Perambulation 6
RM Mentock
Here is an example, today's astronomy picture of the day:
http://antwrp.gsfc.nasa.gov/apod/astropix.html
It depicts a picture of the first quake ever recorded on the Sun.
"Astronomers have only recently figured out when and how to
find them." The quake immediately followed a moderate solar flare.
A link from there is to a page about solar flares:
http://www-solar.dcs.st-and.ac.uk/~alan/sun_course/Introduction/Solar_flares_I.html
which explains that "One major puzzle is to explain how this vast
amount of energy is stored and then released. The only available energy
source is the coronal magnetic field. Thus, the magnetic field needs to
be
stable while excess magnetic energy is stored in it and, then, an
instability is needed to release the energy. Magnetic reconnection is
thought to be the mechanism responsible for converting the
magnetic energy into heat and plasma motion."
A possible source of instability would be meteor, asteroid or comet
impacts. The Sun would be hit many more times than Earth or Jupiter,
and Shoemaker-Levy showed how dramatic such an impact could be.
Interestingly, the first page above discusses the quake wave produced
by the solar flare, and mentions that "The solar ripples are similar
in appearance to waves caused by a rock thrown into a pond." Maybe
they are just like them.
Perhaps there are images already archived that can be studied to test
this hypothesis.

sorry.those waves too simple
leave this ng *now*.
i really mean it.

you are wrong for posting here dude.
you really suck and thru e-mail we all know and believe yuou suck.
we are talking about you behind your back a lot.

the proof is in the pudding. that means you have to beat off a bunch of sperm
into a laundry basket. NOW!!!
try again later.
what's a kill file btw?

when would these events on the sun have happened. I mean how many years
ago. And since we are just seeing them now , maybe the sun isn't even
there anymore but it's going to take many years for us to know.

Between eight and nine minutes, Rab. Half a coffee break, and what
happened at the sun gets here.

Indeed there are. phi...@aol.com posted [1]
to sci.astro on 03 Jun 1998, referencing homepage images
of comets hurtling towards the sun, followed by a large
solar flare [2].
A few hours later, ro...@127.0.0.1 (RB) posted [3]
a copy of a Goddard Space Flight Center note entitled
SOHO SPACECRAFT SEES TWO COMETS PLUNGE INTO SUN
which referenced a NASA site [4] that reported the
two comets were observed on Tuesday 02 Jun 1998.
That page also references a NASA press release page [5]
dated 03 Jun 1998 which adds "In a spectacular coincidence,
a coronal mass ejection (CME) accompanied by an erupting
prominence occurred on the southwest limb of the Sun within
hours after the destruction of the comets. The CME and
prominence were probably unrelated to the comets, being
instead the product of weeks of intense magnetic
activity in that region of the Sun. The eruption of solar
gas was directed away from Earth and does not pose a hazard
to our planet or to orbiting astronauts."
How could we possibly explain the increased activity in that region
*before* the comets hit? For that matter, coronal activity on
the Sun seems to have a decade long period, rising and falling.
Perhaps, there is a belt of material that orbits the Sun, and is
denser in one part of its orbit. As that part nears the Sun,
small particles impact the Sun. The two comets observed by SOHO
might just be a couple of the larger, more visible ones.
