Some knucklehead made a hate post on one of my recent threads and it
seems that perhaps the entire thread may have been cancelled from
google groups. Why should anyone expend time and energy posting if
they can't be read?

Anyway, somebody might have noticed that over the years I've gone from
posting an average of a SETI news story a day to rarely posting them at
all (the news stories are still out there if somebody wants to look, I
just haven't had the time because of family and business-related
pressures.) If only I could make money from reporting SETI news (but
the audience seems so small that perhaps that business would be
bankrupt in a short while? I wish I could give it a go though, in the
form of a magazine or newsletter, maybe someday.) I also have ideas of
doing amateur SETI science; one I'm working on now takes an optical
SETI approach similar to the comparitive photometry used in transit
searches (in the free minutes that I get every month). I have a
tentative approval to use the observatory on weekends. I HAVE
IDEAS!!!!! (If only I had the luxury of time and money to execute
them.)

I just want to say thanks the most to Alfred A. Aburto Jr. (I hope you
achieve your goals!!!!), Joseph Lazio (thanks for steering sci.astro
too!), Peter Backus (for taking the time from your busy schedule and
enriching this NG and to all of the other SETI Institute scientists who
generated the news stories over the years), THE ERIC's at ***@home and
the other excellent leaders at ***@home who spared the time to
respond to inquiries awhile back even though they faced a task
un-imaginable to most people, even me :^), Jonathan Silverlight,

It has been a pleasure corresponding with you over quite a few years
now. I hope you post something now and then. Please do!

I know we have talked in the past about tracking/monitoring Saturn and
the other planets for EM emissions. I think this is a good idea, but one
needs a fairly good size radio telescope for that and the ability of the
telescope to track the planets across the sky. This is difficult for a
rank amateur like me.

However as an alternative I have been reading up on celestial mechanics
and I think I understand now how to implement simple (known) algorithms
to track (determine RA & DEC for) the Sun, Moon, and planets (except
probably Pluto) for any date. Then with this information and the
***@home data base that I have (about 130000 WU results) one can see if
there is an extraordinary number of SAH spike/guassian RA&DEC positions
("hits") that match up with the Sun, Moon, and planet positions for all
the given dates (of spike & gaussian hits). With the Sun I'd expect to
see a slight increase in hits perhaps because the Sun is a source of EM
radiation. With the Moon I'd expect to see a decrease in hits perhaps
because the Moon is not a source (except by reflection from Earth!) but
would block true extraterrestrial sources. Well, this would be a good
(fun) thing to test. In fact ***@home should do this themselves with
all the millions of spike and gaussian hits they have in their database!
Anyway, I'm going to check my own database paltry as it is and see what
I find. I'll let you know (I don't expect anything, but ...)

Best regards! I'll keep looking too, but after SAH classic stops I'm
probably going to take a break (after over 6 years of crunching).

Have you checked with the Bracewell Radio Astronomy Site Project?

http://www.bambi.net/stanford_dishes/rescue.html

Having a real project getting at least one dish operating would
be proof to Stanford that the side is useful and can contribute
to science.

I don't suppose you're near the site?

Gary,
I'm a supporter of the project via SARA. I didn't think of using the
site though :-( ... I'm in San Diego and the Stanford "dishes" aren't
all that close, but maybe I'll put a plan/proposal together. I could use
the USRP (http://www.ettus.com/) radio tuned to 1420MHz, or other band.
I think the USRP can tune 30MHz bands. It would be a good start at
least. (the 1420MHz radio isn't completed yet ... it is not listed on
the site ...)

Include a bit of automation to allow remote operation and you'll be
all set. Stanford could also use it for a remote security monitor link.

Any idea what is necessary to get it finished? I wasn't able to find
an address to mail donations to on the Bracewell site, or any list of
what equipment might be needed.

I'll send you his address. It is going to take some $50K/year or so to
keep the telescopes operating (maintain the facility). I think it is
going to be tough to do from just donations, but perhaps it will work
... a group in Georgia maintains two 100 ft dishes ...

I'm waiting for the next update ... don't know about specific equipment
needs ...

I agreed with my family that I'd take out all those computers I have
working away 24/7 at various corners of the house (end of April, now May
to mid-June, 2005). Those machines use quite a bit of electrical power
too (about $50 or so extra a month for 6 machines). I might do one
computer with BOINC SAH later but that is it.

I like crunching data, but more, I like looking at and analyzing data
myself most of all (its in the blood I guess!) ... I'd have to start
over fresh with BOINC (collecting data files) and I'm not real
enthusiastic about that right now ... maybe in the winter I'll regroup
and run one machine with BOINC SAH ...

especially when you do find something unexpected or if you can
conclusively prove or disprove whatever theory. Let us know what you find!

Both the sun and the moon are sources of thermal radiation. However,
any source of pure thermal radiation will generate the same hit
rate in ***@H (about 1 or 2 per work unit per detection mode). That
applies to any source of random, broadband, noise.

EME stuff would fizzle out way below the water hole frequencies.
EME is, effectively, sent *IN* the waterhole (1296MHz), for obvious
reasons. In fact, there is an EME beacon operated by the SETI League
for testing SETI sensitivity, which has been used by project Phoenix.
It's also done in the 145MHz region. The 23cm signal shouldn't have
too many harmonics in the ***@H coverage range, although spurii from the
multiplier chain or mixers may be there.

Did you really mean in the immediate vicinity of the hydrogen line.
Post by Martin 53N 1W
But it is also a reminder that you might find some surprises...
Once you clear the protected radio astronomy frequencies, I believe that
you will get quite a bit of leakage reflected back.

As, as Arecibo's beam is narrower than the angle the moon subtends,
you will see the full thermal noise, which will degrade the signal to
noise ratio, although the ***@H data does not include the absolute power
level of the signal and you would still get the same number of false hits
(around or or two per type per work unit).

I was thinking more that any EME and harmonics would actually be way
away from the protected part of the spectrum (hydrogen line), leaving
just anomalies to be picked up if someone is transmitting with very bad
IF stages or otherwise overdriving... (:-P)

From my understanding: Our moon radiates EM due to its temperature. The
***@h threshold (that magic 22) will on average pick up one or two hits
just from the random thermal noise that Arecibo is looking at when
viewing the moon.

The Earth RFI and EME RFI come as extras.

What I'm interested in investigating are SAH "hits" (spikes & gaussians)
not from the Moon. The SAH classic database contains billions of spike
hits for example. Each square 0.5 degree square of the sky (about the
spatial area covered by the Moon) contains hundreds or even thousands of
"spike" SAH hits depending upon the total number of data samples
utilized. I was hoping to see the total number of hits change for those
times and areas occupied by the Moon compared to the median number of
hits with no Moon. The number of hits from the Moons radiated thermal
signature would be minimal I was thinking compared to the average number
of hits per sqaure 1/2 degree in the database. It could be a problem I
suppose but I would find that out. If it was a problem then I could
select times near New Moon for example (it might be good to do this
check anyway: check number of hits versus phase of the Moon for example
but the more refined one gets the more and more data is required).

The RFI from Earth however could overwhelm everything. I'm hoping most
of the spikes are external to the Earth & Moon though ... We'll see ...

The Earth RFI and EME RFI come as extras.

Some /real/ research!

Go for it, and good luck.

Hi there,

I am trying to track down Jason H's contact details regarding one of his photographs on Flickr - I work for an astronomy TV show and we're interested in using the image in one of our episodes.

If anybody knows how to get in touch with Jason, please can you drop me a message with the details.

Many thanks,

Victoria

Some knucklehead made a hate post on one of my recent threads and it
seems that perhaps the entire thread may have been cancelled from
google groups. Why should anyone expend time and energy posting if
they can't be read?
Anyway, somebody might have noticed that over the years I've gone from
posting an average of a SETI news story a day to rarely posting them at
all (the news stories are still out there if somebody wants to look, I
just haven't had the time because of family and business-related
pressures.) If only I could make money from reporting SETI news (but
the audience seems so small that perhaps that business would be
bankrupt in a short while? I wish I could give it a go though, in the
form of a magazine or newsletter, maybe someday.) I also have ideas of
doing amateur SETI science; one I'm working on now takes an optical
SETI approach similar to the comparitive photometry used in transit
searches (in the free minutes that I get every month). I have a
tentative approval to use the observatory on weekends. I HAVE
IDEAS!!!!! (If only I had the luxury of time and money to execute
them.)
I just want to say thanks the most to Alfred A. Aburto Jr. (I hope you
achieve your goals!!!!), Joseph Lazio (thanks for steering sci.astro
too!), Peter Backus (for taking the time from your busy schedule and
enriching this NG and to all of the other SETI Institute scientists who
respond to inquiries awhile back even though they faced a task
un-imaginable to most people, even me :^), Jonathan Silverlight,
Klaatu, Rob Dekker, SETI ITALIA Bruno IK2WQA, Anthony Cerrato, Martin
53N 1W, Martin G. Diehl, red, Alfred Das (RIP),Rich, David Woolley,
Paul Bramscher, FalconFly, Gary Heston (and all the other Gary's too!
:^), Robi, Eric, Carolyn Cehlen, Rashid Faizullin, Russell Wallace,
Martha Adams, Roy Bamford, Yvan Dutil, Erich Habich, Terry Groff, Jay
C. Parangalan (are you still lurking? Thanks for that signal processing
software suggestion, I'm still using it and may use it even more now),
smcx1, Brad Guth (and your Venus :^), Matt G1w&r, the doubtless dozens
of others that I can't remember right now and those who must remain
anonymous for professional reasons but who sent me e-mails over the
years (all I can say to others is watch for their coming scientific
papers, they are the only way we can move forward.)
KEEP SEARCHING!!!!!!!!!!!!!!!!!!!! I am.
Jason H. (lurk mode on.)
How's your latest grasp of physics, astrobiology and deductively interpreting the best available science?
