Total lunar eclipse<\/strong><\/p>\n\n\n\n

We have a total lunar eclipse this month. On the 7th<\/sup> Universal Time, Africa,Europe, Asia, Australia, and the Pacific Ocean get to see at least part of it. Parts of eastern Brazil and western Alaska do too. Everywhere else in the Americas will be on the wrong side of the earth for this event. The hard-to-see penumbral phase starts at 15:28. At 16:27, the partial phase starts. Then totality is at 17:31. Greatest eclipse is at 18:12. Totality ends at 18:53. The partial phase is over at 19:56. And the penumbral phase ends at 20:55. This will be a moonrise event for that slice of Brazil, the Atlantic, Africa, and Europe. It happens at moonset for Australia, the Pacific, and far east Asia, plus that part of Alaska.<\/p>\n\n\n\n

Partial solar eclipse<\/strong><\/p>\n\n\n\n

On the 21st<\/sup> Universal Time, the moon passes in front of the sun. The moon’s umbral shadow cone passes too far south of Earth for a total phase. Observers in New Zealand, Fiji, and Vanuatu get a sunrise event. Other parts of the southern Pacific get a complete event from partial phase beginning to ending. Greatest eclipse is of magnitude 0.855 close to eastern Antarctica. Remember to protect your eyes with safe solar viewing filters or a safe projection method to see this eclipse.<\/p>\n\n\n\n

Other events<\/strong><\/p>\n\n\n\n

Right after sunset, Mars is marching on a path that will go by Spica in Virgo as the middle of the month approaches. It will be a little hard to see from the northern hemisphere as the planet and constellation sink lower into the sunset. You need a clear horizon to the west. The view is easier from the southern hemisphere where you also get Mercury very close to the horizon at dusk in the last few days of the month. The moon passes near Spica on the 24th<\/sup> and Mars the next evening.<\/p>\n\n\n\n

Don’t confuse orange Arcturus for Mars in the evening sky. The bright star at the bottom of Bo\u00f6tes is higher up than Mars at dusk.<\/p>\n\n\n\n

Most observers will see Saturn rising at dusk. The ringed planet will be at opposition on the 21st<\/sup>, 8.55 astronomical units from us. Neptune is nearby and is at opposition on the 23rd<\/sup>. Its distance is 28.9 a.u.!<\/p>\n\n\n\n

Uranus rises in late evening. It’s still hanging out between the Pleiades and the Hyades.<\/p>\n\n\n\n

Early morning riser Jupiter starts the month near Wasat in Gemini. The big planet will appear closest to the star on the 6th<\/sup> and 7th<\/sup>. The moon passes by on the 16th<\/sup>. At month’s end, Jupiter hasn’t gotten much farther along and is on still on the east side of Gemini.<\/p>\n\n\n\n

\"Jupiter,<\/figure>\n\n\n\n

Closer to dawn, Venus rises, starting September near Asellus Australis in Cancer. Venus marches on into Leo and is closest to Regulus on the 19th<\/sup> and 20th<\/sup>. The moon passes by them at the same time. The planet has made it most of the way toward the lion’s back feet as September ends.<\/p>\n\n\n\n

Some observers can find Mercury approaching Regulus early in the month. The messenger planet passes the star on the 2nd<\/sup>. Low northern latitudes get the best view, but even from there the pair are very close to the horizon with the sunrise glow getting bright. Mercury’s headed to superior conjunction on the 13th<\/sup>. After that, you can look for Mercury to reappear in the evening if you’re at a low southern latitude. A young moon will be close on the 22nd<\/sup>, but that won’t really help. Both will be lost in the sunset glow.<\/p>\n\n\n\n

The moon<\/strong><\/p>\n\n\n\n

On its way around the celestial sphere this month, the moon begins at southern lunistice on the 1st<\/sup> at 28.6\u00b0 south of the equator. It’s just after first quarter phase that day. Of course, it’s full on the 7th<\/sup>, the date of the aforementioned total lunar eclipse. On the 8th<\/sup>, Luna crosses the equator going north. It’s 3.5\u00b0 from Saturn and 2.5\u00b0 from Neptune the same night. Lunar perigee is on the 10th<\/sup> at 364,700 km away. The moon passes 5.2\u00b0 from Uranus on the 12th<\/sup>. Northern lunistice is on the 14th<\/sup>. The moon will be 28.6\u00b0 from the equator. On the 16th<\/sup>, Luna passes 4.5\u00b0from Jupiter and 2.4\u00b0 from Pollux. The Venus-moon pairing for the month is on the 19th<\/sup> at 0.7\u00b0 separation. The moon will also pass 1.2\u00b0 from Regulus that day and Venus will be 0.5\u00b0 from the star. It’s across the equator going south on the 21st<\/sup>, the same day as new moon and the solar eclipse. Then the moon’s 2.5\u00b0 from Mercury on the 22nd<\/sup>, 1.0\u00b0 from Spica on the 23rd<\/sup>, and 3.6\u00b0 from Mars on the 24th<\/sup>. Apogee is on the 26th<\/sup> at 405,600 km away. We have 0.6\u00b0 from Antares on the 27th<\/sup>. And on the 29th<\/sup>, a second southern lunistice occurs at 28.6\u00b0.<\/p>\n\n\n\n

Occultations this month include El Nath on the 14th and Antares on the 27th.<\/p>\n\n\n\n

The equinox happens on the 22nd<\/sup> at 18:20 UT. The sun will be over the equator going south.<\/p>\n","protected":false},"excerpt":{"rendered":"
