NASA will hold a press conference Thursday (Aug. 18) to discuss "new details about the structure of solar storms and the impact they have on Earth," space agency officials said in a statement.

The briefing this week will review new observations from several NASA spacecraft, including the Solar Terrestrial Relations Observatory (Stereo), that currently keep a close eye on the sun, agency officials said in the statement released today (Aug. 16).

Thursday's briefing will be held at NASA's headquarters in Washington and will include presentations from several space weather experts. They include:

The news briefing will begin at 2 p.m. EDT (1800 GMT) and will be broadcast live on the NASA TV cable channel, as well as webcast on the agency's NASA TV website.

The sun is currently in an active phase of its 11-year solar weather cycle (the current season is called Solar Cycle 24) and has erupted with several major flares in recent weeks. The solar cycle will peak in 2013, NASA scientists have said.

ESA Hubble - Dramatic Change Spotted on Faraway Planet



Published on Jun 28, 2012 by camillasdo

Dr. J (aka Dr. Joe Liske) presents the latest discovery about HD 189733b, an exoplanet that has been repeatedly studied by Hubble.

Observations taken in 2011 using Hubble and the Swift satellite showed a flare from the planet's parent star scorching the upper atmosphere and driving it off into space.

Joseph D'Aleo: NASA June 2012 Solar Cycle 24 Prediction

NASA MSFC

The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 60 in the Spring of 2013. We are currently over three years into Cycle 24. The current predicted size makes this the smallest sunspot cycle in about 100 years.

The prediction method has been slightly revised. The previous method found a fit for both the amplitude and the starting time of the cycle along with a weighted estimate of the amplitude from precursor predictions (polar fields and geomagnetic activity near cycle minimum). Recent work [see Hathaway Solar Physics; 273, 221 (2011)] indicates that the equatorward drift of the sunspot latitudes as seen in the Butterfly Diagram follows a standard path for all cycles provided the dates are taken relative to a starting time determined by fitting the full cycle. Using data for the current sunspot cycle indicates a starting date of May of 2008. Fixing this date and then finding the cycle amplitude that best fits the sunspot number data yields the current (revised) prediction.

A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun.

March solar flare was strongest yet seen by Kate Taylor: Updated with NASA YouTube

The solar flare which erupted on March 7 was the most powerful eruption ever observed by Fermi's Large Area Telescope (LAT).

The flare, classified as X5.4, made the sun briefly the brightest object in the gamma-ray sky.

"For most of Fermi's four years in orbit, its LAT saw the sun as a faint, steady gamma-ray source thanks to the impacts of high-speed particles called cosmic rays," says Nicola Omodei, an astrophysicist at Stanford University in California. "Now we're beginning to see what the sun itself can do."

At the flare's peak, it was emitting gamma rays with two billion times the energy of visible light, or about four billion electron volts - easily setting a record for the highest-energy light ever detected during or immediately after a solar flare.

A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies.

NASA: Solar Cycle Prediction (Updated 2011/04/04): Updated by Piers Corbyn

Current prediction for the next sunspot cycle maximum gives a smoothed sunspot number maximum of about 62 in July of 2013. We are currently over two years into Cycle 24.

The predicted size would make this the smallest sunspot cycle in nearly 200 years.

NASA To Make Announcement On Near-Earth Asteroids by Mark Dunphy

Co2sceptic (Site Admin)
NASA says it will hold a news conference at 1 p.m. EDT (6 p.m. GMT) on Thursday to reveal near-Earth asteroid findings and implications for future research. The briefing will take place at NASA Headquarters in Washington.

NASA’s Wide-field Infrared Survey Explorer (WISE) mission, launched in December 2009, captured millions of images of galaxies and objects in space. During the news conference, panelists will discuss results from an enhancement of WISE called Near-Earth Object WISE (NEOWISE) that hunted for asteroids.

The news conference panelists will include Lindley Johnson, Near-Earth Object program executive, NASA Headquarters, Washington; Amy Mainzer, NEOWISE principal investigator, NASA’s Jet Propulsion Laboratory, Pasadena, California; Tim Spahr, director, Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, Massachusetts; and Lucy McFadden, scientist, NASA’s Goddard Space Flight Center, Greenbelt, Maryland.

The conference takes place on the same week that a 13-metre-wide asteroid, named SE58, passed within 0.6 Lunar Distances of Planet Earth. SE58′s approach occured in the early hours of Tuesday 27 September 2011.

The NASA conference also coincides with an ESA (European Space Agency) seminar on Space Situational Awareness, which also be held on Thursday in Warsaw, Poland. Participants will include senior managers, policy-makers and scientists from ESA, ESA Member States, the EU, European institutions and international partner organisations.

WASHINGTON, Feb. 28, 2011 /PRNewswire-USNewswire/ -- NASA will host a media teleconference at 1 p.m. EST on Thursday, March 3, to discuss the first computer model that explains the recent period of decreased solar activity during the sun's 11-year cycle. The recent solar minimum, a period characterized by a lower frequency of sunspots and solar storms, ended in 2008 and was the deepest observed in almost 100 years.

The teleconference panelists are:

Richard Fisher, director, Heliophysics Division, Science Mission Directorate, NASA Headquarters, Washington Dibyendu Nandi, assistant professor, Indian Institute of Science Education and Research, Kolkata, India Andres Munoz-Jaramillo, visiting research fellow, Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass. Delores Knipp, visiting scientist, University of Colorado at Boulder

Supporting information for the briefing will be posted at: www.nasa.gov/sunearth

Audio of the teleconference will be streamed live on the Web at: www.nasa.gov/newsaudio
