Each one comes with a greeting card showing the pendant in flight and telling the story of its journey to the stratosphere and back again.Īll sales support hands-on STEM education The students of Earth to Sky Calculus are selling space pendants to support their cosmic ray ballooning program. The sterling silver pendant touched space on April 29, 2023, when it hitched a ride onboard an Earth to Sky Calculus cosmic ray research balloon. SATURN'S CAT PENDANT: It's a far-out gift for the cat-lover in your life: Saturn's Cat. More images: from Philip Smith of Manorville, New York from P-M Hedén of Vallentuna Sweden from Sylvain Weiller of Jerusalem, Israel Select the date and camera (MASTCAM-Z), then start looking for sunspots. Daily photos from Perseverance are available here. Just don't forget, Perseverance saw it first. "A very big sunspot is coming!" says Philippe Tosi of Nîmes, France, who photographed AR3363 and inserted an image of Earth for scale. From where Mars is currently located, Perseverance views more than half the sun's farside, giving it a preview of sunspots still hidden from Earth. That's how the rover spotted AR3363 days in advance.Īstronomers on Earth saw the sunspot for the first time on July 5th: It is able to resolve about 10% of the biggest sunspots into multiple pixels. A recent study shows that Perseverance sees more than 40% of all sunspots despite the fact that Mars is 78 million km farther from the sun than Earth and the rover's camera doesn't put many pixels across the solar disk. When the sun dims, researchers know a dust storm is brewing-one of the most important forms of weather on the Red Planet. Using a solar filter, the rover looks at the sun almost every day to check its brightness. Zoran Knez of Croatia assembled this montage using publically available NASA images On July 2nd, the rover's mast-mounted stereo camera (MASTCAM-Z) tilted up to the sky above Jezaro crater and photographed a deep-black dot on the solar disk: Mars rover Perseverance saw it before we did. Aurora alerts: SMS TextĪ SUNSPOT SO BIG YOU CAN SEE IT FROM MARS:Ī huge sunspot (AR3363) just emerged over the sun's southeastern limb. It was hurled in our direction July 4th by an explosion in the magnetic canopy of sunspot AR3359. NOAA forecasters say that G1-class geomagnetic storms are possible on July 7th when a partial halo CME is expected to hit Earth's magnetic field. 28, 2023, as a show of thanks for years of service and hope for future daisies: 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. Solar wind flowing from this coronal hole could brush Earth on July 8-9. 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. It has not produced a significant flare since it appeared two days ago. Sunspot AR3363 is very large, but so far very quiet.
