    The eclipse reached 91%, and I captured it from the beginning to maximum, just before the Sun disappeared behind the mountains.

  26. Multiple flares with associated coronal mass ejections (CMEs) have been observed over the past 24 hours, originating from Solar Active Region 4455, shown here. "Closely-spaced impacts on June 5th could produce strong G3-class geomagnetic storms," reports SpaceWeather .com, "with auroras in Europe and the USA at mid-latitudes." Of course, we are expecting cloudy skies, here in Northeast Ohio, when the aurora may occur. #spaceweather #aurora #sun #sunspot #solarastronomy #astronomy

  31. We normally don't post inverted (positive/negative) images of Earth's Sun but today's was so very interesting we've shared it here! The pit shape directly above the large, bold filament is Active Region 4443. Golden colored prominences rise from the western Solar limb -- there's even a bit of "filaprom" visible in the grouping near the top of this image -- silhouetted against blank white (inverted) space. More later, but we wanted to get this one out ASAP.

  36. The Sun, on Sunday morning, observed through clear blue skies, via hydrogen-alpha light. Plenty of prominences present around the rim, and several sunspots / Active Regions provided points of interest for observation. In the second image here, the curved, white patch near a prominence is AR4436 which exploded with an M5.7-class flare a couple of hours earlier -- its CME is likely to miss Earth as it passes by on May 13. This AR bears watching. #solarastronomy

  41. A sunny morning let us observe a fine prominence on the northeastern limb of Earth's Sun. We struggled to adjust the telescope and camera to best resolve the feature not realizing, at the time, the plasma "fountain" was changing -- apparently collapsing -- before our eyes! Pretty exciting, when you think about what's happening, and how large those prominences are! Clouds and deteriorating seeing limited further efforts. #solarastronomy #astronomy #sun

  46. My favorite image from this morning’s observing run is actually a screenshot made during processing. It seems every time we attempted to finalize edits, the software essentially threw up! So before finalizing this one, we made a screen capture and I’m glad! Numerous spicules can be seen along the rim, and the prominence itself has an unexpected dynamical look. Three cone-shaped filament segments add to the scene. #solarobserving #solarastronomy #sun

  56. A little scare, a quick fix

    Our Sky-Watcher HelioStar 76Ha Solar telescope mounted on the observatory’s permanent mount. The focuser, for those new to these things, is operated via the silver knob seen at the lower end of the telescope. Photo by James Guilford.

    A couple of days ago, during a rather ambitious solar imaging session, the focuser on our Sky-Watcher HelioStar 76Ha telescope failed. And by failure, we mean the specialize diagonal that holds an eyepiece or camera would not stay put! The focuser would barely move the assembly and, once released, the diagonal plus camera would … zzzzzzip! … slide outward as far as it could. As one might expect, that sort of thing makes the telescope worthless. Disappointment? Disaster?

    Contacting Agena Astro, the telescope’s seller, their rep. reminded us that the unit was still under warranty and supplied contact information for Sky-Watcher USA’s Support. Sending off an email describing the issue we waited a reply. “Sounds like the focuser might need to be adjusted,” came the reply a short time later. “Don’t worry we have a lot of adjustment with this focuser.” Adjusting three screws on the focuser, as instructed, and within five minutes the system was working good as new!

    The Sun as it appeared via hydrogen-alpha light on April 24, 2026; as imaged using the Sky-Watcher HelioStar 76Ha Solar telescope, and a ZWO ASI monochrome camera. False color applied. Image by James Guilford.

    So there was a little scare. Excellent support provided by the retailer and the manufacturer. A quick fix. And we were able to take advantage of excellent conditions today, making images of our local star!

  59. While our Sun has been at low activity levels in general of late, that doesn't mean it has been without interesting features. Active Region 4419 has been providing the majority of flaring activity, according to the SWPC, and its magnetic fields have the potential for M-Class flares. The bright plage patches are caused by intense magnetic fields, also expressed in the web-like shapes seen in the solar plasma. (Monochrome Images with False Color Applied) #solarastronomy
