February has been an impressive month for astronomical observation. Last month ended on a high note after having one of the most anticipated astronomical events in years: the alignment of 7 planets in the sky. The astronomical calendar for March does not disappoint. During the first week, many planets are still visible in the sky, mainly Venus, Mars, Jupiter and Uranus. In the case of Mercury, it will be the best time to observe it and the most notable thing is the partial solar eclipse visible in Spain and Portugal.

The Moon and Jupiter put on a show in Taurus
On March 5th, the crescent Moon will pass 5º from Jupiter. From Barcelona, you have to look west to observe it from 9:51 p.m. on March 5th. Our natural satellite will be located in the constellation of Taurus, just above the Pleiades star cluster and the planet Uranus. It is a good opportunity to see a great show in the sky, especially if you have a telescope. Ask us for advice if you would like to buy a telescope,click here to send us a whatsapp.
Maximum elongation of Mercury
It is the best time to observe the planet Mercury, which is reaching its maximum elongation. The phenomenon occurs when Mercury is at its maximum apparent distance from the Sun, and becomes visible in the sky after sunset.
Reaching magnitude -0.3 on March 7, Mercury will appear as a bright point of light on the horizon just after sunset. The best time to observe it is around 7:56 p.m. Be careful of sunlight if you want to use a telescope; wait until full sunset to avoid risks.
Conjunction of the Moon and Mars
The Moon and Mars will form a beautiful conjunction in the sky during the night of March 8. Only 1º will separate both objects in the sky and it will be an excellent time to practice your astronomical observation of the Moon and Mars. Get your telescope ready, because at 8:55 p.m. on March 8 the show begins over the constellation Gemini.
Partial solar eclipse
A partial solar eclipse will occur on March 29 at 11:48 a.m. (Spanish peninsular time). From Barcelona, the Moon will partially cover the Sun from 11:01 a.m. to 12:36 p.m., and the maximum will occur at 11:48 a.m.
Partial solar eclipses occur when the Sun, Moon and Earth are not exactly aligned.
