SOLAR WATCH * Huge X8.2 Flare Sept. 10, 2017! (Updated Daily) | |
Isis One User ID: 14343270 United States 08/15/2013 11:00 PM Report Abusive Post Report Copyright Violation | Voyager 1 has left the solar system, says new study Quoting: AKObserver 2 hours ago (Phys.org) —Voyager 1 appears to have at long last left our solar system and entered interstellar space, says a University of Maryland-led team of researchers. Carrying Earthly greetings on a gold plated phonograph record and still-operational scientific instruments – including the Low Energy Charged Particle detector designed, built and overseen, in part, by UMD's Space Physics Group – NASA's Voyager 1 has traveled farther from Earth than any other human-made object. And now, these researchers say, it has begun the first exploration of our galaxy beyond the Sun's influence. "It's a somewhat controversial view, but we think Voyager has finally left the Solar System, and is truly beginning its travels through the Milky Way," says UMD research scientist Marc Swisdak, lead author of a new paper published online this week in The Astrophysical Journal Letters. Swisdak and fellow plasma physicists James F. Drake, also of the University of Maryland, and Merav Opher of Boston University have constructed a model of the outer edge of the Solar System that fits recent observations, both expected and unexpected. Their model indicates Voyager 1 actually entered interstellar space a little more than a year ago, a finding directly counter to recent papers by NASA and other scientists suggesting the spacecraft was still in a fuzzily-defined transition zone between the Sun's sphere of influence and the rest of the galaxy. But why the controversy? At issue is what the boundary-crossing should look like to Earth-bound observers 11 billion miles (18 billion kilometers) away. The Sun's envelope, known as the heliosphere, is relatively well-understood as the region of space dominated by the magnetic field and charged particles emanating from our star. The heliopause transition zone is both of unknown structure and location. According to conventional wisdom, we'll know we've passed through this mysterious boundary when we stop seeing solar particles and start seeing galactic particles, and we also detect a change in the prevailing direction of the local magnetic field.

I dont believe much from NASA, how has voyager got through the asteroid belt?, The magnetic fields must be very weak that far out surely, how do they know it is not faulty data. anyway with our suns field still changing could that be the reason they are so confused. How do they know when it has officially left the "solar system", is there a big box or line or roadsign it passes thru? magnetic fields are propagated in flux lines which are waves right? so they will be diminishing with distance but will propagate forever making definitive classification of what is, and what is not our solar system difficult, surely. I don't understand the significance anyhow, what does it matter. |

Hugh M Eye User ID: 39479530 United States 08/16/2013 12:09 PM Report Abusive Post Report Copyright Violation | Yes, things can change rapidly with the sun. For example, check out this story from late 2003 (2 years after solar max): THE SUN GOES HAYWIRE! (NASA Press Release) Then, suddenly, in late October the sun began to behave strangely. Three giant sunspots appeared, each one larger than the planet Jupiter. In California where smoke from wildfires dimmed the sun enough to look straight at it, casual sky watchers were startled by the huge blotches on the sun. One of them, named "sunspot 486," was the biggest in 13 years. (snip) Sunspots cause solar flares and, usually, the biggest flares come from the biggest spots. The three giant sunspots unleashed eleven X-class flares in only fourteen days--equaling the total number observed during the previous twelve months. "This was a big surprise," says Hathaway. All this happened two years after solar maximum, which raises a question: is something wrong with the solar cycle? Is the sun going haywire? "Nothing's wrong," reassures Hathaway. The sun isn't about to explode, nor is the sunspot cycle broken. "These latest sunspots were whoppers," he allows, "but sunspot counts averaged over many weeks are still declining as predicted. We're still on course for a solar minimum in 2006." Indeed, it's possible that what we've just experienced is a normal part of the solar cycle, speculates Hathaway. "There's a curious tendency for the biggest flares to occur after solar maximum--on the downslope toward solar minimum. [link to science1.nasa.gov] Among those 11 X-flares was the legendary record-shattering X28 flare. |

[link to lasp.colorado.edu] Quoting: muse_1111 It is showing a spike today and states "Warning: Dark 43.1" Thanks in advance! This has come up before but I forgot the answer, muse1111. A little pain-staking research has given me a clearer idea, although a plain old explanation is hard to find. I'm not a huge techie, so excuse me if this in error. The Dark Count is a sensor-calibration measurement of current (ie,voltage) and resulting thermal properties. The EVE instrument measures solar irradiance in multiple wavelengths in fine detail and has many filters and such. The dark count must be compensated for so as not to degrade the data being recorded. Here is one definition I found from Apogee Imaging which makes CCD imagers for some NASA projects- Dark Count Next to the quantum efficiency, resolution (number of bits) and noise figure, this is perhaps the most important CCD specification. Dark count refers to that property of all CCD sensors to generate charge in each pixel on its own with time and depending on the temperature. The lower the temperature of the sensor, the lower the dark count. Dark count is usually expressed in electrons per unit of time at a given temperature. It can also be expressed as a current per sensor area at a given temperature. The sole reason that CCDs are cooled is to reduce the dark count effect. For example, a Kodak KAF-0402e and KAF-1602e sensor is specified to have a dark count of 50 electrons per second at 25° C. Taking a one-minute exposure at this temperature would generate 3000 electrons of thermally induced charge! Although the dark count can be subtracted, the dark noise cannot. The dark noise is approximately the square root of the dark count. In this example, the dark noise is about 55 electrons. This could easily degrade any low-light image you attempted to capture over this period of time. [link to www.ccd.com] Other links of interest I found along the way....All About EVE, haha.

muse_1111 User ID: 26558348 United States 08/16/2013 04:48 PM Report Abusive Post Report Copyright Violation | Can someone more knowledgeable tell me what the "Dark" part of the Eve 3-day chart means? [link to lasp.colorado.edu] Quoting: muse_1111 It is showing a spike today and states "Warning: Dark 43.1" Thanks in advance! This has come up before but I forgot the answer, muse1111. A little pain-staking research has given me a clearer idea, although a plain old explanation is hard to find. I'm not a huge techie, so excuse me if this in error. The Dark Count is a sensor-calibration measurement of current (ie,voltage) and resulting thermal properties. The EVE instrument measures solar irradiance in multiple wavelengths in fine detail and has many filters and such. The dark count must be compensated for so as not to degrade the data being recorded. Here is one definition I found from Apogee Imaging which makes CCD imagers for some NASA projects- Dark Count Next to the quantum efficiency, resolution (number of bits) and noise figure, this is perhaps the most important CCD specification. Dark count refers to that property of all CCD sensors to generate charge in each pixel on its own with time and depending on the temperature. The lower the temperature of the sensor, the lower the dark count. Dark count is usually expressed in electrons per unit of time at a given temperature. It can also be expressed as a current per sensor area at a given temperature. The sole reason that CCDs are cooled is to reduce the dark count effect. For example, a Kodak KAF-0402e and KAF-1602e sensor is specified to have a dark count of 50 electrons per second at 25° C. Taking a one-minute exposure at this temperature would generate 3000 electrons of thermally induced charge! Although the dark count can be subtracted, the dark noise cannot.

You are always a wealth of knowlege. I looked for a layman's definition and could not find one, either. |
