    SOLAR MINIMUM DEEPENS: The sun has been without sunspots for 32 of the past 33 days. To find a similar stretch of blank suns, you have to go back to 2009 when the sun was experiencing the deepest solar minimum in a century. Solar minimum has returned, bringing extra cosmic rays, long-lasting holes in the sun's atmosphere, and strangely pink auroras. ATMOSPHERIC RADIATION UPDATE: As the sunspot cycle declines, we expect cosmic rays to increase. Is this actually happening? The answer is "yes." Spaceweather.com and the students of Earth to Sky Calculus have been monitoring cosmic radiation in the atmosphere...

    Have you been keeping an eye on Sol lately? One of the top astronomy stories for 2018 may be what’s not happening, and how inactive our host star has become. The strange tale of Solar Cycle #24 is ending with an expected whimper: as of May 8th, the Earthward face of the Sun had been spotless for 73 out of 128 days thus far for 2018, or more than 57% of the time. This wasn’t entirely unexpected, as the solar minimum between solar cycle #23 and #24 saw 260 spotless days in 2009 – the most recorded in a single...

    March 2018 was the least active month for sunspots since the middle of 2009, almost nine years ago. In fact, activity in the past few months has been so low it matches the low activity seen in late 2007 and early 2008, ten years ago when the last solar minimum began

    Known as Transient Luminous Events (TLEs), these unusual features were first spotted by accident in 1989. Minnesota professor John R Winckler was testing a television camera in advance of an upcoming rocket launch, when he realised that two frames showed bright columns of light above a distant storm cloud. The discovery came as a shock to scientists at the time, according to Dr Torsten Neubert, ASIM's lead scientist. "That really surprised all of us. How come this exists and we didn't know it? Airline pilots must have known about it - there are some anecdotal descriptions," the Technical University of...
  • 'Hole' in the Sun Spawns Powerful Solar Wind; Could Amp Up Auroras

    A massive "hole" on the surface of the sun has unleashed a strong solar wind that scientists say may amp up the northern lights in some areas of the U.S. and could disrupt satellite communications over the next few days. Data from NASA's Solar Dynamics Observatory revealed a vast region where the sun's magnetic field has opened up, creating a gap in the sun's outer atmosphere, called the corona. This region, also known as a coronal hole, allows charged particles to escape and flow toward Earth in an increased solar wind. As a result, the U.S. Space Weather Prediction Center...

    A picture of dark sunspots and bright diffuse faculae (best seen around the edges). The study shows how the larger mix of heavy elements leave the spots unchanged, while increasing the contrast of the bright diffuse faculae. Credit: NASA/SDO ============================================================================================================================ The spots on the surface on the sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. However, our understanding of the physics underlying the solar dynamo is far from complete. One example is the so-called Maunder Minimum,...

    NASA’s own data is showing that the star our globe revolves around is dimming. With no sunspots reported in 96 days, the sun is going dark and the evidence could point to an approaching ice age. As the sun gets successively more blank with each day, due to lack of sunspots, it is also dimming, says the website Watts Up With That? According to data from NASA’s Spaceweather, so far in 2017, 96 days (27%) of the days observing the sun have been without sunspots. Today at Cape Canaveral, SpaceXlaunched a new sensor to the International Space Station named TSIS-1....

  • New Solar Research Raises Climate Questions, Triggers Attacks

    08/12/2016 7:17:22 PM PDT · by detective · 20 replies
    Recent research by Professor Valentina Zharkova (Northumbria University) and colleagues has shed new light on the inner workings of the Sun. If correct, this new discovery means that future solar cycles and variations in the Sun’s activity can be predicted more accurately. The research suggests that the next three solar cycles will see solar activity reduce significantly into the middle of the century, producing conditions similar to those last seen in the 1600s – during the Maunder Minimum. This may have implications for temperatures here on Earth. Future solar cycles will serve as a test of the astrophysicists’ work, but...

    Make the most of this summer because it could be your last decent one: winter is coming as the planet enters the most devastating cooling period since the 65-year Maunder Minimum of the 17th and early 18th centuries. This is the dire forecast of Professor Valentina Zharkova, a solar physicist at Northumbria University, who has based her prediction on sun spot activity – known to be a significant driver of global climate – which is currently very low and likely to get even lower during the next three solar cycles. She has spoken about her research and her battle to get it taken...

    New studies flip climate-change notions upside down The sun will go into "hibernation" mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society's annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it - the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova's model is said to have near-perfect accuracy. So what is a "solar minimum"? Our sun doesn't maintain a constant intensity. Instead, it cycles in spans of approximately 11 years....

    The sun has sprung a leak: A hole in the topmost layer of the sun and its magnetic field, the size of 50 Earths, is letting loose an ultrafast solar wind that has kicked off several nights of auroras down on Earth. A new image, from NASA's orbiting Solar Dynamics Observatory, reveals the enormous hole as it was Oct. 10, taken at an ultraviolet wavelength unseen by the human eye. To an ordinary observer, the gaping hole would be invisible, though you should NEVER stare at the sun because serious eye damage can result. The gap in the sun's magnetic...

    Explanation: Not once, but twice the International Space Station transits the Sun on consecutive orbits of planet Earth in this video frame composite. The scene was captured on August 22 from a single well-chosen location in Schmalenbeck, Germany where the ISS created intersecting shadow paths only around 7 kilometers wide. Crossing the solar disk in a second or less, the transits themselves were separated in time by about 90 minutes, corresponding to the space station's orbital period. while the large, flare-producing sunspot group below center, AR 2043, remained a comfortable 150 million kilometers away, the distance between camera and orbiting...

    On Sept. 19, 2014, the five-day average of Antarctic sea ice extent exceeded 20 million square kilometers for the first time since 1979, according to the National Snow and Ice Data Center. The red line shows the average maximum extent from 1979-2014. Credits: NASA's Scientific Visualization Studio/Cindy Starr Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the...
  • Solar activity predicted to fall 60% in 2030s, to 'mini ice age' levels: Sun driven by double dynamo

    07/09/2015 1:51:30 PM PDT · by Ken H · 67 replies
    Summary: A new model of the Sun's solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun's 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Predictions from the model suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the 'mini ice age' that began in 1645. Results will be presented today by Prof Valentina Zharkova at the National Astronomy Meeting in Llandudno.

    It’s been two years since former vice president Al Gore claimed the Arctic would be free of sea ice, and despite fears of a hastening polar “death spiral” earlier this year, the north pole looks like it could have near normal ice coverage this summer. After experiencing its lowest maximum sea ice extent on record, the Arctic ice coverage has rebounded and is currently within its normal 30-year range. Near the end of May 2015, experts warned the Arctic “ice extent was at daily record low levels” because of early ice melting in the Bering Sea and low ice conditions...
