One is the Gamma Normids, active between 25 February and 28 March, and peaking around 15 March. Even at maximum only a few meteors are seen per hour, but their colour \u2013 white, yellow, and orange with some leaving trains \u2013 make the wait worthwhile, and their brightness helps overcome the unfortunate presence of the third quarter Moon in the morning sky during this year\u2019s peak. <\/p>\n\n<h4 class=\"sans-serif article-subhead\"><strong>THE PLANETS <\/strong><\/h4>\n\n<p class=\"article-full-body sans-serif\"><strong>Recommended equipment: Naked eye<\/strong><\/p>\n\n<p class=\"article-full-body sans-serif\">The first week of March sees brilliant <span>Jupiter and Venus together low in the early twilight western sky. They soon separate, with Jupiter dropping towards the Sun as much brighter Venus slowly rises. Uranus spends the month dropping towards Venus, coming within 1.4\u00b0 on 31 March before leaving the evening sky. Mars spends March in the northwest, departing around 23:00. Saturn appears out of the Sun\u2019s glow, rising about two hours before dawn by month\u2019s end.<\/span><\/p>\n\n<h4 class=\"sans-serif article-subhead\"><strong>STARS AND CONSTELLATIONS <\/strong><\/h4>\n\n<p class=\"article-full-body sans-serif\"><strong>Recommended equipment: Naked eye<\/strong><\/p>\n\n<p class=\"article-full-body sans-serif\">High in the southern evening sky is the ship Argo, of Jason and the Argonauts fame. Today, it has been broken up into the constellations Puppis (deck), Vela (sails) and Carina (keel), linked by the False Cross asterism. From northern latitudes all that is visible are the sails, even at maximum altitude; the rest of the ship is below the horizon. Earth\u2019s precession caused this \u2018sinking\u2019 \u2013 around 3,500 years ago the entire ship clearly sailed the Middle Eastern horizon. <\/p>\n\n<section class=\"wp-block-uagb-section uagb-section__wrap uagb-section__background-color uagb-block-98c89acd-b214-4ee1-9e40-ee484db74a6b article-boxout\"><div class=\"uagb-section__overlay\"><\/div><div class=\"uagb-section__inner-wrap\">\n<h4 class=\"sans-serif article-subhead\"><strong>DEEP\u2013SKY OBJECTS <\/strong><\/h4>\n\n\n\n<p class=\"article-full-body sans-serif\"><strong>Recommended equipment: Small\/medium telescope<\/strong><\/p>\n\n\n\n<p class=\"article-full-body sans-serif\">This month we take a trip to the constellation of Cancer. The bottom star of the Crab\u2019s main Y-shaped asterism of stars is 4th-magnitude Iota (\u03b9) Cancri. Although an impressive double star itself, our target lies 4\u00b0 to the west. Phi<sup>1<\/sup>(\u03c6<sup>1<\/sup>) Cancri (RA 4h 20.0m, dec. -54\u00b0 56\u2019) is a nice yellow-coloured mag. +5.5 star which contrasts well with its white companion Phi<sup>2<\/sup> (\u03c6<sup>2<\/sup>), located 1\u00b0 above (south). Phi<sup>2<\/sup> is a truly magnificent double with matching <span>mag. +6.2 white stars, separated by 5 arcseconds, looking like car headlights.<\/span><\/p>\n\n\n\n<p class=\"article-full-body sans-serif\"><strong>Recommended equipment: Large telescope<\/strong><\/p>\n\n\n\n<p class=\"article-full-body sans-serif\">Next up, a jump to the southern end of Cancer, near the border with Hydra, to the impressive spiral NGC 2775 (RA 9h 10.3m, dec. +7\u00b0 02\u2019). At mag. +10.2, this galaxy has an obvious, elongated core with a star-like nucleus. Its surrounding halo (3 x 2 arcminutes) is stunning, being bright with some minor mottling. <\/p>\n<\/div><\/section>\n\n<p class=\"footer\">CHART: PETE LAWRENCE<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Eyes peeled for the colourful, elusive Gamma Normids, and discover stunning targets in Cancer <\/p>\n","protected":false},"author":24,"featured_media":41830,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ub_ctt_via":"","purple_page_number":"100","purple_custom_meta_purple_page_number":"100","purple_seq_number":"1","purple_custom_meta_purple_seq_number":"1","purple_source_article":"article_100-1.xml","purple_custom_meta_purple_source_article":"article_100-1.xml","purple_source_issue":"March-2023","purple_custom_meta_purple_source_issue":"March-2023","purple_external_id":"March-2023-100-1","purple_custom_meta_purple_external_id":"March-2023-100-1","purple_issue_code":"|0000086562||","purple_custom_meta_purple_issue_code":"|0000086562||","purple_android_product":"com.im.skyatnight.214","purple_custom_meta_purple_android_product":"com.im.skyatnight.214","purple_ios_product":"com.im.skyatnight.214","purple_custom_meta_purple_ios_product":"com.im.skyatnight.214","purple_web_product":"","purple_custom_meta_purple_web_product":"","purple_publication_id":"075fab74-0a21-4201-866a-899d6c41c40c","purple_migrated":"","kt_blocks_editor_width":""},"categories":[22],"tags":[14],"featured_image_src":"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1.png","author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"acf":{"readingTimeMinutes":"3","apple_news_title":""},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1.png",3317,3317,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1-150x150.png",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1-300x300.png",300,300,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1-768x768.png",768,768,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1-1024x1024.png",800,800,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1-1536x1536.png",1536,1536,true],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/02\/Layer-2-1-2048x2048.png",2048,2048,true]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"Eyes peeled for the colourful, elusive Gamma Normids, and discover stunning targets in Cancer","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/41811"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/comments?post=41811"}],"version-history":[{"count":7,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/41811\/revisions"}],"predecessor-version":[{"id":42295,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/41811\/revisions\/42295"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media\/41830"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media?parent=41811"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/categories?post=41811"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/tags?post=41811"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
