What to Know About Wednesday’s ‘Super Blue Moon’

The second supermoon of the month will rise this Wednesday, August 30. It will be even closer to Earth than the first supermoon of the month, the so-called Sturgeon Moon that rose on August 1. Moon Knight Gives Us Hope Supermoons describe full Moons that occur within 90% of the Moon’s perigee, or its closest approach to Earth in its orbit. To the naked eye, supermoons make our lunar satellite…

The celestial object of the day is Spica!

The brightest star in the constellation of Virgo is actually a binary system! And the closest to the sun. It's formed by a blue giant and a variable star, they orbit so close together that they've gained an ellipsodal shape, similar to that of an egg

Solar Eclipse Image Credit & Copyright: Fred Espenak

Explanation: On April 20, 2023 the shadow of a New Moon raced across planet Earth's southern hemisphere. When viewed along a narrow path that mostly avoided landfall, the Moon in silhouette created a hybrid solar eclipse. Hybrid eclipses are rare and can be seen as a total eclipse or an annular "ring of fire" eclipse depending on the observer's position. Viewers of this much anticipated hybrid event were able to witness a total solar eclipse while anchored in the Indian Ocean near the centerline of the eclipse track off the coast of western Australia. This ship-borne image from renowned eclipse chaser Fred Espenak captured the active Sun's magnificent outer atmosphere, or solar corona, streaming into space. The composite of 11 exposures ranging from 1/2000 to 1/2 second, taken during the 62 seconds of totality, records an extended range of brightness to follow alluring details of the corona not quite visible to the eye.

Hybrid Solar Eclipse

Credit & Copyright: Left: Fred Espenak - Right: Stephan Heinsius

Explanation: April's spectacular geocentric celestial event was a rare hybrid eclipse of the Sun - a total or an annular eclipse could be seen depending on the observer's location. For Fred Espenak, aboard a gently swaying ship within the middle of the Moon's shadow track about 2,200 kilometers west of the Galapagos, the eclipse was total, the lunar silhouette exactly covering the bright solar disk for a few brief moments. His camera captured a picture of totality revealing the extensive solar corona and prominences rising above the Sun's edge. But for Stephan Heinsius, near the end of the shadow track at Penonome Airfield, Panama, the Moon's apparent size had shrunk enough to create an annular eclipse, showing a complete annulus of the Sun's bright disk as a dramatic ring of fire. Pictures from the two locations are compared above. How rare is such a hybrid eclipse? Calculations show that during the 21st century just 3.1% (7 out of 224) of solar eclipses are hybrid while hybrids comprise about 5% of all solar eclipses over the period 2000 BC to AD 4000.

Rare 'blue supermoon' — the biggest and brightest full moon of the year — rises Aug. 30 | Live Science

The biggest and brightest full moon of 2023 will rise on Aug. 30, and its strange name deserves an explanation. Called a "blue supermoon," it is the result of three lunar phenomena happening at once.

The "blue" supermoon's name has nothing to do with the moon's color. In fact, it will actually be orange. The blue supermoon gets the first part of its name for a different reason: It's the second full moon in August.

There are two types of blue moon. The August blue supermoon falls into the first category: two full moons occurring in the same month. That's occasionally inevitable; a new full moon rises every  29.5 days. Given that the Sturgeon Moon occurred on Aug. 1, 2023, the Aug. 30 full moon will be a blue moon. Blue moons of this type, called "calendar blue moons," occur roughly every two or three years, with the next one occurring on May 31, 2026, according to timeanddate.

The second type of blue moon, called a "seasonal blue moon," describes the third full moon of four during one astronomical season. This occurs when a calendar year has 13 full moons instead of the typical 12. (A lunar year — 12 orbits of Earth by the moon — takes 354 days, while Earth's solar year is 365 days.) The next seasonal blue moon, which also happens every two or three years, will occur on Aug. 19, 2024, according to timeanddate.

So, where does the second part of the name come from? A supermoon occurs when the full moon is close to its nearest point to Earth in its orbit. The moon's orbit of Earth is elliptical, so every month, it reaches a closest point (perigee) and farthest point (apogee). Moons that come within 90% of perigee in a given month qualify as supermoons, according to Fred Espenak, an astronomer and former eclipse calculator for NASA.

August's second full moon is the third and closest of four supermoons in 2023. At 222,043 miles (357,344 kilometers) from Earth, it will be the biggest and brightest supermoon of 2023, though it will be only 20 miles (33 kilometers) closer than Aug. 1's full moon, which was 222,023 miles (357,311 km) away.

The next full moon will be the Harvest Moon, on Sept. 29. In addition to being one of the best-known full moons of the year, it's the last supermoon in 2023.

Full supermoons in 2024

Fred Espenak’s full supermoon table gives us these values – dates and moon distances – for full supermoons in 2024. Contrast these moon distances to the average moon distance of 238,900 miles (384,472 km).

Note: Fred’s dates are based on UTC time, so some supermoons may fall on the previous date your local time.

Aug 19: 224,917 miles (361,969 kilometers)

Superluna del Cervo, è la prima del 2023: dove vederla lunedì 3 luglio. Adnkronos - ultimora

(Adnkronos) - Luna piena oggi, lunedì 3 luglio. Si tratta in realtà di una Superluna. Ma di cosa si tratta? Si parla di Superluna (o Super Luna) quando la fase di Luna piena si verifica con il nostro satellite nei pressi del perigeo, ovvero il punto della sua orbita alla minima distanza dalla Terra. Quindi il disco lunare apparirà lievemente più grande come dimensione angolare e un po’ più brillante rispetto a quanto abbiamo visto nei mesi precedenti del 2023, quando la fase di Luna piena è capitata con il satellite meno vicino alla Terra si legge su EDuINAF che dedicherà una diretta all'evento a partire dalle 21.30.   Quando la Luna si trova in fase di plenilunio in prossimità del suo passaggio al perigeo, si parla comunemente di Superluna poiché il disco lunare appare più grande, fino al 14 per cento in più, con una luminosità maggiore fino al 30 per cento rispetto alla stessa configurazione, ma all’apogeo.   Benché negli ultimi anni la Superluna sia diventata sempre più popolare a livello mediatico, non sarà possibile notarla a occhio nudo. Vanno utilizzati strumenti adeguati per constatare e misurare con precisione queste variazioni. La Luna è diventata piena intorno alle 13.38 di oggi in Italia: il nostro satellite, rispetto alla sua distanza media dalla Terra di circa 384.000 km, si troverà invece a 'soli' 361.934 km, secondo i calcoli (li trovate qui) di uno dei maggiori esperti mondiali in materia, lo studioso statunitense Fred Espenak, già ricercatore della NASA.  Il termine superluna è stato coniato da un astrologo nel 1979 e proprio per questo motivo non è ben visto dalla comunità scientifica ricorda iLMeteo.it. E perché "del cervo"? Questo nome fu assegnato dagli Algonchini, una tribù di nativi americani, poiché proprio in questo periodo dell’anno i cervi rinnovavano i palchi delle Corna. Per gli animali, questo rappresenta nuovo vigore, rinascita, la possibilità di lottare per ottenere il potere, per dimostrare la forza.  cronaca Read the full article
