Eyes to heaven for two eclipses scheduled in June. It starts on June 5 with a partial lunar eclipse of penumbra, and continue on June 21 with an annular eclipse of the Sun.. This was reported by the Italian Amateur Astronomers Union (IAU). The penumbral lunar eclipse of June 5 is the second of the year, after that of January 10, and it will be barely perceptible to the naked eye like a slight blur of a portion of the Full Moon disk.
The ring finger of the Sun of June 21, which welcomes the summer, will be clearly visible in Africa, Saudi Arabia, India, China and the Pacific Ocean, while in Italy you can see a tiny partial eclipse of the Sun in the early morning and only in the center-south. For the occasion, the UAI is organizing a Sun Day with its territorial delegations from the regions where the eclipse will be visible, to organize remote observation of the Sun and eclipse.
This year, the beginning of summer will take place slightly earlier: the solstice will in fact be at 23.44 on 20. On the longest day of the year the Sun will rise at 5.36 and set at 20.51, with a total duration of 15 hours and 15 minutes . On the other hand, among the planets, it is worth mentioning Mercury, which still remains clearly visible in the evening at the beginning of the month, in particular on June 4, while Venus it will be in conjunction with the Sun on the 3rd, returning visible on the horizon at the first light of the morning at the end of the month, when it will be the brightest star. The observability interval of the other planets generally lengthens, slowly for Mars, observable in the second part of the night, and in a more sensitive way for Jupiter and Saturn, which will be protagonists of the summer months. On the night between 8 and 9 June, around midnight, the Moon, with Jupiter and Saturn in conjunction, will be a spectacular trio of stars. Finally, in June the summer constellations return, especially the zodiacal ones from Leo to Sagittarius.
