![]() If you do see Venus today, you'll be glad you did. Suggestion: Read Sky & Telescope's observing tips before attempting any photography. Bright, blinding rays of sunlight can enter your telescope with only a slight accidental nudge of the tripod. "Be careful not to accidentally look at the sun without a solar filter." "Venus was next to the sun in broad daylight," he says. Sebastian Voltmer took the picture from a beach in Sardegna, Italy. Today, Venus is passing almost directly between Earth and the sun-an event astronomers call "inferior conjunction." This is turning the planet into a whisper-thin crescent:ĭr. 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-delta' magnetic field that harbors energy for strong M-class solar flares. ![]()
