FIRE IN THE SKY: The Electric Universe - Comet LINEAR Suddenly And Unexpectedly Brightens With Outburst, Puzzling Astronomers?!

<div style="text-align: justify;"><b><span style="color: yellow;">November 05, 2013 - SPACE </span></b>- It’s swiftly becoming an “all comets, all the time” sort of observing season. The cyber-ink was barely dry on our “How to Spot <a href="http://www.universetoday.com/105582/how-to-see-this-seasons-other-comet-2pencke/" target="_blank">Comet 2P/Encke</a>” post this past Monday when we were alerted to <i>another</i> comet that is currently in the midst of a bright outburst.<br /><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-ZsyLMDVVX-k/Unk1rjbOE9I/AAAAAAABNDo/P1zCBqTzSbY/s1600/cometlinear01.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-ZsyLMDVVX-k/Unk1rjbOE9I/AAAAAAABNDo/P1zCBqTzSbY/s1600/cometlinear01.jpg" /></a></div><br /><br />That comet is C/2012 X1 LINEAR. Discovered on December 8^th, 2012 by the ongoing Lincoln Near Earth Asteroid Research (<a href="http://www.ll.mit.edu/mission/space/linear/ETS.html" target="_blank">LINEAR</a>) survey based in Socorro, New Mexico, <a href="http://www.aerith.net/comet/catalog/2012X1/2012X1.html" target="_blank">Comet X1 LINEAR</a> was expected to peak out at about +12^th magnitude in early 2014.<span id="more-105678"></span><br /><br />That all changed early this week, when amateur observers began to report a swift change in brightness for the otherwise nondescript comet. Japanese observer Hidetaka Sato reported the comet at magnitude +8.5 on October 20^th, a full 5.5 magnitudes above its expected brightness of +14. Remember, the <a href="http://csep10.phys.utk.edu/astr162/lect/stars/magnitudes.html" target="_blank">magnitude scale</a> is logarithmic, and the lower the number, the brighter the object. Also, 5 magnitudes represent an increase in brightness of 100-fold.<br /><br /><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://1.bp.blogspot.com/-y3RyadDro4w/Unk1y4rlQdI/AAAAAAABNDw/1N2R3WstmRU/s1600/cometlinear02.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" src="http://1.bp.blogspot.com/-y3RyadDro4w/Unk1y4rlQdI/AAAAAAABNDw/1N2R3WstmRU/s1600/cometlinear02.jpg" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Comet C/2012 X1 LINEAR as imaged by Howes, Guido & Nicolini on Monday, October 21st. <br />(Credit: <a href="http://remanzacco.blogspot.it/2013/10/outburst-of-comet-c2012-x1-linear.html" target="_blank">remanzacco.blogspot</a>).<br /> </td></tr></tbody></table><br />Astronomers Nick Howes, Martino Nicolini and Ernesto Guido used the remote 0.5 metre iTelescope based in New Mexico on the morning of Monday, October 21^st to <a href="http://remanzacco.blogspot.it/2013/10/outburst-of-comet-c2012-x1-linear.html" target="_blank">confirm the outburst</a>. Other amateurs and professional instruments are just now getting a look at the “new and improved” Comet X1 LINEAR low in the dawn sky. Romanian amateur observer Maximilian Teodorescu noted on yesterday’s <a href="http://www.spaceweather.com/" target="_blank">Spaceweather</a> that the comet was not visible through his 4.5 inch refractor, though it was easy enough to image.<br /><br />Comet X1 LINEAR currently sits in the constellation Coma Berenices about mid-way between the stars Diadem, (<a href="http://en.wikipedia.org/wiki/Alpha_Comae_Berenices">Alpha Coma Berenices</a>) and Beta Coma Berenices. Shining at +8.5 magnitude, the coma is about 85” across with a 10” bright central region. This gives X1 LINEAR the appearance of an unresolved +8th magnitude globular cluster. In fact, a classic globular and a star party fave known as M3 lies about 8 degrees away at the junction of the constellations Canes Venatici, Boötes and Coma Berenices. M3 shines at +7th magnitude and will make a great contrast on the hunt for the comet. <br /><br /><br /><span style="color: lime;"><b>WATCH:</b></span> Comet C/2012 X1 (LINEAR) Outburst. <br /><div style="text-align: center;"><br /><iframe allowfullscreen="" frameborder="0" height="321" src="https://www.youtube.com/v/95wvUxUQqxo?showinfo=0&version=3" width="570"></iframe></div><br /><br /><br />Unfortunately, the window of time to search for the comet is currently short. From latitude 30 degrees north, the comet sits only 15 degrees about the northeast horizon 30 minutes before local sunrise. The situation is a bit better for observers farther to the north, and mid-November sees the comet 20 degrees above the horizon in the dawn sky. <br /><br />Comet X1 LINEAR is currently covering 40’ (2/3rds of a degree, or 1 1/3 the size of a Full Moon) a day, and will spend most of the month of November in the constellation Boötes. Keep in mind, X1 LINEAR is currently still on brightening trend “with a bullet.” Revised light curves now show it on track to reach magnitude +6 near perihelion early next year, but further brightening could still be in the cards for this one. Remember <a href="http://en.wikipedia.org/wiki/Comet_Holmes">Comet 17P/Holmes</a> a few years back? That one jumped from an uber-faint +17th magnitude to a naked eye brightness of +2.8 in less than 48 hours. <br /><br /><br /><span style="color: lime;"><b>WATCH:</b></span> Astrophysicist Wal Thornhill explains comets and cometary displays from an Electric Universe standpoint. <br /><div style="text-align: center;"><br /><iframe allowfullscreen="" frameborder="0" height="321" src="https://www.youtube.com/v/cRRzyI-yRko?showinfo=0&version=3" width="570"></iframe></div><br /><br /><br />Comet X1 LINEAR will reach a perihelion of 1.6 Astronomical Units (A.U.s) from the Sun on February 21st, 2014, and pass 1.6 A.U.s from the Earth around June 28th, 2014.
