North America (and western South America) have ringside seats for a total lunar eclipse overnight on March 13-14. Totality lasts from 0626 to 0732 UTC, which is 0126-0232 am daylight time March 14 in my time zone (US Central).

S&T has an excellent article including time conversions for the relevant time zones, a diagram of where the eclipse is visible, what to look for, and so on. Check it out:

Clear skies!

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.

The moon is currently completely eclipsed. My family all saw it, and now I'm crashing for the night. Sleepy

I am watching the eclipse, and the moon looks more gray than on previous eclipses. There is some red in it too. It may be because of some haze in the atmosphere that it looks gray.

Glad you got to see it, @narnian78 and @fantasia. Now, sleep well! (If our kids were still growing up here at home, I'd be crashing too. Giggle )

How is the viewing in your area, @stargazer?

I was asleep by 9:15 EDT last evening, which enabled me to wake up with greater ease just before 2:30 am. It is very pleasant outside now (clear, no wind, and -3°C / 26.6F), so we are able to stay out for a good long time without getting chilled. Everything is so hushed and still. Oddly, one peeping bird just flew overhead at 3 in the morning. Confused

In the middle of totality now at 3 am. Beautiful, ruddy, although there is a persistent thin, very light red—almost white—streak around the upper part of the Moon. I hope to be awake for quite awhile yet for viewing. Smile Using binoculars is even more stunning!

EDIT 1: The Big Dipper is high overhead, leading to Arcturus, then Spica. Always a lovely sight.

EDIT 2: And I just now (3:28 EDT) see the head of Scorpius, including Antares, rising above the trees in the SE. Very cool!

EDIT 3: About a half hour ago, at 3:40, I began to see the glimmer of the brilliant white of the Moon (upper left), as the eclipse passed totality. Checking periodically to see its progress. I even got some half-decent photos, both of totality and following. Smile  

While totality is amazing, I think the part I enjoy the most is just past totality, when that shining white rim begins to appear, with the rest of the Moon still deep in dark red.

EDIT 4: With the unaided eye, the Moon right now appears as a full crescent, but with binoculars, it is wonderfully striking, as the eclipsed part looks far more as it is ... a massive shadow slipping off the Moon.

EDIT 5: the Moon shadows are now becoming very distinct again, at 4:25 am, as the eclipse slowly passes, and the emerging full Worm Moon feels almost too bright to look at directly.

EDIT 6: I think I'm going to crash too. Took one final glimpse. The Moon is 3/4 bright again at 4:35 am. The diminishing shadow looks like a neat bite off a cookie. I don't think I will be arising for my walk in 90 minutes. Bats eyes But you never know. It's great walking weather out there! Crisp, comfortably cold.

Wonderful viewing tonight! ♥ Over and over "The heavens declare the glory of God"!

I'm glad you all got to enjoy the eclipse!

Skies here ranged from slightly hazy with a few clouds at the beginning of the umbral phase (12:09 am our time), to hazier skies by mid-eclipse (1:59 am), to hazy skies with scattered clouds by the end of the eclipse (3:48 am).

The temperature as we began was a very comfortable 55F/13C, well above our average high. The timing was also good as a big storm will roll in less than 24 hours after this event.

In warm weather I'll often sit outside for most or all of the event (as with last September's partial event, or the total one in May 2022 which I enjoyed with friends). This time, I ventured outside for some of the main events but spent the rest of the time indoors. It was still comfortable enough to sit in a lawn chair and take in the view.

Ryadian's father observed with me, until he called it a night around the beginning of totality. He noted that the haze made the penumbral shading easier to see by reducing the usual glare of the full moon.

We were outside for the beginning of the umbral phase, as well as seeing the moon about 40% covered (around 12:50). By then the eclipsed part was definitely visible, especially in binoculars. We saw 7 or 8 deer go walking down the street (oddly, this also happened during the last eclipse too). Deer are common enough around here but I usually don't see them while stargazing.

By the time totality started (1:26 am), the covered part was dark near the bottom, red and orange in the middle, merging to a brighter spot near the top of the Moon. I was reminded of pictures of Mars and its polar ice cap. By now, the surroundings were noticeably darker, even with all the city lights.

I watched mid-totality, and it seemed the brighter edge was slowly moving counterclockwise around the top of the moon as time passed. The man-in-the-moon figure was clearly visible in binoculars, especially as the end of totality neared. The sky was fairly hazy by now, with first-magnitude Spica barely visible (it's usually easy to see despite city lights). Another lone deer was seen in the street around the time totality ended.

As the end of the eclipse neared, moon shadows appeared on the ground again, and the sky was now pretty hazy and about half-filled with scattered cumulus clouds.

I agree!

The news says that there will be a partial solar eclipse tomorrow, visible in Norway (as about 30%) at about lunchtime. In North-Eastern America you should be able to see it in the early morning. All depending on the clouds, of course.

If I'm able to see it at all, I need to be very careful, as I have no equipment for protecting my eyes. I guess I ought to treat it as I would do with the sun on an ordinary occasion - look at the sky and only have the sun in the side view, not looking directly at the sun itself (other than perhaps a second's glance or two at it - that would be two glances, not two seconds).

If the clouds are making it unnoticable, I should find it online instead, from somewhere with clear skies ...

Edit 1:

Most of the eclipse was visible in most of Norway (some areas were too cloudy). I had a couple of glimpses of the sun itself, but only for fractions of a second, which was not long enough to see that something was blocking out a section of the sun's surface.

I did what I had expected all along to have to do - I went inside and watched it online. A Norwegian sun observatory had a video camera running all along, for nearly two hours. Which makes it too slow to observe the actual movement. You just notice occasionally that the shadow has moved.

I only watched the second half of it, and not solid. I started at about maximum (should have started much earlier), and watched occasionally for a few minutes at a time until it was over. I did enjoy it, though. The next eclipse that can be seen in Norway, is in August next year. I've put it in my calendar.

Edit 2:

Later in the day I found an international site with a video (of nearly 3 hours) of the whole event:

Next time I want to watch such astronomical events, I should try timeanddate.com first. Giggle

I'm glad you got to see something of the eclipse, Varna! (I'm too far west to have had a chance at it).

timeanddate is one of my go-to websites for a variety of astronomical things; other sources are spaceweather.com and the "This Week's Sky at a Glance" section on skyandtelescope.org.

Venus has already emerged into the morning sky after passing between the earth and sun last week, but I haven't seen it yet (due to a combination of clouds and poor horizon viewing in that direction). Over the next few weeks Saturn and Mercury will join it, leaving just Mars and Jupiter in the evening sky.

There have also been a lot of Northern Lights reports the past few weeks, and there is an active sunspot region coming into view that may send some more our way (spaceweather is one of the best sources for solar flare and aurora information). We saw a very modest display on March 27, but the weather has not been cooperating otherwise.

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.

I thoroughly enjoyed reading your experience of the lunar eclipse, @stargazer, and yours with the partial solar eclipse, @Varna! Smile  

A couple of mornings ago the night sky was brightly shining on my walk! All winter long I have been watching Venus move across the sky, and set in the west at night, only to emerge now rising in the eastern sky. This was my first sighting of it in 2025 in the morning hours. There were large dark strips of cloud to the east, but thankfully a strip of clear between them, which is where bright Venus was. A beautiful view in every way!

I could not spot the great square of Pegasus, even though it is left by Venus, as dawn was brightening too much (6:30 or so, a half hour before sunrise).

Mercury and Saturn are below Venus, very close to the horizon, and basically impossible to see in the growing dawn.

The temperature that morning was -4C / 24.8F, with a few degrees windchill, bringing it down to around -10C / 14F. Great for walking! High overhead was Cygnus; in the south Scorpius was rising higher, and Antares easily stood out. What an interesting constellation it is; it seems to go on and on.

The Big Dipper in the north, as always, pointed its way to Arcturus, then to Spica, always fun to see.

I am having to walk gradually earlier and earlier as the sun's rising time changes, if I want to walk under the night sky. Which I do! Smile Star

@jo, your post inspired me to get outside this morning and look for Venus. I stumbled out the door around 6am local daylight time to find significant twilight (nautical twilight began at 5.38 and civil at 6.14).  Few stars were visible, notably Arcturus in the southwest.

I walked down to the corner for a better view to the east, and spotted Venus about 5 degrees high in the E, shining through the still bare trees. I enjoyed seeing it again and noted that in a few weeks it would be harder to see it so low in the sky since the trees are about to burst into leaf. 

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.
