    A reminder that "amateur astronomy" is anything but amateur... wow! ☀️🤩

    Sun through my telescope - those sunspots are more than 2 times the size of our planet. Can you imagine what it would be like to stand in the center of one of those? Please don't look at the without proper filters.

    Region 12891. It produced a total of 4 M-Class Flares as it travelled across the disc.

    This is a comet we're looking forward! We should be able to see it in our cameras on STEREO and PSP, and on Solar Orbiter! The latter will be very close to the comet in Dec/Jan, so I'm particularly excited to see those!

    The little white circle in the center of that movie represents the solar limb, so when you consider the size of Earth compared to the size of the Sun, it gives you a feel for the vast size of these eruptions, and the velocity that they travel at (over 3-million mph!)

    Wrapping up an amazing few days of solar flares and CMEs, we've put together this stunning SOHO/LASCO C2/C3 'blended' movie ☀️😍 [via /// B.Gallagher]

    Here we go! Coronagraph images from C3 (the larger-field camera part of SOHO/LASCO) reveal a beautiful, full halo CME! 🔵💨 This is starting to look like an extremely probable face-on impact at Earth. [the other eruption to the right at beginning is a preceding CME from AR 12887]

    It's been far too long since LASCO last saw snow! ❄️🌨️

    Looks like we have an ongoing gradual (long duration) SEP event thanks to the eruption from the central region on the Sun yesterday (AR 12887)! ☀️🛰️

    FINALLY! AR 12887 produced a global eruption (associated with an X1.0 flare). The dark part of this animation represents coronal dimmings due to a CME, which may arrive at Earth on Halloween, in addition to a filament that went off south.

    Updated animation of Comet 29P Outburst. Now running from Sep 28 to Oct 10. Scale is just under 6' high, with north at top.

    oh it actually looks pretty good... yay! Meant to say: the random flashes on the left edge are just processing artifacts. This is pretty heavily processed data.

    I know Twitter compression will butcher this gif, but I'll try anyway. It's a really nice CME seen by our HI-1 camera on STEREO-A a couple of days ago. (The bright vertical streak is caused by the star Pollux.) ☀️

    Oh, and speaking of Geminids... You may recall we had a press release about PSP/WISPR observation of them shortly after launch: e.g. Well, we've got enough new data now that I hope to get some new/updated results published this fall. Stay tuned!

    Twitter compression will annihilate that movie, so you can see/download it here:

    If you've seen any of our WISPR movies and wondered what all the streaks are, many of the answers are contained in that paper. Most folks assume they're cosmic rays but they're nearly all dust streaks - mostly secondary dust created from meteoroids hitting the spacecraft.

    Another great result from - this time relating to the zodiacal cloud AND the Geminid meteor shower! Full paper is here (open access)

    dust grains in the zodiacal cloud
    Using data from 's , scientists have assembled the most complete picture yet of the inner structure and behavior of the zodiacal cloud — a large cloud of space dust that swirls throughout the solar system:
