The planet reaches dichotomy this month, passing from crescent through to gibbous phase. Dichotomy is the term used to indicate when a planet (or the Moon) reaches the 50 per cent phase. This month, dichotomy should occur on 21 March, but due to what\u2019s known as the \u2018phase anomaly\u2019, through the eyepiece of a telescope Venus will appear half-lit a few days later than this theoretical prediction. The phase anomaly is believed to be caused by how the planet\u2019s thick atmosphere scatters sunlight. Take a look through a telescope and make an estimate of the phase in the run up towards and beyond the 21st.<\/p>\n\n<div class=\"no-tts wp-block-image\"><figure class=\"no-tts alignright is-resized\"><img loading=\"lazy\" src=\"https:\/\/dj9jqhxgw9833.cloudfront.net\/uploads\/sites\/77\/2022\/02\/eec03b6f-55cb-4dcb-8bbc-9cd7fbb338b3.jpg\" alt=\"\" class=\"no-tts wp-image-29017\" width=\"370\" height=\"370\" srcset=\"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/eec03b6f-55cb-4dcb-8bbc-9cd7fbb338b3.jpg 613w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/eec03b6f-55cb-4dcb-8bbc-9cd7fbb338b3-300x300.jpg 300w, https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2022\/02\/eec03b6f-55cb-4dcb-8bbc-9cd7fbb338b3-150x150.jpg 150w\" sizes=\"(max-width: 370px) 100vw, 370px\" \/><figcaption>Venus should reach a 50 per cent phase <br\/>around 21 March, but may appear like this later<\/figcaption><\/figure><\/div>\n\n<p class=\"article-full-body sans-serif\">Venus drops in brightness over March, but only by a fifth of a magnitude.

It appears best at the month\u2019s start with a darker sky.<\/p>\n\n<p class=\"article-full-body sans-serif\">Mars and Saturn appear close to Venus. Saturn will be too close to the Sun to see properly at the month\u2019s start, but it<span> will be visible with Venus and Mars at the month\u2019s end.

On the 1st it shines at mag. \u20130.1, lies 2\u02da southwest of mag. +0.9 Saturn and rises 30 minutes before the Sun.<span> That offset deteriorates over the following days, and as a consequence, from the UK at least, Mercury is unlikely to be seen with the naked eye over the rest of the month.<\/span><\/p>\n\n<h4 class=\"article-subhead\"><strong>Mars<\/strong><\/h4>\n\n<p class=\"article-full-body sans-serif\"><strong>Best time to see:<\/strong> 31 March, 50 minutes before sunrise<br><strong>Altitude:<\/strong> 3\u02da (very low)<br><span><strong>Location:<\/strong> Capricornus<\/span><br><span><strong>Direction:<\/strong> Southeast <\/span><\/p>\n\n<p class=\"article-full-body sans-serif\"><span>Mars is visible in the morning sky as a mag. +1.3 object rising 90 minutes before the Sun on the 1st, when it appears 5\u02da below mag. \u20134.4 Venus. Over the next few mornings, Mars and Venus appear to converge, both planets appearing separated by just 4\u02da on the 12th. A lovely, albeit rather low, triangular grouping of Mars, Venus and Saturn can be seen low above the southeast horizon 40 minutes prior to sunrise on the 24th. By the 31st, Mars will have brightened to mag. +1.1 and rises 80 minutes before the Sun. The Mars, Saturn and Venus triangle will be contained to an area less than 6\u02da across on 31 March.<\/span><\/p>\n\n<p class=\"article-full-body sans-serif\">Through an eyepiece Mars is a bit disappointing, appearing to have an apparent diameter of 5 arcseconds at the month\u2019s end. However, this will change during the year as Mars approaches opposition in early December 2022.<\/p>\n\n<h4 class=\"article-subhead\"><strong>Jupiter<\/strong><\/h4>\n\n<p class=\"article-full-body sans-serif\">Jupiter reaches solar conjunction on 5 March and despite drawing away from the Sun\u2019s position rapidly, is unlikely to be seen this month.

Its placement in the sky isn\u2019t very optimal at present, the planet not gaining much altitude despite rising at a reasonable time before the Sun. If you have a flat southeast horizon, look out for mag. +0.9 Saturn, mag. +1.1 Mars and mag. -4.2 Venus together between 22\u201331 March. A thin, 18%-lit waning crescent Moon sits below the trio on the morning of the 28th.<\/p>\n\n<h4 class=\"article-subhead\"><strong>Uranus<\/strong><\/h4>\n\n<p class=\"article-full-body sans-serif\"><strong>Best time to see:<\/strong> 1 March, 19:50 UT<br><strong>Altitude:<\/strong> 33\u02da<br><strong>Location:<\/strong> Aries<br><strong>Direction:<\/strong> West-southwest<\/p>\n\n<p class=\"article-full-body sans-serif\">Mag. +7.9 Uranus may be seen 30\u02da above the west-southwest horizon as true darkness arrives on the 1st. A 17%-lit waxing crescent Moon sits 6.5\u02da to the southwest of Uranus on the evening of the 6th, and as a 25%-lit waxing crescent, 6\u02da to the planet\u2019s east on the 7th. By mid-March, Uranus appears a fraction over 20\u02da up above the western horizon as true darkness descends, but by the month\u2019s end it falls to just 8\u02da. As a result, March marks the end of the current observational window for this distant world.<\/p>\n\n<h4 class=\"article-subhead\"><strong>Neptune<\/strong><\/h4>\n\n<p class=\"article-full-body sans-serif\">Neptune is in conjunction with the Sun on 13 March; consequently, the planet is not visible this month.<\/p>\n\n<section class=\"wp-block-uagb-section uagb-section__wrap uagb-section__background-undefined uagb-block-7bdd666f-77f3-486e-bd97-9422e8d2700e article-boxout\"><div class=\"uagb-section__overlay\"><\/div><div class=\"uagb-section__inner-wrap\">\n<h4 class=\"article-subhead\">More <strong>ONLINE <\/strong><\/h4>\n\n\n\n<p class=\"article-full-body sans-serif\"><strong>Print out observing forms for recording planetary events<\/strong><\/p>\n<\/div><\/section>\n\n<h4 class=\"has-text-align-center article-subhead\">The planets in March<\/h4>\n\n<p class=\"has-text-align-center article-full-body sans-serif\"><strong>The phase and relative sizes of the planets this month.
