Space weather enthusiast, aurora chaser on a budget. Admiring the beauty of nature, with or without camera.
Plenty of sunspot regions on the visible disk, none of which are particularly active though. Right now I'm mostly interested in ARs 4142 and 4143, 2 regions that are currently growing well. Only weak C-flares from these so far, but this could change if they keep developping.
I'm too lazy to do helioviewer but I'm sure these post-eruption arcades would look very nice in detail. @JAL495588? 😅
Our Sun rapid-fire launched multiple #solarstorms today, but they were so close together in time that they look as if they are one structure in coronagraphs. Here is a thread 🧵that discusses the event in detail. The first animation shows the past 48 hours on the Earth-facing…
I noticed traces of a filament eruption this morning (didn't see it lift of though). The location looked promising and indeed there appears to be an Earth directed component according to the M2M WSA-ENLIL+Cone Model. ETA: 2025-07-26T04:00Z
I'm quite excited about this, almost emotional, as this means I should be able to capture the northern lights again soon from my location (57°N). It's like seeing an old friend. 🥲
Some faint rays 10 mins later (21:17 UTC).
Possible glancing blow from this CME, ETA is 2025-07-23T02:00Z. In addition to the anticipated arrival of the CIR and HSS from a transequatorial CH, we might see G1-G2 geomagnetic storm conditions in the days ahead.
Still no aurora in Denmark at 57°N, but a good night for noctilucent clouds. At least astronomical twilight has returned, so maybe next week? Can someone poke the Sun please?
Big scar from the filament that got yeeted into Space this morning, pretty cool.
High solar wind velocity + periods of favorable Bz = faint overhead aurora on the Athabasca aurora cam in Canada, despite the bright moon and low solar wind density. Webcam screenshot from 08:00 UTC.
These coronal holes are getting out of hand. "Massive" doesn't cut it anymore.
AR 4140 producing increasingly strong solar flares, an M2.3 this time.
More promising action on the east limb. The promise of not doing anything in the Earth strike zone? Just a C-class flare (don't care), but also a long duration, eruptive event. This region already showed signs of life yesterday. We'll get a closer look in the next 24-48h.
I've been waiting for this. Some pretty cool images of coronal mass ejections "up close", as the Parker Solar Probe made its closest approach to the Sun so far in December 2024.
This is the view from WITHIN the Sun’s atmosphere! ☀️👀🛰️ NASA’s Parker Solar Probe just released imagery from its closest-ever flyby of the Sun, revealing details in the solar atmosphere that scientists will be studying for years. More: go.nasa.gov/4kA9vSO
