Hugh M Eye User ID: 39479530 United States 08/17/2013 11:39 AM Report Abusive Post Report Copyright Violation | It looks like Comet ISON will be a flop and may experience the fate of that other over-hyped comet-Elenin. An article based on recent observations, has this to say- "Past performances by dynamically "new" comets [newcomers to the inner solar system], as ISON has turned out to be, have typically been pretty lackluster. With very few exceptions, these comets brighten only very slowly [as they approach, after appearing promising when farther out]. In the lightcurve prediction graph presented by Scarmato, Morales and Gary, their green line corresponds to typical "new" comet behavior. Note that this suggests the comet's brightness barely ever breaks the naked-eye barrier, even at perihelion! Further, if one accepts anything like the green line's absolute magnitude of +9.73 for the comet, then ISON has no chance of surviving its perihelion..." more here: [link to www.skyandtelescope.com] Photos and detailed observation details here: [link to brucegary.net] I hope they're wrong 'cause I love a good comet. Even if it's not bright, it should still be a good show for SOHO and STEREO watchers. |

Hugh M Eye User ID: 39479530 United States 08/17/2013 12:16 PM Report Abusive Post Report Copyright Violation | Scientists using ESA’s XMM-Newton space telescope have discovered that a curious dead star has been hiding one of the strongest magnetic fields in the Universe all along, despite earlier suggestions of an unusually low magnetic field. The object, known as SGR 0418+5729 (or SGR 0418 for short), is a magnetar, a particular kind of neutron star. A small proportion of neutron stars form and live briefly as magnetars, named for their extremely intense magnetic fields, billions to trillions of times greater than those generated in hospital MRI machines, for example. These fields cause magnetars to erupt sporadically with bursts of high-energy radiation. SGR 0418 lies in our galaxy, about 6500 light years from Earth. It was first detected in June 2009 by space telescopes including NASA’s Fermi and Roscosmos’ Koronas-Photon when it suddenly lit up in X-rays and soft gamma rays. It has been studied subsequently by a fleet of observatories, including ESA’s XMM-Newton. Interesting discovery: [link to spacefellowship.com] Great video of Martian moon eclipse...Phobos and Deimos.

joinca User ID: 23928361 United States 08/17/2013 01:06 PM Report Abusive Post Report Copyright Violation | From the SDO blog site: Coronal Holes We see all sorts of things on the Sun and have named them all. Some names, such as chromosphere, make sense only if you speak an ancient language. One that is well named is a coronal hole, which is a dark area in the otherwise bright corona. As we move from solar maximum to the decline toward solar minimum, coronal holes will become a source of many of the disturbances to the geomagnetic field and the ionosphere that we call space weather. But what is a coronal hole and what does one look like? X-ray images of the Sun often show the large dark regions that we call coronal holes. They may extend from the Sun's equator to its poles, a few from pole to pole. In the 1960's they were seen in X-ray images taken by sounding rockets and detected with some radio telescopes. They were first seen clearly in images taken by astronauts on board the Skylab space station in 1973 and 1974. Waldmeier had seen coronal holes in the 1950’s with a green line (Fe XIV 5303) coronagraph that allows the corona to be seen along the limb of the Sun but the X-ray images of the disk of the Sun really showed what they were.
