I think, Mr. Marsden (and I also) don't make an error during calculation
the positions. I found the comet also on the position. So the ephemrides
of Scott Smith are simply wrong or the equinox is wrong...

Sorry to even bring this up, but I go to a private college that is fairly 
conservative religously.  I was arguing with this kid about the age of the 
earth, saying that it was at least 4 billion years old, and he pulled this moon
dust theory on me that there would be more dust than we found if the moon were
as old as we think.  

I have heard of this before, but can anyone tell me the reason this theory was
shot down?  I need to throw some reality back in his face.

Thanks.

 For Eric Goldstein and sci.astro from Woody Sullivan:
 
   A colleague forwarded to me your comments on sci.astro. and here is my
response.
 
 Radio leakage from another planet circling another star that is similar in
nature to the earth's can indeed be picked up by the Targeted Search portion
of the NASA High Resolution Microwave Survey (HRMS) program. See Science,
Vol. 199, p. 377 (1978) for all of the details and
Vol. 202, p. 376 for a short
follow-up. A US Navy surveillance antenna in Texas provides the greatest
effective radiated power (ERP) of any steadily transmitting earth source that
beams into a reasonably large fraction of the sky each day (in other words,
excluding the much more powerful Arecibo radar, which with its very small beam
and infrequent schedule is not likely to illuminate any particular sky
position that one is interested in). Its ERP is 1.4E10 W into a band as narrow
as 0.1 Hz at 217 MHz and a beam about 120 deg by 1.5 arcmin. At Alpha Centauri,
this produces a flux density of 700 Jy. The HRMS will be concentrating on the
1-10 GHz range, so it would not pick up this transmitter, or the BMEWS radars
or the television video carriers. The sensitivity of the Targeted Search (for
nearby solar-like stars), however, is about 140 Jy for a signal of
width 1 Hz and thus could definitely pick up this type of signal. Right now,
our most powerful transmitters are at frequencies below 1 GHz, but technology
is pushing things to higher and higher frequencies, so it is not all
unreasonable to expect strong leakage from other civilizations at > 1 GHz.

The "face" is located in the Cydonia region of mars.  I don't have the
coordinates with me but can get them easily if anyone is interested.
There are two pictures of the region; 35A72 is taken with the sun at
10 degrees above the horizon and 70A13 with the sun at about 27 degrees.
Both images are full of spike noise, probably the result of toggled bits
during the transmission of the data.  Also, both are very dim although
some contrast enhancement will work wonders.

Hopefully we'll get some hi-res shots.  Of course, if it's not there
some people will accuse NASA of a coverup.  sigh.

This is of course true, but building a rigid Dyson sphere has enough other
problems that a little transmutation (just fuse all the hydrogen and helium to
carbon and oxygen - as a bonus you get some energy to help with the construction
work) seems minor.

All Dyson really observed was that a really advanced civilization might be
expected to be using  (somehow) all the energy of their star, and re-radiating it
as waste heat (necessarily from a larger surface) and that it might be worth
looking for 'stars' that were big and cool in this way.

I had trouble sleeping last night and so I trotted out to my 20" around
2:00 a.m to do further research on the MOON, MARS, and other likely
places to find evidence of INTELLIGENT life in the universe.

I was UNDOUBTABLY compelled to due this because of the major EARTHQUAKE in
CAIRO. I have noticed that whenever there are major earthquakes, I have
either seen the Moon or the SUN or both shortly before or after the
earthquake. I take it that this is because of low frequency ELECTROMAGNETIC
waves impinging upon my GRAY (GREY?) MATTER.

I quickly had my EQUIPMENT operating and had the MOON in view in a 9mm
NAGLER giving 282x. Knowing that detail is best seen near the TERMINATOR
(because of fear of death if I do not pay attention) I concentrated my
search along it. I also use a 6 foot (183 CENTIMETER) step ladder to
HEIGHTEN the effect. I swept my scope along it.

My eyes were riveted by a sight I have not noticed before. I finally had
been found WORTHY by the great SPACEGOING races. There about midway was
a huge FOOTPRINT. This footprint must be 100 miles by 30 miles in size.
The imprint of the heal and toes was so OBVIOUS. That fact that I have
never seen this feature attributed to ALIENS going only be due to a
coverup of ALL ASTRONOMERS, PHYSICISTS, and every possessing more than
a SECRET clearance for the goverment of the U.S.A. and other
TECHNILOGICALLY sophisticated countries.

And I thought we had BIGFOOT here in the NORTHWESTERN U.S.A. A number of
possible explanations for this feature come to mind.

1) The same race that left us ELVIS on MARS also sculpted his FOOT on the
moon for those with an OPEN enough mind to see it.

2) The great SPACE PATATO felt the need to be turned into FRENCH FRIES
and so arranged for an ALIEN big enough to eat it to have a PICNIC on
our SATELLITE. Of course it goes without saying that a RADIATION
PERIPHERY was used to cook the PATATO.

3) An huge ALIEN race has made the moon a TEMPORARY base as they prepare
to move VENUS into EARTHS much friendly orbit. We know that the knew
orbit will not be stable but VENUS is the goddess of LOVE and certainly
if VENUS kisses the earth once or twice it shouldn't really matter.

After this major accomplishment of detected ALIEN life before HRMS I
am sure that the U.S. Government will be proud to award me the 20$ million
that HRMS is budgeted. I will of course spend that money on better equipment.
WHO KNOW what I could accomplish with a 4.8mm NAGLER.

I then turned my TELESCOPE on MARS but was dissappointed that I was not
able to see ELVIS. Perhaps it is time I move to KALAMAZOO and start
frequenting SUPERMARKETS.

I would like to point out that my training is in PHYSICS and that I am
certainly willing to subject my findings to the kind of REVIEW that they
deserve. I am also willing to sell my exclusive story to the highest
BIDDER. (Did I tell you about the time I used my Telescope to see
Clinton with a BABE ...

There is no question that it is NOT the planetary nebula green line. On  
the other hand bright green meteors are relatively rare in my experience  
so why would one line sometimes dominate so much? Would the composition of  
the body itself not be important - if some brightly fluorescing ion made  
it from the object to the fireball it could dominate, similar to those  
Yule logs impregnated with chemicals - a small amount of copper salts can  
completely change the color of the flame. By the way 5577 is the auroral  
oxygen green line and is also forbidden so that is not the line  
responsible.

There are occasional questions on the net about amateur radio astronomy.

I thought I'd put this information sheet together, hoping to help out
a few wanna-be's.

The following are the only ones I'm aware of.  I was a past member,
and used to subscribe to both journals.

I personally own a 12 foot and a 20 foot dish, spectrum analyzer, and
necessary front-end electronics to get on the air, but have disassembled
everything because of moving.

If you have any further questions, I'll _try_ to answer them.

     Venus is quite easy to observe in daylight, even with naked 
     eye.  The only problem is to find the object and it is not
     so easy, because to eye will not be focused to far due to
     the light sky.

     The first step to observing is to check numeric data:

	- Elongation of Venus
	- RA & decl of the Sun and Venus
          --> azimuths and altitude

     When observing with naked eye and binoculars, just check
     the difference of azimuth and elevation and search there.

     When using fixed parallatic mounted telescope you can
     set the declination value to the value of Venus, then find 
     the Sun (be careful, don't look throw the telescope!) and
     then just turn telescope to the direction of Venus.  With
     elongation value you can estimate how much you should do
     that.  I think Venus is observable already with your finder
     scope.

Excess launch capacity, drinking buddies who liked to "double-dare" him

No-one seems to have focussed on what makes a fireball bright green. I saw  
a bright green fireball several months ago...the first of this color I  
have seen among thousands of meteors I have seen. The green was very  
startling, but what makes it. It is NOT the auroral green line. What IS  
it?
