Robotic Solar Observatory, Eyes on the Skies.
Mike Rushford's robotic solar observatory and BBS system
have moved. They are now no longer accessible via the old
dialup line. They are now accessible via the World Wide
Web (http://www.hooked.net/~tvs/eyes/ or the "Eyes on the
Skies " link on our homepage). The telescope can now be
controlled from anywhere in the world over the internet for
free. It's pretty sunny these days, so you can get out there
and do some solar observing without having to get out
there. It is the perfect activity while sitting in front of your
computer at work and looking busy.

http://en.wikipedia.org/wiki/Sun
The Sun is the star at the center of the Solar System. The Sun has a diameter of about
1,392,000 kilometers (865,000 mi) (about 109 Earths), and by itself accounts for about
99.86% of the Solar System's mass; the remainder consists of the planets (including
Earth), asteroids, meteoroids, comets, and dust in orbit.[9] About three-quarters of the Sun's
mass consists of hydrogen, while most of the rest is helium. Less than 2% consists of other
elements, including iron, oxygen, carbon, neon, and others.[10]
The mean distance of the Sun from the Earth is approximately 149.6 million kilometers (1 AU),
though this varies as the Earth moves from perihelion in January to aphelion in July.[20]At this
average distance, light travels from the Sun to Earth in about 8 minutes and 19 seconds.
The energy of this sunlight supports almost all life on Earth by photosynthesis,[21]and drives
Earth's climate and weather. The enormous effect of the Sun on the Earth has been
recognized since pre-historic times, and the Sun has been regarded by some cultures as
a deity. An accurate scientific understanding of the Sun developed slowly, and as recently as
the 19th century prominent scientists had little knowledge of the Sun's physical composition
and source of energy. This understanding is still developing; there are a number of presentday anomalies in the Sun's behavior that remain unexplained.

laser fusion
The principle of nuclear fusion
The energy of every shining star in the universe, including our Sun, is
supplied by nuclear fusion – which is said to be a major energy source in
the future.
When two atomic nuclei are forced into close proximity, nuclear attraction
force overcomes the electrostatic repellent force (Coulomb force), and the
two nuclei fuse into one nucleus. This reaction is called “nuclear fusion.”
http://www.exploratorium.edu/sunspots/index.html
There are many mysteries about sunspots still to be solved. As stellar physicist David Dearborn notes,
"Scientists love mysteries. When you solve something, then it becomes a lot less interesting, and
you go find another question to ask."
Today, scientists use cameras mounted on powerful telescopes to take pictures of the sun's surface
magnified hundreds of times, revealing detail that scientists of Galileo's time would have found
wonderful. But scientists are still trying to find even better ways to study the sun, equipping
telescopes with various filters that capture nonvisible parts of the sun's emission, such as x-rays
and magnetic fields. This section will look at how these new methods for examining the sun are
changing our understanding of sunspots. In addition, this section will explore the sunspot cycle,
and the known and possible effects sunspots have on earth.
What Is a Sunspot?
According to George Fischer, a solar astronomer at the University of California, "A sunspot is a
dark part of the sun's surface that is cooler than the surrounding area, some as large as 50,000
miles in diameter, move across the surface of the sun, contracting and expanding as they go. It
turns out it is cooler because of a strong magnetic field there that inhibits the transport of heat via
convective motion in the sun. The magnetic field is formed below the sun's surface, and extends
out into the sun's corona."

Cosmic Ray Activity at Space Age High
In 2009, the intensities of galactic cosmic rays have
increased 19% over the highest seen in the last 50
years. The main cause is the deep solar minimum which
was first observed around 2007 and continues today.
When solar activity decreases, the Sun's magnetic field
is weakend, and provides less protection against the
charged, high-energy cosmic particles (mainly protons),
so more of them are able to reach the inner solar
system. Cosmic rays can pose a radiation hazard for
astronauts and satellites.

• Warmer surface temperatures also tend to occur during
particularly active parts of the solar cycle, known as solar
maximums, while slightly cooler temperatures occur
during lulls in activity, called minimums.
• A deep solar minimum has made sunspots a rarity in the
last few years. Such lulls in solar activity, which can
cause the total amount of energy given off by the Sun to
decrease by about a tenth of a percent, typically spur
surface temperature to dip slightly. Overall, solar
minimums and maximums are thought to produce no
more than 0.1°C (0.18°F) of cooling or warming.
• "In 2009, it was clear that even the deepest solar
minimum in the period of satellite data hasn't stopped
global warming from continuing," said Hansen.

The last renewable resource to consider is solar energy. The solar constant is
1.76x105 TW, hence, there is ample solar energy potential. Solar energy is, in fact,
the
only renewable resource that has enough terrestrial energy potential to satisfy a 1020 TW carbon-free supply constraint in 2050. From the 1.2x105 TW of solar energy
that strikes the earth’s surface, a practical siting-constrained terrestrial global solar
power
potential value is about 600 TW. The numbers range from very conservative
estimates of
50 TW to optimistic estimates of 1500 TW, depending on the land fraction devoted to
power generation. A good number to use for onshore power generation potential is
probably 600 TW. Thus, for a 10% efficient solar farm, at least 60 TW of power could
be supplied from terrestrial solar energy resources. For calibration,
photosynthesis
• currently supplies 90 TW globally to make the biosphere run,
so the amount of power
• available from the sun is very large number by any measure.

During photosynthesis, plants use sunlight to break water into hydrogen and
oxygen atoms and later on the atoms recombine and produce energy. MIT
scientists have tried to duplicate this method of plants to store sun’s energy.
The main constituent in Nocera and Kanan’s procedure is a new catalyst that
generates oxygen gas from water and another catalyst produces hydrogen
gas. The catalysts are cobalt and platinum.

Getting information over the internet may be much cheaper than (say) physically driving to a library and getting a book that had to be
transported there, but there still is a cost. In order to identify ways to reduce energy consumption, it is important to understand what the
energy cost of our actions is.
•
•
Hosting cost is thus: 2e-5 X 12 Watts X 24 hrs/day /500 hits per day = 1.152e-5 kWh per hit
the variable energy required per 25000 bits over the last mile is:
25000 bits X 1.05 X 4e-10 sec X 10 mW (opt) X 3.22 mW/mW = 3.381e-04 Joules = 9.392e-11 kWh
•
Fixed "cost assumption: Point of presence (POP) unit consuming 200W, feeding 24 subscribers (no ref yet)==> consumes 0.2 kWh per
subscriber per day. This must be amortized over total daily consumption. Assuming one page download represents 0.1% of total daily
usage, this represents 0.1 kWh X 0.1% = 1.00e-04 kWh for POP electronic equipment cost
•
Last mile cost for transmission of one page is thus the sum of the two, or approx 1.00e-04 kWh
•
•
•
•
http://michaelbluejay.com/electricity/cost.html
• 100 watts x 24 hours/day x 30.5 days/month = 73,200 Total Watt-hours/month
• 73,200 Wh/month / 1000 = 73 kWh/month
• 73 kWh/month x 15¢/kWh = $11/month.; $132/yr.

How to track sun not chart?
Fred and Leonard
In the attached image you can see the sun and stars
behind it, using the program at this link;
http://www.ap-i.net/skychart/en/download
So I am wondering if the real sun could be blocked dimmer
to to enable us to see some stars near the sun limb.
What I am wondering is how dark is the sun image when
viewed on the Sodium line center?
If solar image intensity could be dropped many order of
magnitude there might be some stars, FAR away so that
the sodium line center is shifted red of the solar absorption
line center, thus if such is the case for a select few stars
might we see them in a SHS?
Thoughts or know if anyone has given this some thought
already know of a paper?

Razdow Telescope
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Razdow Laboratories, Inc. was founded by Austrian born physicist Dr.
Adolph Razdow (1908 - 1985). A refugee of the Holocaust, he emigrated to
the United States in July of 1946. In the early 1960s Razdow was awarded
a contract by NASA to develop and deploy a series of solar monitoring
telescopes at major observatories around the globe. These devices
automatically tracked the sun across the sky, recording and transmitting
television images of the solar disk in the Hydrogen-alpha spectrum. NASA
Astronauts, which would soon be traversing the space around the earth
would be vulnerable to radiation storms caused by solar flares, and these
telescopes were commissioned to provide a 24 hour watch on solar activity.
A few of these telescopes are still in operation.[1]

Solar Physics 10 (1969) 502-510; 9 D. Reidel Publishing Company,
Dordrecht- Holland
The optical telescopes (Figure 3) have 110 mm objectives with focal lengths of
1876 mm. The hydrogen-alpha line is selected by a birefringent Lyot-type filter
with a 0.5 A passband. During Apollo missions, the telescopes are manned by
visual observers; for routine patrol, the data are recorded on 35 mm fihn every
10 sec from approximately 1 hr after sunrise to approximately 1 hr before
sunset. Each telescope is equipped with a video camera which provides a realtime display. In addition, an
eyepiece camera is provided for recording interesting activity for immediate
processing
and inspection.
Two observatories, located at
Boulder, Colorado, U.S.A., and Culgoora, Australia, are operated for NASA by
the Environmental Sciences Services Administration (ESSA). The other two observatories,
located at Teheran, Iran, and Oahu, Hawaii, U.S.A., are operated for
NASA by the Air Weather Service of the U.S. Air Force. Except for the Teheran and
Hawaii stations, all the observatories have been in operation throughout 1968; results of the optical
flare patrol are routinely reported in the ESSA Solar Geophysical
Data publication. During 1968, SPAN detected about 70 percent of the total international
list of flares, as published in this report. The addition of the Teheran and
Hawaii observatories is expected to increase the percentage of flares detected by
SpAN to about 90 percent. The coverage of the seven SPAN observatories is shown
in Figure 1.

Dear Mike, The images you provided are of the RAZDOW solar telescope. These instruments
were originally purchased by NASA and provided to NOAA in the 1960's. Boulder's RAZADOW
was installed in 1967. A little history, watching the sun in the 1960’s was the job of the
SDL/ITSA Space Disturbance Forecast Center (today it is the forecast center of the NOAA
Space Weather Prediction Center) in Boulder, Colorado. The SDFC was tasked to provide daily
solar geophysical forecasts, warnings and alerts of solar activity. This was also the early days
of NASA and ESSA implementing the first stages of solar proton warning systems to alert on
onset of potentially hazardous solar particles (which would become direct space environment
support for Apollo missions around 1971). To accomplish this task the SDFC started 24-hour/7day operations in 1966 and staffed the center with forecasters, observers, and communication
operators. By 1968 a Global Solar Particle Alert Network (SPAN) was established (using the
RAZDOW solar telescope) composed of SPAN, U.S. Air Force Air Weather Service, national
and international observatories to aid in this endeavor. The RAZDOW company went out of
business in the late 1980's. Some of these telescopes were later loaned out to various
research institutions for use in monitoring solar activity. One of the last loan agreements I could
find was with the Lockheed Missiles and Space Company, INC. Research and Development
Division signed by a W.J. Jaynes, Contract Administration dated 22 April 1994. I hope this
helps. If I can be of further assistance please let me know.

We really would like to do these kind of videos regularly at Chabot as the interest in the Sun is definitely growing
with the public. WE have lines on Sunday for the Sunspotter, the Coronado-70, and the Fraunhofer
spectroscope. The visitors all ask about how the sun's surface is changing in time. Some go see a show and
come back in an hour or two and exclaim that the shapes of the prominences have changed a lot. Also lots of
discussion about the sun using Ben's great spiral books of graphics. We also do the gas discharge tube spectral
lines with the grating glasses and everybody loves that experience too.
•
Wow, I sure wish Chabot would proceed with the LaPalma Vacuum Solar Telescope installation while we still have
the Meas. G money left. This would be such a huge draw. Can you just imagine what a 20" refractor with a 78 ft
prime focus can do?
•
Next time, Jim, you are up at Chabot, let's go look at all the refractors we have and some equatorial mounted long
focal Cass reflectors to see if any can work with the Lunt filter. Chabot has a video camera.

20 years, even 10 years ago, viewing the sun in this manner seemed out of reach because of the expense of Ha equipment. It’s still not cheap, but at
least now we mere mortals can at least get a foot in the door.
I do need to point out that the video camera makes all the difference in observing with the 50mm filter. The view through the eyepiece is interesting at
low magnification, but difficult at higher magnification because the image dims considerably. The more sensitive video camera, on the other hand,
allows far better views and can capture fine structure not easily visible or totally invisible in the eyepiece. Video also provides an efficient means of
comparing chromospheric features on and off the Ha line, since most feature variations tend to be subtle.
My main intent going into Ha solar is to produce time lapse videos of prominences. Active prom action over the weekend was nill, but I shot about 25
minutes of video at 1 minute intervals and am now working out the processing, combining and mode of presentation – probably an animated GIF for
starters.
Having some kind of good time now.

http://weeklyrot.wordpress.com/2008/08/
lightning strikes are rare; power outages and brownouts are common
Internet connectivity slow and fails, so go out take a look
around in the observatory.
See ants on the wall warts running internet parts.
Left Obs door open, return home get camera return find
fewer ants take picture.
Close door return home get bug spray, apply on problem
and around outside observatory. Go out for dinner 2hr.
Research on internet after dinner web working fine, discover
ants that eat electronics in Tx at above link they say the
following:
“
The ants can’t actually eat the wires inside electronics. Only
leafcutter ants can do that, and they don’t care for
electronics. Instead, the Crazy Rasberry ants chew on the
softer insulation around the wires, causing electrical shorts.
The live wire then electrocutes the ant. It releases a chemical
alarm pheromone that attracts its nestmates, who further
attack the wires. The buildup of dead worker ants continue to
hinder the electronics.
