Today Mercury will be at maximum eastern elongation, as high in the evening sky as it will appear for this current apparition. After today the planet will slide back into the sunset, passing through inferior conjunction on May 30th and reappearing in the dawn during the first weeks of June.

The planet Mercury is starting an evening apparition. The planet should become visible this week just above the fading glow of the setting Sun as a magnitude -1 object. The planet is moving about 1° further from the Sun and higher in the sunset each day, reaching a maximum elongation of 21° on May 6th.
Mercury at Superior Conjunction
Today Mercury passes through superior conjunction, passing behind the Sun as seen from the Earth. The planet will appear in the sunset in ten days or so, reaching maximum elongation on May 7th.
Mercury at Maximum Elongation
Today Mercury will be at maximum western elongation, as high in the morning sky as it will appear for this current apparition. After today the planet will slide back into the dawn, passing through superior conjunction on April 9th to reappear in the evening sky around the end of April.
Mercury Appears in the Dawn
The planet Mercury is starting a morning apparition. The planet should become visible this week just above the dawn as a magnitude -1 object. The planet is moving more than 1° further from the Sun and higher in the morning sky each day, reaching a maximum elongation of 27° on February 24th. This will be the best morning apparition for Mercury in 2015.
Mercury at Inferior Conjunction
Today the planet Mercury passes through inferior conjunction, passing between the Sun and the Earth. In a week or so the planet will again be visible in the dawn sky, climbing higher each day. Maximum elongation will occur February 24th.
Mercury at Maximum Elongation
Today Mercury will be at maximum eastern elongation, as high in the evening sky as it will appear for this current apparition. After today the planet will slide back into the sunset, passing through inferior conjunction on January 30th and reappearing in the dawn during the first weeks of February.
Mercury and Venus
Mercury and Venus will be in a close conjunction this evening. While the pair has been drawing closer for the last week, tonight will see them at their closest, about 38′ separation.
Look for the bright planet Venus low in the sunset. Mercury will slightly down and to the north of Venus. A separation of 38′ is just a bit more that the width of the full Moon. Both objects are fairly bright, with Venus shining at -3.9 magnitude and Mercury at -0.7. Bright enough to be quite obvious, the pair will be 17° above the horizon at sunset.
Over the coming week the pair will slightly separate. Mercury will be at maximum elongation on January 14th, after which it will begin its slide back into the sunset.
Mercury and Venus
Over the next week Mercury and Venus will rendezvous in the sunset. This evening will see the two separated by 48′, well under one degree. This will close to about 38′ on the evening of January 10th, just a little over the width of a full Moon apart. Both objects are fairly bright, with Venus shining at -3.9 magnitude and Mercury at -0.7. Bright enough to be quite obvious, the pair will be 17° above the horizon at sunset.
