  1. Some more magnificent #milwaukee #sunset snaps tonight.

    Sunspots visible in frame three and a small aircraft in the distance on frame four.

  2. Seeing a lot of “red sun” photos that people have taken in the wildfire haze. Here’s a more benign one: it’s an “oops” photo that I snapped while attaching my phone to my telescope to capture some sunspot images a while back. I really like it though!

    (But for some reason it won’t open the pod bay doors.)

  3. Even with a fairly early morning start, the day's heat set in, roiling the air and overheating both astronomer and computer! The astronomer sweated. The computer became glitchy. Results were good, however, and today we're comparing views in color vs. monochrome, and white light vs. hydrogen-alpha. Earth's star was very photogenic today! Tracking sunspots? They are, top to bottom, at active regions 4479, 4478, and 4480. Clouds expected this July Fourth weekend.

  4. The mast and the sun.

    If you zoom in on the sun you can see quite clearly that there are #sunspots visible.

  5. Estuve probando una nueva cámara, la SvBony sv205 con el Samurai, estoy muy conforme con la sensibilidad. Un par de imágenes obtenidas en estos días de las manchas solares y Alfa Centauri (componentes A y B). Muy superior a la que había probado previamente la Celestron NexImage5. La escala de placa es mucho menor con sa SvBony de 0.25"/px cuando con la NexImage era de 0.39"/px. Primeras pruebas, prometo mejorar, filoso filoso #astronomia #astronomy #sun #sol #manchassolares #sunspots #dobles #doublestars #stars #svbony #svbony205 #achromatic #doublet #kasai #kasaiJscope80L #jscope80L #japon #japan #telescope

  6. Three (very) active regions mark the sun’s surface

    Whole-disk view of Sun as it appeared late morning July 2, 2026. The sunspots are nearing Sun’s western horizon (right) but still pose a threat of geomagnetic storms from their flares. This image was captured using our Canon EOS 5D Mk. 4 DSLR, 400mm telephoto lens with 2X extender, and white light Baader film solar filter. False color added.

    Three active regions nearing the western solar horizon have been busy, exploding with multiple flares and coronal mass ejections (CMEs). That solar material is expected to reach Earth beginning July 3 and continuing into the U.S. Independence Day weekend. The CMEs impacting Earth’s magnetosphere could produce auroras. Those blessed with clear night skies should be alert for a possible *quiet* fireworks display! Respect.

    A closeup view of the three active regions mentioned in this post was recorded using our Askar 103APO telescope, and Baader Planetarium Herschel safety wedge. The image was recorded the morning of July 2, 2026 in monochrome and is reproduced here in that state. Photosphere granulation, faculae, and sunspot details are visible here. #Askar #Baader #2026 #astronomy #astrophotography #solar #sun #sunspots
  7. Can you spot the #sunspots here? A very hazy Bochum sunset today, but one from 4478 and both from 4479 are present in the lower right sector of the Sun.

  8. Impressive sunspot commands attention in midday heat

    June 29, 2026 — Morning clouds and the usual trees kept us from working in the cooler, quieter air today so, nearing local (EDT) noon in heat and roiling atmosphere, we took our first shot at Solar Active Region 4478. The region featured a pair of massive sunspots that have been exciting observers lately. Using the Askar 103APO telescope with Baader Planetarium Herschel wedge in white light, we caught the impressive sight. Now aimed squarely at Earth, both AR4478 and 4479 pose a threat of powerful X-Class flares.
