![]() ![]() 13th, Venus and the sun will be separated by a little more than 7 degrees. At that time the night side of Venus will face Earth, with only a fringe of sunlit cloudtops visible around the planet's circumference.Īt closest approach on Aug. ![]() 13th, Venus will pass almost directly between Earth and the sun. This rare event is a sign that Venus is approaching inferior conjunction. "I am not unhappy with the result because it took more than 30,000 images of which only 20% were kept to be able to present it to you." "It's very subtle but it's there!" says Favre. With only a little extra contrast, his photo reveals that Venus is now a ring: French astrophotographer Didier Favre succeeded on August 10th. It's a holy grail of amateur astronomy: To photograph Venus so close to the sun that its nightside is framed by an annulus of light. Book a campsite and enjoy the show: Observing tips. The nearly New Moon will make the display unusually easy to see from dark-sky sites. 12-13, Earth will pass through a stream of debris from Comet 109P/Swift-Tuttle, causing dozens of meteors per hour to streak out of the constellation Perseus. 28, 2023, as a show of thanks for years of service and hope for future daisies:įorecasters are predicting the best Perseid meteor shower in years this weekend. 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 equatorial 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 AR3395 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. ![]()
