Aurorae and Meteors?

“Even though there's no 'storm' predicted, the Leonids meteor shower peaks on Monday night the 17th. Unfortunately the radiant rises around midnight with the Moon (~40% full) rising about 1 am. Not too much of a 'window' there, but what the heck.

Also, the sunspots that caused all the previous excitement will be coming around to face Earth again in a few days, so more Northern Lights could appear.

2003 Leonids FLASH No.1 (02:00UT 12th Updated)

http://homepage2.nifty.com/~baron/leo03p.htm

-----------------------------------------------------------

This flash announcement is provided by The International Project
for Radio Meteor Observation. I show the first announcement of
2003 Leonids. A current Leonid activity is usual activity. We
do not catch an unusual activity yet. On the other hand,
Japanese observing station using 28MHz radio wave is catching a
small increase of the number of meteor echoes. I am receiving
many worldwide data now. I therefore will update announement
later.

You can see this FLASH result and LIVE Radio data. LIVE is
updated every 10minutes at almost of stations.

“Thank you.”

“Thanks for the update Tilt. I have an auto update and It posts every day sometimes more that once a day. Should be a good show at Mount Rogers!”

“Sweet! Thanks for the heads up.”

“Yaz... It sounds like it might be a little nippy up at Mt. Rogers. You guys better keep your extremities under wraps, <G>”

“I look forward to this every November!”

“I usually take the Weasel car camping...

She's a tremendous meteor fiend. Just can't get enough of 'em. Her first trip was the Leonid Storm and now she's spoiled rotten.”

“That darn radiant!

Why does it always have to rise?”

“Oooooooooh...

Here's a killer-diller new Leonid website. There look to be some nifty animations of the different Leonid streams. The numeric designations refer to the years of the different passages of the precursor comet Temple-Tuttle.

We cross Stream 1533 Tuesday night... 2:30 am eastern, 1:30 central, etc. Folks in the Western timezones seem to be in the best shape for this one.... because th' Frickin' Moon rises just before 1 am (40% full), <GRRRRRrrrrrr>.

Hourly rates could be as high as 120, but the predictions aren't firm at all.”

“ERRRrrrr, make that "as high as 100... but predictions (yadda-yadda)."”

“And of course, David Asher's website at the Armagh Observatory.

Great stuff there.”

“

ALRIGHT SLACKERS...

Nearly everyone east of the Missisippi is screwed by the weather; you guys out West ought to at least stick your heads out of the window and see One Meteor tonight....

<GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR>”

“Yo Tilt

Did you see the NOVA program on PBS lastnight about the Earth's Core and Magnetic field?”

“Crap! I saw the commercial for it then forgot all about it!

So... is the planet going to 'swap ends' or what?”

LEONIDS 2003, VISUAL


The 2003 Leonid meteor shower has not yet provided distinct
peaks of activity. A full week of moderate Leonid meteor
rates has shown only one clear maximum; near 2003 Nov 19.4 UT
with an uncertainty of roughly +-6 hours.

This maximum coincides with the predicted times of about
06h30 - 08h00 UT for the encounter with the 15-revolution
dust trail of parent comet 55P/Tempel-Tuttle. The dust
was ejected from the comet near its perihelion passagein
1533.

The material ejected in 1499 has produced enhanced rates
on November 13, but no clear peak time can be derived from
the data received so far.

The ZHR gives the number of meteors as if the radiant would
be in the zenith, and at an observer's stellar limiting
magnitude of +6.5. The latter condition implies strong
extrapolations of observed meteor numbers, since the waning
moon interfered with most of the observing periods.

At this preliminary state, only the relative variations in
the ZHR should be of interest. Absolute values must be
discussed and fixed with the full dataset.

“I think they have a lot of stuff online about it.... We are pretty close to another swap but not in our lifetimes.

Northern Lights would migrate to points all over the world due to a reduction in the sheilding of solar winds over populated regions....”

“That might be a little TOOexciting, <G>. Could be tough on the electronics.

I need to check out the PBS site. Sometimes they replay NOVA on South Carolina Public TV later in the week (one of the many benefits of living on the GA-SC border...).

Looks like some folks Did just miss having the Aurora/Meteor Combo...


Space Weather News for Nov. 20, 2003
http://spaceweather.com

A coronal mass ejection swept past Earth during the early hours of Nov.
20th and sparked bright auroras over northern parts of the United States.
At the time of this writing (1600 UT or 11:00 a.m. EST) a strong
geomagnetic storm is in progress. The interplanetary magnetic field near
Earth has tilted sharply south--a condition which promotes geomagnetic
activity. If this condition persists, auroras are possible at low
latitudes tonight.

The source of this space weather is sunspot 484--one of the trio of big
sunspots that caused intense solar storms last month. Indeed all three of
those active regions are back on the Earth-facing side of the sun, so more
solar activity is possible in the days ahead.

Visit Spaceweather.com for more information and pictures of today's
auroras.”
