![]() ![]() Such a swarm could be concentrated around the location of the progenitor comet. None have survived.Īstronomers have long wondered if one day a whole cluster of Kreutz fragments might appear-a veritable squadron of comets dive-bombing the sun. ![]() ![]() Since SOHO was launched in 1995, the observatory has watched more than 4000 Kreutz fragments fall into the sun. These are fragments from the breakup of a single giant comet many centuries ago. I'd estimate that at least 30% of the really bright sungrazers we see in SOHO coronagraph images end up having a small leading or trailing companion."īoth comets in Battams' movie are Kreutz sungrazers. ![]() "Saturday's bright comet turned out to have a smaller, leading companion," says Battams. Karl Battams of the US Naval Research Lab took a closer look at SOHO coronagraph images, and this is what he found: WATCH TWO COMETS DIVE INTO THE SUN: Over the weekend, the sun swallowed a comet. Got a picture of the eclipse? Submit it here. Note the crescent-eyed turkey partial eclipse shadow play is lots of fun. Overlapping leaves create natural pinhole cameras, each one casting an image of the crescent-sun onto the ground beneath the canopy. Beneath a leafy tree, you might be surprised to find hundreds of crescent-shaped sunbeams dappling the grass. Eclipse glasses are recommended for safety. WARNING: Even the tiniest sliver of sun left uncovered by the Moon can hurt your eyes. There, the sun will transform itself into a slender crescent. The maximum partial solar eclipse will be in northwest Russia where 86% of the solar disk is covered. All of Europe is in the eclipse zone with the deepest eclipse in the Scandinavian countries: 25th, a partial solar eclipse will be visible from Europe, Asia, the Middle East, and northeast Africa: timetables. PARTIAL SOLAR ECLIPSE ON OCT 25TH: The Moon is about to take a bite out of the sun. NOAA forecasters say there is a 5% chance of M-class solar flares and no more than a 1% chance of X-flares on Oct. None poses a threat for strong flares they all have stable magnetic fields unlikely to explode. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.ĪLL QUIET: There are five sunspot groups on the solar disk. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. These sunspots have simple magnetic fields that pose no threat for strong solar flares. ![]()
