I got some pretty good pics.
The sky was clear all day overhead but looked very murky brown (Chemtrail activity signature) over Marlboroughs direction. It looked bad over that way.
At about 4.30 they began to lay trails down above Arapara Island and the chem drift began its move over Wellington.
Im pretty excited about a few of the pics, will post shortly.

Nothing fitting the sylph description was seen during this event but there were several other anomalies.
I witnessed 5-6 very short small trails earlier than when the above shots were taken, and got a photo of a jet "hightailing" it westward from the earlier spray area. I have a photo of it, and it wasnt flying on any known flight vector. (Actually I only have a pic of his contrail as he was very far away and It was hard work looking west at the time as the sun was low so I never noticed it until studying the pics.
I will upload that shot soon.
I notice you say jet. It would be good to get some more close-up shots of the jet. It is the only thing leaving trails in my area. Very quiet engines dont you agree?
Wasnt either elevate or secondfield going to film some of the skyline in infa-red?

Your trying to lead me into a discussion I am "not quite ready" to discuss openly.

I myself, and some of my closest associates have witnessed some very unusual phenomena during chemtrail events, including extraordinarly fast moving craft, silent and dissapearing "jets", blackbeams,lines, Orbs and other unidentifiable craft some of which I have personally photographed and not yet made public.
Infrared filming of the sky has commenced here in Wellington. Secondfield brought the setup around to my house on Thursday night to "showoff" and although I didnt really make a fuss about his gear at the time, I have to admit to being impressed by what he showed me. Perhaps he himself can elaborate here. I have seen some of his video captured during night filming. It is still in its development phase so I doubt there will be any major announcments concerning this particular line of investigation in the immediate future.
It works. He has been using motion detection software designed for meteorite detection and photographic capture hooked up to a modified webcam designed to film infrared. This camera is boxed with an unmodified webcamera that films in tandom to provide a type of control for the experiment.. The computer records both cameras footage when motion is detected in the sky. The results thus far are interesting.
Saw some of those trails you mentioned on saturday there samsh. Was sitting up at the Brooklyn windmill briefly in the afternoon and observed two persistant trails being laid along with regular ones several thousand feet higher in altitude dissapating within a minute or so. Sunday's observations shook me to the core. Although not an extensive operation, I feel I must mention some important occurences....
Whilst driving toward Petone (from Upper hutt) around lunchtime, I noticed a persistant 'trail' Hanging in the sky above Wellington Harbour. Deciding to take a closer look, parked at the Petone foreshore and saw what appeared to be another 'trail' forming out of wispy clouds parallel to the existing one. This new 'trail' then moved east through the first trail, of its own acccord, wiping it from the sky...low Cumulus surrounded the ranges which enclosed the harbour and this 'trail' was the only 'cloud' that was mobile. The entire process took around 30 minutes or so and after that I decided to do some shopping in Petone, at which point I turned the van around and headed back to town (north). No sooner had I did this when I saw a large, fast, low flying (<25,000ft) jet aircraft laying down a 'trail' right along the hutt valley. Pulling the van over I spied it through a pair of binoculars. It appeared to have no visible markings, was highly reflective (white) and soundless (I didnt expect to hear too much anyway as it was still at altiude). It seemed to be moving abnormally quickly. as it reached the edge of my field of veiw i moved the vehicle forward some to get another look at it. What I saw made my blood run cold. In the time it took for me to move the van forward several meters (maybe 10 seconds, max). This 'aircraft' had completely dissapeared!. The 'trail' had stopped dead in the sky above the Wainui hills. From its trajectory, it should have carried it out across Cook straight . Nothing to be seen, through bino's or otherwise. Unless it had done a 90 deg turn to the east there would've been a very high chance of still observing it. I could see where the trail started... back over Upper Hutt, and i could see where it ended.. Wainuiomata hills. It had gaps in it too. Completely off the flight vector map as well. I even sent a txt msg to the 'boys' :wink: saying "heads up theres a trailing plane headed past your window bout now" but nothing... zip...nada. She gone.
Spent the rest of the day up mt vic with the IR cam and laptop on the sky. Nothing more to be seen, no trails, persistant or otherwise. Got back to my partners in UH the next day and she told me of a massive trail over the valley that afternoon, turned the sky inside out apparently.... just one. How could anyone miss that she wondered?.
If you could get some photos of the jet would be most appreciated. Operations have been quite erratic of late so it will be a tough task. I will be interested to see some of your IR footage.
I have posted some contrail analysis charts to the Gallery. The data is from Paraparaumu between midday Friday 6 April 2007 and midday Sunday 8 April 2007. They more or less span the times that the trails referred to above were observed.
Here are the sounding times, links to the charts, and the lower boundary of the lowest contrail layer suggested by the analysis chart. The chart is for high bypass jet engines, the type of engines fitted to Air New Zealand's 737s and A320s, and QANTAS' 737s. The height is given as flight level (100s of feet, F310 is about 31000 feet) and metres, and the wind at that altitude - that is roughly the direction and speed that the contrail will drift after the plane has gone.
The usual cautions and caveats apply to the use of these things.
Anyway, the point I want to make here is that the trails observed on Friday and Saturday were jet exhaust condensation (contrails). The parallel lines are from the contrail moving west in the wind flow while another flight "puts down" a fresh trail on the same flight path. In the last photo smashdracs put up there is a short contrail from an aircraft heading west, or a bit south of west. This is probably a flight from Wellington to Melbourne (or possibly Adelaide) having climbed to its cruise altitude of about F360 somewhere over the area south of Nelson.
HOWEVER...
On the Sunday, the lower boundary of the contrail layer was probably rising from F284 at midnight to F322 at midday (and probably higher still in the afternoon). But secondfield observed an aircraft, trailing, at an altitude he estimated at less than 25000 feet, F250, below the contrail layer, and apparently "on a mission to nowhere". This is much more interesting.
If someone can identify that flight in the Flight Explorer data (or from Airways Corporation records and an OIA request), and establish that it was] at such a low altitude, and find a reliable (date, time, etc data) photo of it at the time, then it will be possible to document a genuine chemtrail spray instance. If that is the case, a report can be written up and it can be taken to the authorities with a request for an explanation.
Maybe it is, as smashdracs sigs, time to make The Man pay.

Ive checked my maps and plotted the direction of the shot etc. It appears that Hector is right (On that one).
One thing that immediately siezes my attention when observing persistant contrails is the abruptness off them. That is, they seem to have a definitive start and stop points. Many times with hard edged gaps observable in them. If the meteorlogical conditions are that erratic upstairs over an area of 10-40km in a straight line I fail to understand how an atmospheric sounding based at Paraparaumu can effectively predict or account for a wide area maybe covering 1000sq km as we have in the greater wellington region. I observed only one heavy, persistant trail last sunday, approx 1230pm straight along hutt valley, toward town (reported previously but emphasised again). The trail was seen to start north of UH (it did not stretch aver the Rimutaka's) and abruptly stopped (when the aircraft 'vanished') over the Wainuiomata hills. The 'aircraft' must've flown right off the plotted flight vector (an abrupt turn more than 90deg) for it not to be visible through bino's or otherwise. Surely there were more N/S overflights of Wgtn that day. I was so perplexed by this and sat up mt vic waiting for more trails over town all arvo. Not a bean. Hector, if an aircraft is over the land and then crosses over a body of water, can this affect the formation of contrails? Immediately?. The ones we observed from Titahi bay today did both, form over land and water, then abruptly end some distance from the shoreline. Strangely, after watching them for 30 minutes or so after formation short trails could be seen forming perpendicular to the existing ones, along their axis, with no aircraft present. Again, I didnt have my bloody camera, but those who have seen them will immediately know what im talking about. Im running a mac so hence cant have flight explorer on this machine (without some decent emulation software $), another feeble excuse, but thats why we network eh. Regards.
secondfield discussed the apparent problem of abrupt starts and stops in some of the contrails he has observed. I have already gone over this in posts in other topics. The most recent is this one ...

Read that one post now, then come back and read on.
The meteorological conditions (except perhaps the RH) up there are not erratic at all. There may be a gentle horizontal temperature gradient, and the steepness of that can be deduced from the wind shear; how much the wind speed (and direction) changes between one level and another. Except in the vicinity of a jet-stream core, and warm or cold fronts these gradients are fairly small; a degree or two in 100 km. An atmospheric sounding is fairly representative within a few hundred km, especially if you can quantify the horizontal temperature gradient and its direction. If anyone wants more information about this, I can write a little dissertation, or you can search the Internet for "thermal wind".
Basically; facing down wind, if the wind speed is INCREASING with height, the temperature will be DECREASING to your RIGHT (at the same pressure = flight level). If the wind direction is veering with height (turning more to the right), the lower temperature will be further in that direction (to the right). I hope that's clear. This applies in the Southern Hemisphere; in the NH, the directions are in the opposite sense.
The measurement of RH at cold temperatures (in the upper troposphere, where contrails occur) will continue be difficult until there is some break through in the measurement technology. (A search for that will reveal the good oil.) Until then we have to make-do with the technology we have available. Vaisala is a major manufacturer of radiosondes - visit their website and learn all about it.
If an aircraft is climbing and enters the contrail layer (where the ambient temperature is below the contrail critical temperature), the contrail will abruptly form starting at the entry point. Similarly when it descends out of the contrail layer, the contrail will abruptly cease. The aircraft being over land or water makes no difference whatever. As you said, secondfield, you saw contrails over both land and water. Even if the aircraft is flying level, it may be flying into warmer ambient air (flying up the temperature gradient). Eventually the ambient air temperature the plane is flying through goes above the contrail critical temperature, and the contrail will cease. There may be some intermittent off and on if the temperature is "undulating" a bit or if there is variations in the RH. Remember that the critical contrail temperature is the threshold - you are either over it, or not. Contrails either form or they don't (in a particular place at a particular height).
The other important thing to bear in mind is that with each aircraft that passes more and more water vapour is being introduced at the aircraft cruise altitude range. This gradually lowers the contrail critical temperature. If a flight path crosses another, or as I suspect more commonly happens in New Zealand the water vapour exhaust from one flight path is advected (blown by the wind) horizontally into another, more or less parallel flight path. This probably happens a lot over Marlborough/Wellington, and Manawatu/Wanganui.

Yes, all kinds of things can happen as contrails dissipate. Striations across, billows (like little puffs up, down or to the side), thick on one side and thin to invisible on the other, or it might remain tight and 'solid', and so on.
I'm sorry to hear about your Mac problems; I'm a PC guy. And here's a tip, whatever your preferred machine, compose and spell check in a text editor off-line, and paste into the text entry box in the Reply form (when you get back on-line and log in).
