the place to be.

Maybe the forecast will change between now and then. (It could happen.)

The planet Mercury will passing across the face of the sun on Monday, November 11th. The transit starts at 07:35am Eastern (12:35 UTC) and ends at 1:04pm (18:04 UTC). This will be the last transit of Mercury until November 13th, 2032 (it’s a Saturday).

Observing it is a bit challenging because you can’t just walk outside with a pair of binoculars and stare at the sun to see the tiny black dot that will be Mercury. You need special solar filters for your binoculars/telescope/camera to make it safe to look at — a neutral density filter is not sufficient. If you don’t use an appropriate solar filter, you risk causing yourself serious eye damage and you could also ruin your binoculars/telescope/camera in the process.

I observed the last transit of Mercury in May 2016 in front of where I work at lunch using a piece of #14 welder’s glass in front of the lens of my camera. My plans for the upcoming transit include both my 6″ telescope and my William Optics RedCat 51, with proper solar filters, of course!

If you’re like most people, you probably don’t have the necessary equipment. If you want to observe it, members of the Ottawa Centre of the Royal Astronomical Society of Canada will be at Marion Dewar Plaza outside Ottawa City Hall (110 Laurier Avenue West) from 7:30am to 1:30pm with their telescopes and the public is welcome to drop by and observe it safely. Monday is Remembrance Day, so be sure to leave yourself lots of time to get there.

So, in just over two hours much of Canada starts turning the clocks back an hour because Daylight Saving Time is ending. This means that we’ll have more darkness at the end of the day, see an increase in the injuries and deaths in the next week or so, and we won’t save any more energy or money in the process.

It’s high time that we end the madness and stop changing the clocks. Let’s change to Daylight Saving Time one more time in the spring and then stop messing with the clocks forever. Saskatchewan doesn’t change their clocks and they seem ok. British Columbia, for example, is talking about doing it and I’m confident they’ll be ok. Let’s make the decision as a country to leave the clocks alone. Please.
