The first total lunar eclipse of 2021 occurs early next week and features the largest Full Moon of the year.
Ready for the lunar eclipse drought to come to an end? It’s been a while since we’ve watched the Moon pass through the Earth’s dark inner shadow, to be sure. 2020 featured four lunar eclipses… all of which were faint penumbrals. In fact, you have to go all the waaaaay back to January 21st, 2019 (remember 2019?) to remember the last total lunar eclipse. But that wait ends next Wednesday morning on May 26th, with a very short total lunar eclipse, centered on the Pacific region.
A penumbral lunar eclipse in the early morning hours of November 30th marks the start of the last eclipse season for 2020.
Howling at the Moon Sunday night? Sunday night into Monday morning November 30th features not only the penultimate Full Moon for 2020, but the final lunar eclipse of the year, with a penumbral eclipse of the Moon.
Eclipse season resumes on June 5th, with a fine penumbral lunar eclipse.
Are you cursing the June Full Moon as it thwarts your dreams of deep-sky imaging this week? Fear not; said Moon is actually the first astronomical draw for June 2020, as this coming weekend’s Full Moon marks the start of second eclipse season for 2020, with a penumbral lunar eclipse.
There are several ways to look for alien life on distant worlds. One is to listen for radio signals these aliens might send, such as SETI and others are doing, but another is to study the atmospheres of exoplanets to find bio-signatures of life. But what might these signatures be? And what would they appear to our telescopes?
By now, you’ve heard the news. One of the top astronomy events for 2019 is coming right up on the night of January 20th into the morning of the 21st with a total eclipse of the Moon. There’s lots of hype circulating around this one, as it assumes the meme of the “SuperBloodWolf Moon eclipse” ’round ye ole web.
On Wednesday, January 31st (i.e. today!), a spectacular celestial event occurred. For those who live in the western part of North America, Alaska, and the Hawaiian islands, it was visible in the wee hours of the morning – and some people were disciplined enough to roll out of bed to see it! This was none other than the highly-anticipated “Super Blue Moon“, a rare type of full moon that on this occasion was special for a number of reasons.
For one, it was the third in a series of “supermoons”, where a Full Moon coincides with the Moon being closer in its orbit to Earth (aka. perigee) and thus appears larger. It was also the second full moon of the month, which is otherwise known as a “Blue Moon“. Lastly, for those in right locations, the Moon also passed through the Earth’s shadow, giving it a reddish tint (known as a “Red Moon” or “Blood Moon”).
In short, you could say that what was occurred this morning was a “super blue blood moon.” And as you can see, some truly awesome pictures were taken of this celestial event from all over the world. Here is a collection of pictures that a number of skilled photographers and star gazers have chosen to share with us. Enjoy!

Just to get you in the mood for the upcoming total solar eclipse — now less than two weeks away — our Solar System put on a little eclipse display of the lunar kind on August 7. The full Moon passed through part of the Earth’s umbral shadow, and the timing made this partial lunar eclipse visible in parts of Europe and Africa.

In the southern hemisphere this weekend in the ‘Land of Oz?’ Are you missing out on the passage of Comet 45/P Honda-Mrkos-Pajdušáková, and the penumbral lunar eclipse? Fear not, there’s an astronomical event designed just for you, as the Moon occults (passes in front of) the bright star Regulus on the evening of Saturday, January 11th.
The entire event is custom made for the continent of Australia and New Zealand, occurring under dark skies. Now for the bad news: the waning gibbous Moon will be less than 14 hours past Full during the event, meaning that the ingress (disappearance) of Regulus will occur along its bright leading limb and egress (reappearance) will occur on the dark limb. We prefer occultations during waxing phase, as the star winks out on the dark limb and seems to slowly fade back in on the bright limb.
The International Occultation Timing Association has a complete list of precise ingress/egress times for cities located across the continent. An especially interesting region to catch the event lies along the northern graze line across the sparsely populated Cape York peninsula, just north of Cairns.
The Moon occults Aldebaran and then Regulus six days later during every lunation in 2017. This is occultation number three in a cycle of 19 running from December 18, 2016 to April 24, 2018. The Moon occults Regulus 214 times in the 21st century, and Regulus is currently the closest bright star to the ecliptic plane, just 27′ away.
We’ve also got a very special event just under 14 hours prior, as a penumbral lunar eclipse occurs, visible on all continents… except Australia. Mid-eclipse occurs at 00:45 Universal Time (UT, Saturday morning on February 11th), or 7:45 PM Eastern Standard Time (EST) on the evening of Friday, February 10th, when observers may note a dusky shading on the northern limb of the Moon as the Moon just misses passing through the dark edge of the Earth’s inner umbral shadow. Regulus will sit less than seven degrees off of the lunar limb at mid-eclipse Friday night.
How often does an eclipsed Moon occult a bright star? Well, stick around until over four centuries from now on February 22nd, 2445, and observers based around the Indian Ocean region can watch just such an event, as the eclipsed Moon also occults Regulus. Let’s see, I should have my consciousness downloaded into my second android body by then…
This eclipse also marks the start of eclipse season one of two, which climaxes with an annular eclipse crossing southern Africa and South America on February 26th. The second and final eclipse season of 2017 starts with a partial lunar eclipse on August 7th, which sets us up for the Great American Eclipse crossing the United States from coast to coast on August 21st, 2017.
A lunar occultation of Regulus also provides a shot at a unique scientific opportunity. Spectroscopic measurements suggest that the primary main sequence star possesses a small white dwarf companion, a partner which has never been directly observed. This unseen white dwarf may – depending on the unknown orientation of its orbit – make a brief appearance during ingress or egress for a fleeting split second, when the dark limb of the Moon has covered dazzling Regulus. High speed video might just nab a double step occlusion, as the white dwarf companion is probably about 10,000 times fainter than Regulus at magnitude +11 at the very brightest. Regulus is located 79 light years distant.
Our best results for capturing an occultation of a star or planet by the Moon have always been with a video camera aimed straight through our 8” Schmidt-Cassegrain telescope. The trick is always to keep the star visible in the frame near the brilliant Full Moon. Cropping the Moon out of the field as much as possible can help somewhat. Set up early, to work the bugs out of focusing, alignment, etc. We also run WWV radio in the background for an audible time hack on the video.
The best occultation of Regulus by the Moon for North America in 2017 occurs on October 15th, when the Moon is at waning crescent phase. Unfortunately, the occultation of Regulus by asteroid 163 Erigone back in 2014 was clouded out, though the planet Venus occults the star on October 1st, 2044. Let’s see, by then I’ll be…
Comets and eclipses and occultations, oh my. It’s a busy weekend for observational astronomy, for sure. Consider it an early Valentine’s Day weekend gift from the Universe.
