Total Solar Eclipses and the Great American Eclipse on April 8, 2024
A total solar eclipse is one of the most amazing visual and sensory experiences you can find in nature, a combination of astronomical alignments and local phenomena that combine to dazzle us humans when we witness this spectacle. I caught the 'solar eclipse bug' decades ago and have traveled far and wide over the past years to be in the shadow of the moon many times. I find it to be a profoundly moving experience, and I am heading to the next one in April 2024 that will be visible across a large swath of North America. During a total solar eclipse, there are three broad categories of the experience.

Lunar X and V on October 21st
The Moon is a fantastic target for anyone with a telescope or binoculars. There is so much richness to see and on any night the Moon presents an ever-changing landscape, each night different from the previous one. I particularly like first and last quarter moons, as you get a side view of the terminator and can observe the long shadows in the craters. But those shadows and the rapidly changing lighting effects on and near the terminator create striking patterns for those with a good telescope.
Lunar X and V |
This month the view is favourable where I live, here in Munich, Germany. On Saturday October 21st the X and V features will be visible just at sunset and for an hour or two afterwards. I will host a star party in the Englischer Garten in Munich for the public and I hope that many will join to see this unique spectacle.

Total Solar Eclipse in Australia: watch live
Happy viewing. I'll post comments later.

Here is my report from later on 20 April: it was an impressive eclipse, with a very sharply defined corona. The prominences were like I have never seen before, with one very extended prominence and one beautifully curved prominence that had a broken filament. The sky was crystal clear and the spectators at my site here in Exmouth were quite excited by the whole thing.
I have added two photos from the photographers next to me. The one above shows the Diamond Ring effect, and the one below totality with the solar corona.

Total Lunar Eclipse: 15-16 May 2022
A total lunar eclipse takes place on the evening of May 15th, continuing into the early morning of May 16th. It favors the Western Hemisphere, with best viewing conditions in the evening and late night of Sunday May 15th. For those on the West Coast of the US, the Moon will rise in deep partial eclipse and reach total phase at 8:29 pm pacific time, just after sunset in Los Angeles. Further east, the full eclipse will be visible in darkness. In eastern time zone, the partial eclipse starts at 10:28 pm and reaches totality at 11:29 pm. Totality lasts 1 hour and 25 minutes. Unfortunately for those in Europe, the eclipse will start in the early morning hours (4:28 in Germany) and will reach totality just as the Sun is about to rise, so it will be interesting but not nearly as impressive as when seen in darkness.
No special viewing locations are needed, just a clear view to the south (and for the west coast of the US, a clear view to the east), and good weather. There are many factors that can affect the appearance of the eclipsed moon at totality ... largely due to weather conditions on Earth. And the 85 minutes of totality also can change in appearance from the start to the middle to the final moments before direct sunlight returns to the lunar surface.Sky and Telescope has an excellent write up for this event, with great details about many aspects of lunar eclipses.
I wish you clear skies and a fun time viewing this special moment.

Perseid Meteor Shower 2021
The Perseid radiant |
The Perseids are upon us, literally. As the Earth sweeps around the Sun in its orbit, we gently glide through a region of space dust and debris, the remnants of a comet that passes through Earth's orbit every 133 years or so. And lucky for us, all of this debris is far too small to cause any damage to us on Earth, but big enough to light up the night sky every year.
The Perseid Meteor shower in 2021 takes place over a two-day window on 11-12 August (through the morning of August 13th). The peak is expected to be late on the night of August 11th-12th. At the peak with very clear skies and dark conditions, you could see up to a meteor per minute. But that is an average, and sometimes you can have many minutes go by without any meteors, and then suddenly 2 or 3 all at once. So the best way to see the Perseids is to be patient, find a location with a broad horizon, and my favorite thing -- to do this in a group (even a group of two will do) since more eyes will see more meteors. I enjoy setting up the group to be looking in all different directions so we don't miss any meteors and even though no one person will see 100% of the meteors, we can all enjoy the excitement and fun with friends. Having a comfortable lounge chair and a blanket are a bonus and will enhance your viewing.
As with every meteor shower, the viewing gets better after midnight when more meteors are flying into the atmosphere, so get lots of rest the night before and be ready for a long, relaxing night viewing one of the best meteor showers of the year.
Lucky for us, we have a dark night for viewing the meteors, as the Moon is just a few days past New Moon phase and will set early in the evening. No light from the Moon makes the whole experience better.
This article from Sky and Telescope is an excellent overview of the Perseids, not only tips how to best observe the shower, but why it happens every year and other interesting science.
