The Quietest Sun

kdawson posted about 6 years ago | from the storms-a-comin' dept.

Space 227

Orbity sends in a Boston Globe report on the unusual calm on the surface of the sun. The photos, many taken in more active solar times, are excellent — see the sequence from last year of a coronal mass ejection carrying away the tail of a comet. "The Sun is now in the quietest phase of its 11-year activity cycle, the solar minimum — in fact, it has been unusually quiet this year — with over 200 days so far with no observed sunspots. The solar wind has also dropped to its lowest levels in 50 years. Scientists are unsure of the significance of this unusual calm..." As if to be contrary, New Scientist mentions that the number of sunspots seem to be increasing.

If there is a mass ejection in our direction it will not matter anyway. Since the new satellites were launched with equipment to monitor the sun from outside our atmosphere, all the really large ejections have been away from us. Give it 10 - 20 years and we should no allot more then we do today.

I should have said know allot...oh well here is some additional information for those seriously interested:

I am by no means an expert, much less an advanced knowledgeable person when it comes to this stuff, I just find it interesting and hope some of you will as well.

I read an article over a year ago about how they could not get good measurements of solar flares because the instruments were not good enough and to get some measurements you needed at least two observation points some distance apart. (probably related to measuring gamma rays) It is my understanding that the earth finally has the right kinds of instruments up there to get very accurate measurements of the sun, solar flares and etc.... I searched around and have provided a few links. I believe you will really like the Youtube video, very cool. Enjoy!

The Solar/SMO [] was planned for 2003 and was finally launched on February 7, 2008. It is designed to measure solar radiation with wavelenghts from 200 nanometers - 100 micrometers. This covers the near-ultraviolet, visible and infrared areas of the spectrum. Here is NASA on Solar / SMO [] .

Hinode [] launched in September 2006 has a three year mission to explore the magnetic fields of the sun. Specifically the investigates the interaction between the Sun's magnetic field and its corona. A consortium including Japan, US, UK and Norway worked together to measure the effects of "magnetic fields thought to be the source of solar flares" Three instruments are used, they are the SOT (Solar Optical Telescope, the X-Ray Telescope (XRT), and the Extreme Ultraviolet Imaging Spectrometer (EIS). The first images were captured on October 28.

HESSI renamed RHESSI [] launched on February 5, 2002, captures solar flares, X-rays and gamma ray flashes. Prior to the launch of RHESSI, we only had the GOES spacecraft which only measured X-ray flux and to classify the size of solar flares. YouTube on HESSI / RHESSI; A solar flare [] video - no sound. Here is a great video [] that shows the various instruments in action, one right after the other. From 10/18/03 through 11/07/03; AR 10486 & AR 10488.

From the Wiki,

The most powerful flare of the last 500 years is believed to have occurred in September 1859: it was seen by British astronomer Richard Carrington and left a trace in Greenland ice in the form of nitrates and beryllium-10, which allow its strength to be measured today (New Scientist, 2005).

Prior to the above launches, the Ulysees was pretty much it for measuring from space, before Ulysses there was only observations from the ground.

Ulysses (17 year mission) [] - was equipped with instruments to characterize fields, particles, and dust, and was powered by a radioisotope thermoelectric generator (RTG). Launched in 10/6/90 through 7/1/08; through "through triangulation (or, more specifically, multilateration). Each spacecraft has a gamma-ray detector, with readouts noted in tiny fractions of a second. By comparing the arrival times of gamma showers with the separations of the spacecraft, a location can be determined, for follow-up with other telescopes. Because gamma rays travel at the speed of light, wide separations are needed." Additional discoveries: Additional discoveries: [15] 1) Ulysses discovered that the Sun's magnetic field interacts with the Solar system in a more complex fashion than previously believed. 2) Ulysses discovered that dust coming into the solar system from deep space was 30 times more abundant than previously expected. 3) In 2007-2008 Ulysses determined that the magnetic field emanating from the sun's poles is much weaker than previously observed.

The current extinction rate is more rapid than in any other extinction event in earth history, and 50% of species could be extinct by the end of this century. While the role of humans is unclear in the longer-term extinction pattern, it is clear that factors such as deforestation, habitat destruction, hunting, the introduction of non-native species, pollution and climate change have reduced biodiversity profoundly.'

Re:Taking pictures of the sun? (1, Informative)

Anonymous Coward | about 6 years ago | (#25365913)

such a welding shield / using welding goggles is also recommended for watching solar eclipses, so I guess you could go with it (oh, an equivalent is a shard of glass smoked over a fire...). preferably aim indirectly, using an LCD screen and a mirror so you don't have to look in the direction of the sun directly; then it will only be a matter of exposure time. even if the welding screen is too strong (those things are incredibly dark, you cannot see through them without a very powerful light source; just don't use one with automatic shielding that only gets dark when there IS such a source, I don't know if it works with direct sunlight alone), a longer exposure time should still get a good picture.
(theoretically with a very short exposure you could also shoot a picture of the sun without any protection... do no try at home?)

Your shutter speed will be maxed so the sensor's exposure to the bright focused sun will be minimal anyway, don't worry about it. Shoot it.

Apart from the other fault pointed out by another poster, you're missing the important fact that not only the imaging sensor is a sensitive component.

The autofocus sensors, the metering sensors, the mirror and *the shutter itself* are all sensitive components. The manual of my Olympus dSLR says not to do it, and I doubt it's in any way unique.

The only responsible advice is to get a filter built for this very purpose before shooting.

Re:Taking pictures of the sun? (4, Informative)

Suddenly_Dead (656421) | about 6 years ago | (#25365955)

The best way to do it is with a solar telescope, which will get you a nice, zoomed-in shot. Alternatively, you can buy solar filters for telescopes, but you must be absolutely positive that they are high quality and you must have one that covers the main telescope aperture; those that cover only the eyepiece are dangerous as fuck.

Re:Taking pictures of the sun? (2, Informative)

ultranova (717540) | about 6 years ago | (#25366079)

Alternatively, you could simply project the image from the telescope to a piece of paper/cardboard and photograph that. That way there's no chance of filter failure, because there is no filter.

Zocalo (252965) | about 6 years ago | (#25366211)

The welder's glass will do at a pinch although it's not really sufficient for prolonged viewing of the sun. You'll also need to figure out some means of fixing it to the camera and you might find that it causes some unusual colour shifts in the image as well. Alternatively, you can get hold of a neutral density filter specifically designed for solar-photography; typically these will equate to about 10-15 stops of light loss - Cokin's NDX is one of the "cheapest" options, but that's relative; these are niche products that can be quite hard to find and are priced accordingly.

As to composing and focusing without damaging the sensor or your eyes... Well, it's a good idea to be quick. :) Assuming you gave a "proper" DSLR with a through the lens viewfinder, then you can use the old trick of holding a piece of card a few inches from the eyepiece for basic composition, and on newer models you can also use the live preview screen function. Be aware though that when using the latter method your sensor will be exposed to the sun, so don't take too long or your sensor may get damaged. Focussing isn't too critical; set the camera to manual focus and focus on infinity before you start, and you should get a perfectly usable result, although for pin sharp shots of sunspots a little more precise focussing may be required. Typically, my approach is as follows:

  1. Set up the camera & lens (manual focus, filter attached, pointed in the right direction, etc.)
  2. Visually look for any sunspots by composing with the piece of card technique then focussing manually to make the image sharp; if there are any then I want to know where they are so I can make sure that they are sharp
  3. Compose the shot
  4. Reset the focus to infinity (it will be slightly off from step #2)
  5. Switch to live view
  6. If there are any sunspots, zoom the live view screen in where they are and focus until sharp
  7. Take the shot
  8. Profit! (hopefully)

Be aware that with longer focal lengths the sun will move fairly rapidly across the viewfinder, but unless you are using an insanely long telephoto lens or a telescope with an adapter then this shouldn't be a major problem if you leave room for the sun to move across the frame when you compose.

Good luck, and don't take any chances with your eyes!

It's even less surprising. If this minimum's activity is lower than the last one, it's automatically "the lowest in the last x!". And if were higher, vice versa.

Indeed, I can't refrain from commenting on the part of TFS that notes that "Scientists are unsure of the significance of this unusual calm..."

I mean, of course they're not sure. They shouldn't care about the significance of what the heavenly bodies are doing at all. That is the area of astrologers and other pseudo scientists.

Any self respecting scientist should answer the question "What does it mean when the sun is unusually quiet?" with "It means that the sun is unusually quiet."

There are electromagnetic cords between the sun and the earth. Our use of electricity is causing a feedback loop that is disrupting the sun. Abandon all hope, technology, and self determination. Go live in a cave. The earth, and the sun, will thank you.

I agree and I was going to make the same observation - no attempt to connect this with global warming? Based on this alone, I'll give you a winter prediction: It's gonna be cold, it's gonna be gray, and it's gonna last you for the rest of your life. :)

This will give us good readings on how the solar cycle affects this climate.

Re:Very convenient (1)

slashname3 (739398) | about 6 years ago | (#25367141)

So when the solar spot cycle is low does that mean there is more or less energy being radiated? It would seem that if there are sun spots that there might be less energy being radiated which would cause the planets to cool. When there are fewer sun spots there is more energy being radiated (more surface area at a constant temperature) so the planets would warm up more.
Do we have any instrumentation that shows the amount of energy the sun is giving off?

Re:Very convenient (1)

locofungus (179280) | about 6 years ago | (#25367533)

It does affect the amount of energy from the Sun but not by much. A bit less than 2W/m^2 between minimum and maximum. [] .

For comparison, the difference between January and July is about 90W/m^2 (with January being higher than July) due to the differing distances of the Earth from the Sun during the year. []

You'll have to ask a climatologist whether a sustained 2W/m^2 change in the solar constant would have a significant effect on global temperature.

It's the aliens that are supposed to be visiting today! They're calming our sun as a token of good will. Clearly, they plan to cozy up, have fun stringing us gullible earthlings along, and then put their sun-calming machines into reverse and roast us alive whilst they laugh.

tjstork (137384) | about 6 years ago | (#25367095)

If the lack of sunspots holds on, then, if we get declining global temperatures, then, we might actually be headed into an ice age. Knowing our luck, this would become evident AFTER we've blown ten trillion dollars to lower our CO2.

MerlTurkin (598333) | about 6 years ago | (#25367137)

The cycle's AVERAGE is 11 years. It could go longer or shorter. This is not a big deal. I believe one past cycle (IIRC) lasted 13 years. Give it a few months. It'll start kicking in.

Wow, I have had 4 Cisco switches reload this year due to "Parity Errors", which they attribute to 'Cosmic Radiation*'. I thought that we were in a high point of solar activity.

* Not sure if solar activity is source of said cosmic radiation.

snspdaarf (1314399) | about 6 years ago | (#25367699)

Yeah, the old "cosmic rays ploy." Back when we used Motorola machines, I had one system that would crash on a parity error. One. Out of five machines, and the only one with that specific type of memory. Also, there were between 12 and 20 other machines in that room that never crashed. The third time the tech came out on a service call he told me the problem was cosmic rays. We dumped the Motorola machines before Y2k, and have not had a cosmic ray problem since.

There is mounting evidence that sunspot activity has an effect on the Earth's temperature. I believe this will be one of the coldest winters in the past 10 years.

This evidence also suggests that Earth is trending towards cooling overall. Not warming like all the 'experts' claim.

Wait and see, this will be one of the coldest winters we've seen in a long time.
