\u00a0So I looked closely at the other two images, which it quickly became apparent that they were all three different parts of the sky. \u00a0What&#8217;s more, they&#8217;re all right next to each other&#8211;now this is getting interesting! \u00a0I began to wonder, could this be some kind of erratic path that it took as it broke up? \u00a0Let&#8217;s stitch them together into a mosaic to see what it looks like. \u00a0The results looked puzzling when I first constructed the mosaic:<br \/>\n<a href=\"https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-227\" src=\"https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4.jpg\" alt=\"02a58019_meteor-4\" width=\"1856\" height=\"1880\" srcset=\"https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4.jpg 1856w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4-296x300.jpg 296w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4-1011x1024.jpg 1011w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4-768x778.jpg 768w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4-1516x1536.jpg 1516w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02a58019_meteor-4-1200x1216.jpg 1200w\" sizes=\"auto, (max-width: 1856px) 100vw, 1856px\" \/><\/a><br \/>\nThe discontinuities made sense, because of time difference between images, but I wasn&#8217;t sure if the object had split up and that&#8217;s what was causing the big looped trail in the third image. \u00a0But wait a minute&#8211;ahah! \u00a0We use an &#8216;auxiliary&#8217; camera on the ATLAS telescopes that matches\u00a0in exposure length and timing to the main camera. \u00a0So I went to pull those images and chucked them together. \u00a0Finally, a coherent picture of what happened!<br \/>\n<a href=\"https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-229\" src=\"https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2.jpg\" alt=\"02x58019_meteor-2\" width=\"1580\" height=\"1407\" srcset=\"https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2.jpg 1580w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2-300x267.jpg 300w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2-1024x912.jpg 1024w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2-768x684.jpg 768w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2-1536x1368.jpg 1536w, https:\/\/blog.fallingstar.com\/wp-content\/uploads\/2017\/09\/02x58019_meteor-2-1200x1069.jpg 1200w\" sizes=\"auto, (max-width: 1580px) 100vw, 1580px\" \/><\/a><br \/>\nIn summary, to explain what you&#8217;re looking at here: \u00a0the first image contains the streak; the second image contains the large smoke trail that had drifted slightly up in the 20 or 30 second period between images; and the third image at top shows the smoke trail after it had drifted for a little over 10 minutes.<br \/>\n&nbsp;<br \/>\n&nbsp;<br \/>\n&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As I was doing my morning routine, which lately includes sifting through the previous night&#8217;s exposures for various reasons, a particular set of images caught my eye with one being exceptionally flashy: Now, what on Earth could that be, I thought to myself, with mouth agape and eyes wide. \u00a0Then, I spotted the other two &hellip; <a href=\"https:\/\/blog.fallingstar.com\/?p=225\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">ATLAS Sees a Meteor!<\/span> <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-225","post","type-post","status-publish","format-standard","hentry","category-topics"],"_links":{"self":[{"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=\/wp\/v2\/posts\/225","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=225"}],"version-history":[{"count":0,"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=\/wp\/v2\/posts\/225\/revisions"}],"wp:attachment":[{"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=225"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=225"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.fallingstar.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=225"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
