Re: [TCML] Color photos of Phantom Streams and DC phenomena



Hi Jeff,

I suspect that the reason why propagating negative discharges are sometimes tipped with positive streamers has to do with the way negative discharges propagate via the formation of space stems and space leaders in the space ahead of the main negative leader.

The near end of the isolated space stem/leader (i.e., the gap between it and the main leader) has negative corona within the gap. However, the far end of the space stem/leader has positive burst corona ahead of it. This will becomes intensified if other conductive objects (such as your finger or head) are brought closer to it (thereby increasing the E-field ahead of the streamer tips). The positive burst corona at these far end of the space stems/leaders will thus show heavily branched positive streamer structures.

Hi Chris,I will ask her, if you are on Facebook you can also see her
posts and contact her, she's quite friendly.  The negative streams
are interesting, very hard to isolate in the air....so to study them
in front of your nose you must induce them as surface charges,
normally by placing glass with a sheet of regular paper on top to see
them in the dark.  In the air they show up very occassionally, but
normally are accompanied by positive discharges from the surrounding
air.  Its interesting...the positive dart out as Bert pointed out
into oblivion, trunks 1/2" thick sometimes and visible to 12" or more
(and felt still 16" or more away) yet they never seem to have any
terminations.  The negatives, which form at the brush tips or right
at the ball, are tyically ending ironically (or not?  Bert?) in
positive discharges (they appear in series as it were).  In the case
you see just the negative the moment you approach it a positive forms
at your finger or at the end of the negative...so you  can see them
but not really interact with them.  The positive you can walk into,
play with, as Bert says they as poor conductors (Glad you said that)
because like a cat they sometimes come to you and other times simply
ignore any attempt of interaction.  Put another way sometimes they
bite and other times they ignore you!To show the polarity a simple
device called a Rühmer's Ondoscope or Oscilloscope tube ia used (an
X-Ray gadget, not the wave form CRT).In Tesla's london lecture he
describes phantom streams as perpendicular lines darting out a foot
or more phantomlike into space.  Mostly seen with cylindrical coils,
these straight lines turn into distinct positive forked fractals when
fine tuned...  But are positive always.  The branches sometimes cross
on the same discharge and where they do the color is reinforced
brighter, as if they were layers of colored film.  But an abundance
of positive fractals all with separate trunks can overlap in the air
without a distincion of brightness on crossovers.  Quite curious.
The negative when approached can cause a peculiar ionisation of the
air with bright spots floating around and rod like discharges.  I
have no idea why but its a consistent thing and I havent been able to
measure a clear polarity of them.  The plumes like on Kinraides
booklet "The Jackson Coil" which look like long feathers can be seen
a few inches long in the air, often strangely arcing in curved
patterns along the same plane.  Occasionally a very thin straight
line in the form of an actual spark, not jagged but sharp and curving
shoots out terminating into a negative fan like shape, like a fish
tail or an artists fan brush. Frank Jones and I will be visiting
Kelly in October so probably can capture some of the other events
then...Sent via the Samng GALAXY S® 5, an AT&T 4G LTE smartphone
