A dark, cloud-like, elongated structure in silhouette against the bright textured background of the sun, as captured in hydrogen-alpha light, March 9, 2026.
A thready filament was visible in Sun's southeastern chromosphere March 9, and we were pleased to be able to record it in detail! #Astronomy #sun #solarobserving
The full circle disk image of the sun in hydrogen-alpha light (false color applied) depicts our local star with flame-like prominences at multiple locations around the rim -- the filament/prominence -- filaprom -- feature is at about the fout o'clock position on the disk.
Here's a full-disk view of Sun as it appeared yesterday. We were so excited capturing the filaprom that we let the full disk view go. This really shows off the extraordinary prominence activity that was going on midday, February 16! #sun #astronomy #solarobserving
A new analysis of the Solar Orbiter’s unique views of the Sun’s poles shows how a “conveyor belt” moves within our nearest star.

#Chromosphere of the #sun this afternoon, Aug. 17. Image with Vixen ED70SS, Coronado Isle of Man Ha filter, Player One Neptune M camera. Surprisingly good seeing this time of the day. Usually I take these images in the morning.

The SWPC reported Solar activity was at low levels. A C1.5 flare from beyond the west limb was the strongest event of the period. A CME was observed lifting off the NW quadrant in the vicinity of AR4115. 2/2
#solarobserving #spaceweather
With the days becoming increasingly hot, our shift to early morning Sun shots was a wise move! Clear skies and quiet winds made for very good seeing as we swapped out cameras from the Canon EOS 6D Mk. 2 to the EOS 5D Mk. 4. #sun #sunspots #solarobserving #astronomy

A good day yesterday, Summer Solstice, for @cardiffas.bsky.social at the @bannaubrycheiniog.bsky.social visitor centre showing the public how to view the Sun safely. The weather eventually cleared to allow some excellent views of our nearest star.

New observatories in space and on the ground are providing us with our best views yet of the Sun — providing insight into puzzles that have remained unsolved for decades.

Little happening on Sol *except* for unassuming active region 4087. Looking like nothin' much, AR4087 has been blasting off regular CMEs all missing Earth... so far. In the next couple of days our planet will be within 4087's strike zone so be ready for action!
#sunspots #sun #solarobserving
Our Sun as a light-gray disk. The active region AR4087 is near the mid-left edge of the image and contains two sunspots, one larger than the other. Two much smaller sunspots are near the right-hand, western edge of the disk.
Something new is on the horizon! Active Region 4087 is rotating into view after having recently blasted multiple coronal mass ejections (CMEs) into space. Its aim is off from hitting Earth but in coming days, we will be within the sunspot's strike zone.
#sunspots #sun #solarobserving #solarimaging
Using the Askar 103 APO scope and Spectrum Telescope filter, we are likely saying goodbye to active region 4079 and its large sunspot. A few other spots dot Sun's face but hold a bit less interest. May try again tomorrow to catch 4079 on the western limb.

This is a tight crop of our full-disk image focusing on acrive regions 4081 and, to its right, 4081.
Active Region 4079 will be rolling out of view soon without producing the kind of flares that might be expected from a sunspot of that size. It was an otherwise unremarkable photosphere today.

A full disk image of the sun made on May 7, 2025, showing only three active regions or sunspot groups. Two, to the left of center and one just above center, are fairly unremarkable. AR 4079, however, remains large and in charge, near the sun's western limb which is the right edge of the disk. The solar disk is light gray and the background is solid black.
The day presented unexpected periods of clear sky (between clouds) and decent seeing for our Sun shot. Hoping for better opportunities Friday though our feature of interest may be unavailable.

A tight crop from the full-disk image shows a bit more detail of the large emerging sunspot. Also notable are the sunspot at AR4076 and the rough image texture which is granulation in the solar atmosphere.
The big news is a big sunspot is emerging over Sun's eastern limb. The spot's flare potential is not yet known but the feature is large and may prove to be very active. We shall see. Well, someone will. We'll have clouds.
#sunspots #sun #solarobserving #astronomy
A full-disk image of the sun as it appeared on April 28, 2025. The large emerging sunspot is a dark patch at about the nine o'clock position along the edge of the disk. Other, smaller spots, are scattered across the disk though most of them are in the southern hemisphere.
Sunny skies and mild temperatures today presented us with excellent seeing for our Sun shot. Unfortunately, the rest of the week looks cloudy and damp!
#sunspots #sun #solarobserving #solarimaging #astronomy #spaceweather
The Sun in white light appears as a gray disk with sunspots widely scattered across its surface, in an area at about the central third of the disk.
Sun has broken out in spots! A clear, hot day (83°F) produced very good seeing when we captured our white light image this afternoon. We expect cloudy, even stormy, skies over the next few days.
AR 4070 is being watched as the potential source for M-Class flares.

A full disk image of the sun in false color taken April 1, 2025 showing several sunspots. At about the 9 o'clock position is active region 4048 -- it will move from left to right / west to east on the disk -- over the coming days.
A full disk image of the sun in monochrome taken April 1, 2025 showing several sunspots. The sunspots are labeled with their official designations. At about the 9 o'clock position is active region 4048 -- it will move from left to right / west to east on the disk -- over the coming days.
Today was a rare day with views of Sun. We got a nice look at the sunspot in active region 4048, reported to be growing and the source of M-class solar flares. More days of clouds and rain ahead but it was good to see that our local star is still shining! #sunspots #solarobserving #astronomy
The March 29th partial solar eclipse offers unique opportunities for photography and viewing alike.

Active region 4012 is now capable of producing decent flares as it turns to an Earth-facing position. AR4007 is about to rotate over the limb. We're also seeing a new sunspot just rising over Sun's southeastern limb.

Taking our Sun shot today during a break in the clouds at midday, we enjoyed a temperature of 52°F, powder-blue skies, brisk winds. Seeing was surprisingly good.

The solar disk viewed through a white light filter. A few dark sunspots are visible across the surface and are labeled with their active region numbers.
Among the active regions, AR4007 has developed instability and could become a source of powerful X-Class flares. It is approaching Sun's western limb, however, so it remains to be seen it it fires anything in Earth's direction!
