894-Discovery Night at the Schmidt On a recent night my Catalina Sky Survey teammate Vivian Carvajal found 4 Earth approaching space rocks with our small but mighty Schmidt telescope on Mt. Bigelow, Arizona. These Earth approaching asteroids are all small with an average diameter about the width of tennis court. On their current paths none of them come closer than about 4 lunar distances from our home planet.

Geomagnetic activity is mostly quiet to unsettled (Kp 2–3) with occasional active to stormy intervals (Kp 3–5). Solar flux <100 keeps 20m and 17m stably open all day, 15m good at midday, 10m likely marginal. 40/80m may show stronger fading (QSB) and increased noise. #spaceweather #hamradio #hamr

Impressions from the @esa.int heliophysics modeling workshop this week at ESOC in Darmstadt - amazing to see a roundup of the #spaceweather modeling landscape, as well as the ESOC control rooms, and even a Rosetta/Philae spacecraft model in real size!

Some important #spaceweather factors for human spaceflight being discussed here by @astroroyalscot.bsky.social ☀️👩🏻‍🚀👨🏾‍🚀

Solar activity is low (M 35%), geomagnetic activity will initially be mostly quiet to unsettled (Kp 1–3). However, strong solar winds from a coronal hole may arrive later and trigger an active to stormy phase (Kp 4–5). Till than, conditions are fair to good (15/17/20m). #spaceweather #hamradio #hamr

During the day the solar flux of ~105 units is promising good DX on 15/12m. Starting in the evening, 40m becomes the global DX band; 160/80m promising good conditions by quiet geomagnetic activity (Kp1-2). Disturbances due to coronal holes are not forecast until Friday. #spaceweather #hamradio #hamr

383E-419-ET's Cigar In 2012 as it crossed the orbit of Neptune heading towards the Sun a small space rock was 250 times fainter than can be detected by the Hubble Space Telescope. Five years later, after it had rounded the Sun, it became visible in asteroid hunter's telescopes for about 16 days, as it streaked across our planet's orbit at 37 miles per second, as it continued to move away from the Sun. During that brief period of time it was discovered by the PanSTARRS group in Hawaii, tracked by telescopes around the world, and given the name Oumuamua (“Oh-moo-ah-moo-ah”). Turns out that previous to the discovery observations, sightings too sparse to report, were obtained by my team using the Catalina Sky Survey's Schmidt telescope on Mt. Bigelow, Arizona. In 2024 this unusual space rock will cross Pluto's average distance from the Sun traveling on a path which will take it into deep interstellar space. Since we don't know how Oumuamua could obtained it's current trajectory from processes in our solar system, it is safe to presume that it originated in truly deep space. The mystery of Oumuamua deepened when astronomers measured it's brightness to change regularly by nearly 10 times over a 7.3 hour period of time. If these brightness variations are due to it's shape, and thus the amount of sun light reflected as it rotates, Oumuamua looks like a cigar. Even though Elon Musk's SpaceX Mars rocket could catch Oumuamua, it is more cost effective is to simply wait to discover another one of the several interstellar asteroids which pass by us each year.

#ArtemisII #SpaceWeather

#spaceweather #hamradio #hamr Geomagnetic activity continues to subside and will range from quiet to unsettled (Kp 2–3). Solar activity is low, the solar flux index will be around 115 units. 15 to 20 m are opening reliably, with the 30/40 m bands offering intercontinental DX during the night.

Good evening,
This is my first post on the BlueSky social media application.
I will primarily post my photography interests on this platform
One them is the northern lights as seen from Saskatchewan.

*SpaceWX* Tomorrow is an excellent day for DX on the upper bands. The ionosphere has recovered from the “Easter storm,” and the MUF(F2) will break the 28 MHz mark. A sudden “radio blackout” cannot be completely ruled out, the probability of M-class flares is 55 percent. #spaceweather #hamradio #hamr

#NASA is asking us to reduce #SDO (and JSOC) funding by 50% over 3 years in our senior review (also reflected in the FY27 PBR), but the #FY27 #pbr proposes 100% cuts to SDAC and other Helio archives.

WHO WILL HOST THE 25+ PETABYTES OF SDO DATA???

#spaceweather #FundScience #heliophysics #data

What’s the actual daily dose for astronauts (inside vs outside spacecraft, excluding solar events)?

And how much comes from primary charged particles vs secondary radiation generated in the structure?

#SpaceWeather : #Sun ☀️ activity jumped to moderate over the past day, with 24 total flares. Three of them were M, or moderate flares, and one was edging up toward being an X flare

HF #Propagation Report (SA-MO) - Earth remains initially affected by a high-speed solar wind stream (HSS) and CMEs. Small chance of stormy intervals. Solar activity is moderate; further M‑flares are likely (M 55% X 15% Proton 15%). HF conditions are expected to recover. #spaceweather #hamradio #hamr

Geomagnetic conditions have calmed and are now at G1 levels.

Solar wind speed is is just under 700km/s with the Bz between 0 and -5nT.

Despite a very strong AE (auroral electrojet) and a solar wind speed of 711km/s, the IMF is now in positive territory, meaning very little or no aurora for the time being 😠

#spaceweather

A strong G3 geomagnetic storm is in progress. Aurora may be visible at lower mid-latitudes.

Aurora is being reported by amateur radio operators down to ~52°N over Europe.

#solarstorm update - an interplanetary shock (likely associated with the Apr 1 CME) has arrived at L1 with a speed of ~800 km/s. The total magnetic field remains <15 nT, and Dst shows no significant response so far.

We'll continue to monitor and provide updates if conditions change 🌤️ #SpaceWeather
