It spends the month in the Sagittarius, passing across the Teapot asterism from the 12th to the 20th.<\/p>\n\n<p class=\"article-full-body sans-serif\">As November opens, a small telescope reveals Venus shaped like a quarter Moon, 26 arcseconds across. It grows as it heads towards inferior conjunction, ending the month 38 arcseconds across.<\/p>\n\n<h4 class=\"article-subhead\"><strong>Stars and constellations<\/strong><\/h4>\n\n<p><strong>Equipment: Naked eye<\/strong><\/p>\n\n<p class=\"article-full-body sans-serif\">November evening skies from mid-latitude Southern Hemisphere locations offer a barren but unique view of the heavens. All around you the Milky Way is hugging the horizon. Above is an unobscured view of the half of the Universe that lies below (south of) the galactic plane. Besides the local stars and globular clusters this is the domain of the galaxies, with three obvious members of the Local Group, the two Magellanic Clouds (high in the south) and M31 (low in the north).<\/p>\n\n<h4 class=\"article-subhead\"><strong>The planets<\/strong><\/h4>\n\n<p><strong>Equipment: Naked eye<\/strong><\/p>\n\n<p class=\"article-full-body sans-serif\">Start with Venus, <span class=\"has-inline-color has-ccp-black-color\">above it is <\/span>Saturn and then Jupiter, all conspicuous in the western sky. Saturn is not as bright as Jupiter, but they are both prominent in Capricornus. The outermost planets are<span> also on view; Neptune is transiting (due north) during twilight, followed by Uranus, which transits about midnight. A borderline naked-eye object, Uranus\u2019s attainment of mag. +5.6 makes it a better target.<\/span><\/p>\n\n<h4><strong>Deep-sky objects<\/strong><\/h4>\n\n<p><strong>Equipment: Binoculars<\/strong><\/p>\n\n<p id=\"block-c1ed39fc-bf17-4081-8a50-8de741462026\">Mira (Omicron (o) Ceti), RA 2h 19.3m, dec. -2\u00b0 59\u2019, is a brilliant variable star and the brightest long period pulsatingtype variable. It varies from around 3rd magnitude down to 8th magnitude, with the full cycle taking 330 days. Mira\u2019s peak in 2021 is expected in September and by November it is likely to have faded to about mag. +4.5. To help you watch its drop in brightness, a plot of magnitude measurements and a finder chart with comparison stars can be downloaded from the AAVSO website. Mira\u2019s next minimum is expected in March 2022 (close to conjunction).<\/p>\n\n<p><strong>Equipment: Small\/medium telescope<\/strong><\/p>\n\n<p id=\"block-8e3b4af8-032f-4803-aa67-1d55059eea26\">Located just 1.7\u00b0 west of Mira is a pretty 6th magnitude double star, 66 Ceti (RA 2h 12.8m, dec. -2\u00b0 24\u2019). The component stars are mag. +5.7 and +7.7, appearing yellow and white respectively, separated by a comfortable 17 arcseconds.<\/p>\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Take in a parade of evening planets, enjoy Local Group galaxies and search for binary star Mira<\/p>\n","protected":false},"author":24,"featured_media":25743,"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":"November-2021","purple_custom_meta_purple_source_issue":"November-2021","purple_external_id":"November-2021-100-1","purple_custom_meta_purple_external_id":"November-2021-100-1","purple_issue_code":"|0000086546||","purple_custom_meta_purple_issue_code":"|0000086546||","purple_android_product":"com.im.skyatnight.198","purple_custom_meta_purple_android_product":"com.im.skyatnight.198","purple_ios_product":"com.im.skyatnight.198","purple_custom_meta_purple_ios_product":"com.im.skyatnight.198","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\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C.jpg","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\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C.jpg",2048,2047,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C-300x300.jpg",300,300,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C-768x768.jpg",768,768,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C-1024x1024.jpg",800,800,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C-1536x1536.jpg",1536,1536,true],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2021\/10\/7ZXYR3IOH2NP818PAK566O00LL3C.jpg",2048,2047,false]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"Take in a parade of evening planets, enjoy Local Group galaxies and search for binary star Mira","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/25423"}],"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=25423"}],"version-history":[{"count":4,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/25423\/revisions"}],"predecessor-version":[{"id":25888,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/25423\/revisions\/25888"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media\/25743"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media?parent=25423"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/categories?post=25423"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/tags?post=25423"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
