Chasing the Shadowed Moon (2022)

Once again, catching the eclipsed Moon required a chase to clear skies.

As with every previous eclipse of the Moon visible from my area in the last decade, I didn’t have the luxury of watching it from home, but had to chase to find clear skies.

(See my previous tales of the November 19, 2021 and May 26, 2021 eclipses.)

However, the reward was the sight of the reddened Moon from one of my favourite locations in Alberta, Reesor Lake, in Cypress Hills Interprovincial Park.

The eclipse in question was the total lunar eclipse of May 15/16, 2022. As with any eclipse, planning starts with a look at the weather forecasts, or more specifically cloud forecasts.

A few days prior, conditions didn’t look good from my home, to the west of the red marker.

But as the chart from the app Astrospheric shows, very clear skies were forecast for southeast Alberta, in the Cypress Hills area, where I have shot many times before.

Except as eclipse evening drew closer, the forecast got worse. Now, the clouds were going to extend to my chosen site, with a particularly annoying tongue of cloud right over my spot. Clouds were going to move in just as the total eclipse began. Of course!

I decided to go for it anyway, as the Moon would be to the east, in the direction of the clear skies. It didn’t need to be clear overhead. Nor did I want to drive any farther than I really needed, especially to another location with an unknown foreground.

The spot I chose was one I knew well, on the west shore of scenic Reesor Lake, near the Alberta/Saskatchewan border, but on the Alberta side of Cypress Hills Interprovincial Park.

I used the app The Photographer’s Ephemeris (TPE) to help plan the shoot, to ensure the Moon would be well situated over the lake.

Handily, TPE provides moonrise times and angles for the chosen location, as well as eclipse times for that time zone.

The companion app, TPE 3D, provides a preview of the scene in 3D relief, with the hills depicted, as a check on Moon altitude and azimuth with respect to the horizon below.

As you can see the simulation matched reality quite well, though the image below was from an earlier time than the simulation, which was for well after mid-totality.

However, true to the predictions, clouds were moving in from the west all during the eclipse, to eventually obscure the Moon just as it entered totality and became very dim. Between the clouds and the dark, red Moon, I lost sight of it at totality. As expected!

Below is my last sighting, just before totality began.

However, I was content at having captured the eclipse from a photogenic site. More images of a complete eclipse would have been nice, but alas! I still consider the chase a success.

Just for fun, I shot a quick panorama of three segments, and it turned out to be my favourite image from the eclipse, capturing the scene very well. Pelicans and geese were plying the calm waters of the lake. And owls were hooting in the woods. It was a fabulous evening!

Before departing, I took my customary “trophy” shot, of the eclipse hunter having bagged his game.

Interestingly, this eclipse was a close repeat of one 19 years earlier to the day, because of the so-called Metonic Cycle where eclipses of the Sun and Moon repeat at 19-year intervals on the same calendar day, at least for 2 or 3 cycles.

On May 15, 2003, we also had a total lunar eclipse in the early evening, with the eclipsed Moon rising into a spring twilight sky. I also chased clear skies for that one, but in the opposite direction from home, to the southwest, to the foothills. At that time it was all film, and medium format at that.

So it was another (partially!) successful eclipse chase.

The next opportunity is on the night of November 7/8, 2022, a time of year not known for clear skies!

Just once I would like to see one from home, to make it easier to shoot with various telescopes and trackers, as the reddened Moon will be west of the photogenic winter Milky Way, and very close to the planet Uranus. Plus for me in Alberta the November eclipse occurs in the middle of the night, making a home eclipse much more convenient. After that, the next chance is March 13/14, 2025.

But no matter the eclipse, I suspect another chase will be in order! It just wouldn’t be a lunar eclipse without one.
