OCTOBER 2019

October 3 / The Moon and Jupiter in conjunction

 
Sharing the same sky area in the constellation Ophiuchus, the Moon and the giant planet Jupiter will apparently be very close from our terrestrial perspective. These "planetary encounters" happen because both celestial objects are in constant motion and on some occasions they usually meet. However, it is important to clarify that even though they will look very close, in reality they are separated by millions of kilometers.


October 5 / The Moon in the First Quarter


Within a week of becoming completely full, our natural satellite will be in its First Quarter phase in the constellation Sagittarius. In this phase, the Moon is 50% illuminated. It is an ideal time to observe the lunar geography in great detail and marvel at its craters


The Moon and Saturn in conjunction


The ringed giant Saturn, still in the constellation Sagittarius, will be intimately accompanied tonight by our natural satellite, the Moon in its "First Quarter" phase. Recall that in these planetary configurations, even though the two objects appear close from our perspective, they are actually millions of kilometers apart.


October 10 / Moon at its peak


Because the orbit of the Moon around the Earth is not perfectly circular but elliptical, every certain time it reaches a point of maximum distance called apogee. In this month the lunar apogee happens on October 10.


October 13 / Full Moon


Tonight will be the scene of the 10th Full Moon of 2019 and the first of the autumn season. The belief that the October Full Moon is the most beautiful of the year is born in Europe through the arrival of harvest time. In ancient times they used to celebrate the first Full Moon after the autumnal equinox which usually happened in October. However, it is necessary to point out that our natural satellite in its full phase is different every month and every year and defining which of all is the best is a matter of perspective. The Moon will be in the constellation Pisces.


October 21 / Last Quarter Moon


One week after the Full Moon we will have our natural satellite in the Last Quarter. During this phase, 50% of the visible face of the Moon is visible from midnight (1:00 am Cozumel time). The Moon will be in the constellation Cancer.

.

October 22 / Orionids


This meteor shower occurs from October 2 to November 7, having its maximum activity at dawn on October 22, during which time 20 meteors can be seen every hour. The Orionids have their origin in the dust grains left by the famous Halley's Comet. The brightness of the waning moon will dull some meteors, but the Orionids are known to be bright so it might surprise viewers.


October 26 / Moon in perigee


Because the orbit of the Moon around the Earth is not perfectly circular but elliptical, every certain time it reaches a point of maximum approach called perigee. In this month the lunar perigee happens on October 26.


October 27 / Uranus in opposition


The planet Uranus will be at its closest approach to Earth, it will be completely illuminated by the Sun and will look brighter than any other time in 2019. However, due to the enormous distance that still prevails between both planets it will only be seen as a small greenish circle even with the most powerful telescopes.


October 28 / New Moon


When the Moon is located in conjunction with the Sun, that is, in the same area of ​​the sky next to our star king, our natural satellite is invisible to us due to the daytime glow of our star. The great advantage of this moon phase is that the night sky is the ideal one to delight us with celestial objects that are normally difficult to appreciate such as nebulae and galaxies. The Moon will be located in the constellation Virgo.
