![]() Get observing tips from Sky&Telescope.īLACK FRIDAY AT THE EDGE OF SPACE: Christmas is coming. That means Williams may be able to see the occultation in the same state as his backyard observatory.īy revealing the shape and surface brightness of Betelgeuse, data from the occultation may help theorists better predict when the famously unstable star will finally explode. The question is, who can observe it? If predictions are correct, Betelgeuse will disappear only inside a narrow corridor stretching from central Asia and southern Europe to Mexico and Florida. So the occultation will definitely happen. "I double-checked the IAU Minor Planet and Comet Ephemeris for 319 Leona and found a marked acceleration across the sky in the next several weeks." "At first I was was shocked at the paltry sky motion of the asteroid, covering only 37 arcseconds in 2 hours, which is way too slow to make it to Betelgeuse 3.5 degrees away by Dec. "This 2-hour gif animation shows 319 Leona en route to Betelgeuse on Sunday morning, Nov. Bill Williams of the Chiefland Astro Village in Florida is monitoring the asteroid's approach: 12th, dark asteroid 319 Leona will pass directly in front of Betelgeuse, allowing observers to make a crude map of the giant star's surface. THIS ASTEROID IS HEADING FOR BETELGEUSE: Astronomers are excited. The first, bright southerly CME shown in the movie above could hit our planet's magnetic field during the late hours of Nov. However, a NASA model already suggests one may be heading for Earth. Just today multiple overlapping CMEs have billowed away from the sun:Īnalysts will have to spend some time unraveling these clouds to determine their trajectories. It is no surprise that solar activity has sharply increased as well. 28, 2023, as a show of thanks for years of service and hope for future daisies:Ī SHARP INCREASE IN SOLAR ACTIVITY: Over the past week, sunspot numbers have increased almost 10-fold with dozens of dark cores now present on the solar disk. Until then, we will maintain AIM's iconic "daily daisy," frozen at Feb. There may be some hope of a recovery as AIM's orbit precesses into full sunlight in 2024. As a result AIM is offline, perhaps permanently. What happened to NASA's AIM spacecraft, which has been monitoring NLCs since 2007? Earlier this year, the spacecraft's battery failed. As the season progresses, these dots will multiply in number and shift in hue from blue to red as the brightness of the clouds intensifies. For the rest of the season, daily maps from NOAA 21 will be presented here:Įach dot is a detected cloud. ![]() ![]() An instrument onboard NOAA 21 ( OMPS LP) is able to detect NLCs (also known as "polar mesospheric clouds" or PMCs). The first clouds were detected inside the Arctic Circle by the NOAA 21 satellite. ![]() The northern season for NLCs began on May 26th. There are no significant coronal holes on the Earthside of the sun. Switch to: Europe, USA, New Zealand, Antarctica 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. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspot complex AR poses a continued threat for M-class solar flares. ![]()
