The light of the full moon will cover one of the biggest “stars” of the year

In August, we will really feel the days getting shorter. On the 1st, the solar set round 20:45 in Portugal, however on the thirty first, it set round 20:00.

This additionally impacts the look of the planets. On the 1st, the planet Saturn was born shortly after darkish, round 9:30 pm, however at the finish of the month, it’s already seen when the Sun passes beneath the horizon. But in August, we will have the probability to see all 5 seen planets.

Mercury has simply left the Sun and is starting to see itself in the night. The finest time to see it will be between 13 and 19. Even so, this planet will be 10 levels above the horizon (with an outstretched arm, it corresponds kind of to the house with a closed fist) and it may be seen between half an hour and 45 minutes. To enhance the possibilities of seeing Mercury, it is suggested to take action in an unobstructed west-facing place.

Jupiter and Mars will not be seen in the night, however as the moon progresses, they will rise early and early. The largest planet in the Solar System is born at 11:15 pm on the 1st, however will seem at 9:15 pm on the thirty first. , and midnight on the evening of the thirty first.

As for Venus, it’s already approaching the Sun – it was born round 05:00 on the 1st, and 06:00 on the thirty first.

The moon, which strikes a bit of greater than a hand a day in the sky, was in the crescent on the fifth. Per week later, on the twelfth, it reaches the part of the full moon and passes solely 5 levels from Saturn.

Unfortunately, that is additionally the day when the Perseid storm, one of the “huge stars” of the year, reaches its peak. So though this bathe has as much as 100 meteors seen per hour (in a darkish sky), the moonlight ought to lower that quantity in half.

In cities, as a consequence of the loss of light, the quantity of meteors seen is about 10% of the quantity anticipated in the darkish sky, that’s, solely 5 ought to be seen per hour. But it isn’t all dangerous information, as the Perseids are wealthy in “balls of hearth” (massive and vibrant meteors), so they need to spend an hour the sky.

On the 14th, Saturn will come to opposition, that means that the Sun, Earth and Saturn will be in concord, with Saturn on the reverse facet of the sky from the Sun.

On August 15, the starting of the vacation for some and the finish for others, Mercury will be at its highest level, in the night, and some hours later, the Moon passes via 6 levels of Jupiter. On the nineteenth, the day the Moon reaches its minimal, it passes three levels of Mars.

So now we have to attend till the twenty fifth, when our satellite tv for pc, very barely, passes at 7 levels of Venus, simply earlier than daybreak. On the twenty seventh is the day of the new moon and on the twenty ninth now we have the drawback of seeing the moon: the thinnest moon will be at 4 levels of Mercury, however the earth is already approaching the Sun, in the sky, and ought to be seen for lower than half an hour, simply after sundown.

Great evaluations!
