Over the coming days, as they orbit, they will rise to 550 kilometres.<\/h3>\n<h4><strong>There&#8217;s still a chance you could spot them, too. The keys are dark skies, patience and binoculars.<\/strong><\/h4>\n<p>How to see them<\/p>\n<p>First, you need to understand about visual magnitude. Astronomers have come up with a way of measuring the brightness of objects in the night sky.<\/p>\n<p>The brightness of celestial objects is on a scale that goes from the very brightest \u2014 the sun \u2014 to the dimmest. And the lower the number (negative values), the brighter the object.<\/p>\n<p>As you can see by the chart above, the visual magnitude limitation for the human eye is an object with a magnitude of +6, and that&#8217;s in dark-sky locations, away from the pollution of city lights. Within a city, that drops to +3.<\/p>\n<p>The brightness of the Starlink satellites over Toronto, for example, range from roughly +6 to +3, right on the visual limit in light-polluted skies.<\/p>\n<p>So, if you want to see the satellites \u2014 which will have spread out a bit more by now \u2014 get to a dark-sky location, away from city lights. They won&#8217;t be as bright as in Langbroek&#8217;s video, since he captured them with a low-light camera.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&amp;amp;amp;lt;span data-mce-type=&#8221;bookmark&#8221; style=&#8221;display: inline-block; width: 0px; overflow: hidden; line-height: 0;&#8221; class=&#8221;mce_SELRES_start&#8221;&amp;amp;amp;gt;\ufeff&amp;amp;amp;lt;\/span&amp;amp;amp;gt; Link to Marco Langbrocks Vimeo webpage Link to Marco Langbrocks webpage Link to Video of the launch of the 60 satellites last week, SpaceX launched 60 satellites into space &hellip; <a href=\"http:\/\/sd41blogs.ca\/ignasv\/2019\/06\/16\/look-up-look-way-up-look-just-a-little-bit-up-and-youll-see-star-linked-satellites\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":519,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/posts\/5356"}],"collection":[{"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/users\/519"}],"replies":[{"embeddable":true,"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/comments?post=5356"}],"version-history":[{"count":14,"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/posts\/5356\/revisions"}],"predecessor-version":[{"id":5372,"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/posts\/5356\/revisions\/5372"}],"wp:attachment":[{"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/media?parent=5356"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/categories?post=5356"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/sd41blogs.ca\/ignasv\/wp-json\/wp\/v2\/tags?post=5356"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
