<p>The star Mira ("The Wonderful", omicron Ceti)&nbsp;will be returning to (or probably has already returned to) visibility with the unaided eye. It will be visible shortly after sunset in the Constellations Cetus, just below the lower point of the "V" of Pisces. Mira is the brightest periodic variable in the sky that is not visible to the naked eye for part of its cycle. It is also the star that was shown a few years ago to have a long tail (not visible to the eye) as it plows through the galactic interstellar gas.</p><p>From Wiki:&nbsp;</p><p>"In 1638 Johann Holwarda determined a period of the star's reappearances, eleven months; he is often credited with the discovery of Mira's variability. Johannes Hevelius was observing it at the same time and named it "Mira" (meaning "wonderful, astonishing") in 1662's <em>Historiola Mirae Stellae</em>, for it acted like no other known star. Ismail Bouillaud then estimated its period at 333 days, less than one day off the modern value of 332 days (and perfectly forgivable, as Mira is known to vary slightly in period, and may even be slowly changing over time"</p><p>If it ever clears here in NJ, I will let you all know when I have spotted it for the first time in this cycle, unfortunately lousy weather has prevented that. The peak brightness is expected within the next two weeks.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

<p>I took a peek to see about photo ops on the two stars mentioned here.&nbsp; Mira is good for me early in the evening, about 9pm she'll be up high out of the muck.&nbsp; La Superba is the opposite - about 3AM.&nbsp; La Superba is surrounded by awesome objects though.</p><p>&nbsp;</p><p>I think if I shot wide-angle with her basically center, I should be able to get her, M106, M40, M101, M51, M63, M64, M3, and maybe M53 or Arcutrus in the shot.&nbsp; Depends a lot on how much magnification I need for a good photo of her.</p> <div class="Discussion_UserSignature"> <p>.</p><p><font size="3">bipartisan</font>  (<span style="color:blue" class="pointer"><span class="pron"><font face="Lucida Sans Unicode" size="2">bī-pär'tĭ-zən, -sən</font></span></span>) [Adj.]  Maintaining the ability to blame republications when your stimulus plan proves to be a devastating failure.</p><p><strong><font color="#ff0000"><font color="#ff0000">IMPE</font><font color="#c0c0c0">ACH</font> <font color="#0000ff"><font color="#c0c0c0">O</font>BAMA</font>!</font></strong></p> </div>
