The Star. (Page 8) duncan124: Dramatic start to autumn from Spaceweather.com " SOLAR SECTOR BOUNDARY CROSSING: High-latitude auroras are possible on Sept. 2nd when Earth crosses through a fold in the heliospheric current sheet. ... On Sept. 2nd, a billion-ton coronal mass ejection (CME) slammed into Earth's magnetic field. Campers in the Rocky Mountains woke up in the middle of the night, thinking that the glow they saw was sunrise. No, it was the Northern Lights. People in Cuba read their morning paper by the red illumination of aurora borealis. Earth was peppered by particles so energetic, they altered the chemistry of polar ice... Hard to believe? It really happened--exactly 156 years ago. This map shows .... ...In fact, a similar flare did occur just a few years ago. On July 23, 2012, a CME of rare power rocketed away from the sun. The storm was in all respects at least as strong as the 1859 Carrington event. The only difference is, it missed. no harm done. The July 2012 event serves as a reminder, however, that extreme space weather is not a thing of the past" I think NASA deliberately played down recent events on the Sun in its Spaceweather reports while it waited to see what was going to happen. duncan124: Don't mention the... "Bookies are hedging their bets on the first flakes of the year, with Ladbrokes offering 5/1 from 20/1 on a flurry anywhere in the UK before midnight on Sunday. Piers Corbyn, director of WeatherAction, said things will take a bitter turn from Saturday especially in Scotland. He said: “There is a chance we could see the first wintry showers of the season between Saturday and Monday. Leon Brown, forecaster for The Weather Channel UK, said: “It is looking rather cool for the rest of the week with temperatures 2 to 4C below normal." http://www.landscheidt.info/?q=aggregator/sources/1 duncan124: Polar Coronal Holes have returned to both poles. These were seen at the beginning of this thread and helped raise the profile of the Suns decline. duncan124: An unperturbed solar disk produces more stable weather on Earth? In this case auroras caused by a ' cleaner ' solar wind? But as I know no one who has actually seen these it is still just a guess. http://earthsky.org/todays-image/this-weeks-bright-auroras duncan124: The suns symmetry goes sidewards! http://spaceweather.com/images2015/21sep15/coronalhole_sdo_blank.jpg?PHPSESSID=crjvle8nmhjcvt47j8mprp0nc5 duncan124: Very large exploding filament misses Earth. Suspicious Observers discuses. https://youtu.bexxxxxxxxxxxx/b-o5vRQGF_Q If the Sun is being magnetically suppressed then it is likely to have these large eruptions and other events, even the 'weather' on the surface of the Sun is now immense. So it is most likely that the Earth is going to be hit by one of these eruptions over the course of the Minimum. Remove the x s to use the link. I don't think SO would like a link on Wireclub. duncan124: "ENORMOUS CORONAL HOLE: A gigantic hole in the sun's atmosphere has opened up and a broad stream of solar wind is flowing out of it. For much of the next week, Earth's environment in space will be dominated by winds flowing from this broad hole. This should activate some beautiful Arctic auroras. NOAA forecasters estimate a 65% of polar geomagnetic storms today as Earth moves deeper into the solar wind stream."Spaceweather.com The polar coronal hole slips southward and the solar wind can now reach Earth. duncan124: Vast valley like feature appears next to the enormous northern coronal hole. http://spaceweather.com/images2015/18oct15/coronalhole_sdo_blank.jpg?PHPSESSID=c7010n8geel32p1lpet5tvjt23 Big reactions continue as if something was making the Sun flicker.  (Post deleted by duncan124 ) duncan124: "VAST HOLE OPENS IN SUN'S ATMOSPHERE: A vast hole in the sun's atmosphere--a "coronal hole"--has opened up in the sun's northern hemisphere, and it is spewing a broad stream of solar wind into space. NASA's Solar Dynamics Observatory photographed the coronal hole during the early hours of Dec. 3rd: " Spaceweather.com http://spaceweather.com/images2015/03dec15/ch.jpg?PHPSESSID=nim0s2dof3h6p48a84laks8qj4 The seasonal south polar Coronal hole returned recently and this could be an early return to last winters dark sun. duncan124: A large geometric object on the face of the Sun. http://spaceweather.com/images2016/12jan16/coronalhole_sdo_blank.jpg?PHPSESSID=7vohsoq5ru9mspecqhot2np7d2 Weather on the super quiet Sun has produced an immense visible feature surrounding an active region? A guess is that the otherwise undisturbed atmosphere has allowed this activity to go on undisturbed.? duncan124: After the large geometric object the deep black polar coronal holes return. More evidence that something is ' pulling ' at the Sun??? duncan124: Last week a large feature was observed across the face of the Sun towards the north. In the last few days a mirror image of it has appeared the towards the south. The southern feature was a long filament while the northern was a string of eruptions but both mirrored each other producing were long diagonal lines. The northern line had a string of small coronal holes while the southern had only one large one which increased after the filament had erupted or faded away. In the past scientist have said that when the erupting material turns away towards a third point it is in fact a large area that is acting the charged area needed for the eruption. I doubt if that is the case and think that it was only how it was observed from Earth that caused it to look that way. It was probably the temperature of the atmosphere that caused the apparent correlation between events on the Sun and weather on Earth duncan124: The Sun keeps quiet. http://climatescience.blogspot.co.uk/2016/02/solar-activity-quietest-in-more-than.html duncan124: " VERY QUIET SUN: Solar activity remains very low. Only a few small sunspots are visible on the solar disk, and none of them has the type of unstable magnetic field ..."spaceweather Sunspots cause warming and fewer sunspots don't. Is this the actual beginning of the Mini Ice Age??? As it has taken several months for the sunspot count to drop to these low levels even if activity on the sun increases it is difficult to see it recovering before next winter. duncan124: " SOLAR ACTIVITY RISES TO A NEW LOW: Lately, the sun has been so quiet that even a minor solar flare would attract attention. On March 23rd, such a flare occured. Sunspot AR2524 unleashed a C1-class explosion. According to NOAA scales of space weather, this raised solar activity from "very low" to "low." What the flare lacked in intensity, however, it made up for in beauty." spaceweather.com 23,3,16 duncan124: Spaceweather keeps on being positive. “ A widely-held misconception is that space weather stalls and becomes uninteresting during periods of low sunspot number. In fact, by turning the solar cycle sideways, we see that Solar Minimum brings many interesting changes. For instance, the upper atmosphere of Earth collapses, allowing space junk to accumulate around our planet. The heliosphere shrinks, bringing interstellar space closer to Earth. And galactic cosmic rays penetrate the inner solar system with relative ease. Indeed, a cosmic ray surge is already underway. (Goodbye sunspots, hello cosmic rays!) “ duncan124: " NO SUNSPOTS: Sunspots vanished 4 days ago, and they still haven't come back. As a result, the sun's X-ray output is flatlining. There hasn't been even a tiny solar flare since last week. Quiet conditions are likely to continue as long as the face of the sun remains blank. Solar flare alerts: text, voice." Spaceweather duncan124: A large coronal hole complex has developed in the first few weeks of June with two polar holes and a large symmetric pattern of holes in the ' northern ' hemisphere. After the long quiet this seems to be significant and could produce CMEs and a wetter summer. ...and if it is a repeated pattern in the Suns decline then it could cause the first serious event of an on coming ice age --- floods. duncan124: " THE SUN IS STILL BLANK: For the fourth day in a row, the face of the sun is blank--no sunspots" spaceweather.com | Science Chat Room 3 People Chatting Similar Conversations |
