Andrew, are you facing potentially dangerous amounts of liquid DHMO (and trace elements in suspension) accumulation (2.5cm+) on the surface of the planet at your coordinates? <br /><br />The northeastern areas of the U.S. above sea level were faced with significant layering of liquid DHMO for several sols until 48 hours ago. The local vegetation appears quite confused. <div class="Discussion_UserSignature"> </div>

I would not say dangerous amounts (during the Summer we did), but it was a nuisance,<br />enough to get wet & of course the DHMO had condensed to veil <br />the nocturnal skies, thus<br />severely depriving me of visual observations of interplanetary ice / dust ball.<br /><br />Today, it could not be more different. It is almost dark here now & I am going out to the coast to<br />get a clear N E view over the English Channel towards France.<br /> <br />I will be back later to report.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

I like viewing it a little before 2 A.M. (daylight time), when it is a little north of being directly overhead -- at D.C. latitude.

Yes, it is. In Perseus' "left thigh".<br /><br />My own favorite viewing time/angle for the West Coast is between 20:30 and 22:30 PDT. That puts it in the north eastern sky, Capella (in Auriga, under Perseus)having risen enough to give a clear marker star. The advantages to earlier viewing are: The moon is still obstructed for me (that advantage goes away by 21:00 right now at my site), and the shallower angle makes both telescope and binocular viewing much more comfortable. At the same time, it's high enough to clear our worst light pollution, and any smog/haze we might have. <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>

Thanks MeteorWayne,<br /><br />I sure did.<br /><br />I went to a small seaside town called Dymchurch on the Kent coast. Got to Folkestone, where <br />was headed intitially & the Dymchurch bus was just sitting there @ the bus station, so I got on<br />(much less light pollution @ Dymchurch).<br /><br />Yes Comet 17P/Holmes was there for the taking. It was much larger & brighter than I had expected.<br /><br />Perseus did look odd, that much was even obvious in the light polluted skies of Ashford.<br /><br />I took loads of pictures, will post links here when I get them back (will get the film<br />processed & a CD Rom made up tommorow).<br /><br />Took some of Holmes next to Mirfak & the Alpha Persei cluster. 50mm lens & 220mm zoom.<br /><br />It was incredibly beautiful. The waning Gibbous moon was low over the English Channel,<br />there were high Cirrus Clouds to the North & also there was a multicoloured Moon Arc <br />to the left & took several images of that too.<br /><br />Perseus was in the clear & there was Holmes & I was quite literally amazed at how<br />big & bright it was.<br /><br />Mars rose above the Kent coast. It really was a good trip.<br /><br />The dihydrogen monoxide ice veils @ the tropopause vacated the area, leaving the <br />sky almost 100% clear after a while. Got some nice shots of the moon over the Kent coast. <br /><br />When the pictures are developed & CD rom made up, I will link them to this thread <br />(tomorrow hopefully).<br /><br />I also took in Comet 17P/Holmes in 7 x 50 binoculars & the colour was strange, sort of<br />greenish, a bit like Comet 1996 B2/Hyakutake in the Spring of 1996??? Cyanogen????<br /><br />I will go again on Thursday (day off then) as the weather still looks favourable then.<br /><br />The moon will have waned to 58% by then & rising @ 22:17 UT, so should be a much <br />darker sky.<br /><br />Weather forecast looks crap here for Friday, so I will go on Thursday.<br /><br />BTW today's APOD: <</safety_wrapper> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

I hope they come out, should do.<br /><br />I've got three frames left, so will take some Autumn shots on the way to work <br />tommorow to finish off the film.<br /><br />Fantastic comet, somewhat larger & brighter than I had expected.<br /><br />I wonder if we will ever find out why Holmes has brightened by such an enormous amount??<br /><br />Apparently the Nucleus is thought to be only 3.4 kilometres across, mountain sized.<br /><br />So something really weird has happened for Holmes to appear so bright from so far away<br />being such a small comet!!! <br /><br />Anyway good night all, I'm off to bed now.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

right now, roughly above the moon. make a straight line between the moon and a contellation that looks like a "W." the comet has a yellowish hue. check this link to see exactly where it is. pic is facing towards the east. moon is on far left. Follow it up to the W, divide, youll see the yellow, hazy comet. its small; doesnt look like much more than a star, really, and not extremely bright, but its easy to spot with the eye.<br /><br />http://s5.photobucket.com/albums/y193/usn_skwerl/?action=view&current=ohio.jpg <br /><br />additionally, use the three stars making the triangle to the right as an arrow, facing away from the comet. if it's dark enough, you cant miss the triangle constellation. <div class="Discussion_UserSignature"> </div>

Just look for the three stars forming the skinny triangle to split the difference between the "W" constellation, and the moon, kind of (the moon isnt in the same spot as last night, it's a little further down towards the horizon, a little further from the "W". Once you do that, you can use the binocs to spot the hazy yellow dot. It's the only noticeably yellow dot in that area. That'll be the comet <img src="/images/icons/laugh.gif" /><br /> <div class="Discussion_UserSignature"> </div>

Yup!<br /><br />Look for it in the same place. Left thigh of Perseus. Below Mirfak, above Capella. Figure a rise time of something like 20:30 local time. Depending upon how much of the horizon you can see, plan on starting to look for it around 21:30-22:30 local. Visible until close to daybreak. <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>

To answer a common question, yes it is visible from the entire northern hemisphere.<br /><br />In fact, if you live above 40 degrees north latitude, it is currently circumpolar, i.e. it never goes below the horizon.<br /><br />If you closer to the equator than 50 degrees south, it is visible for part of the early morning hours, low on the horizon.<br /><br />For the are between, it is visible for a good part of the night.<br /><br /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

That APOD picture is really cool. I wonder what the 28-29th look like.<br />Last night I though it looked even bigger and brighter than it did on Sunday night. I attributed it to the moon being farther away. But it looks like it IS bigger.<br /><br />How long will it be before it starts dispersing? I'm planning on driving out to dark skies Thursday night, but might go tonight if it's going to start fading.

There's really no way to tell. This is a rather unprecedented outburst for a comet at that distance from the sun.<br />My impression last night was it was bigger, but dimmer, I estimated about mag +3.2. Also the central condensation (through the scope) was not as bright or distinct as two nights ago. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Either way, it's something unexpected, normally invisible to the naked eye, especially in the city. And also it's just pretty friggin cool. <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> </div>

Wayne: I agree. My estimation was closer to +3 (it seemed almost exactly the same as Delta Per, which is +3.01).<br /><br />The coma seemed larger, though I may have just been able to see more of it with the moon below the horizon. The central brightening still seemed fairly distinct and bright, but perhaps slightly less so than the day before.
