They are part of the Leibnitz and Doerfel mountain ranges near the Moon's south pole: UPDATE: Patricio Leon of Santiago, Chile, took a closer look at the mountains and actually identified them. Once these are calibrated, it is possible to correct SDO data for instrumental effects and sharpen images of the sun even more than before.
They reveal how light diffracts around SDO's optics and filter support grids. High-resolution images like these can help the SDO science team better understand the telescope. Note the bumps and irregularities in this close-up image of the Moon's limb: NASA's Solar Dynamics Observatory recorded the 35-minute event:Īt the peak of the eclipse, the Moon covered 67% of the sun, and lunar mountains were backlit by solar fire. Solar flare alerts: SMS Text.ĪN ECLIPSE OF THE SUN IN SPACE (UPDATED): Yesterday, the Moon passed in front of the sun, producing a partial solar eclipse. Bright displays are unlikely, but the nearly New Moon will allow long photographic exposures to capture faint lights. The near miss, if it occurs, could disturb our planet's magnetic field and spark high latitude auroras.
TODAY, A POSSIBLE CME NEAR MISS: A slow-moving CME that left the sun on June 26th could pass close to Earth today. 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/AIAĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. None of these sunspots poses a threat for strong solar flares.
