This week our Sun quiets down from the series of solar storms and flares of last week. Although we were expecting one of the solar storms to hit Earth, it actually was near miss. The storm went just southeast of us. This was quite lucky for the recent Starlink launch because a similar storm from the same region did hit one of our upstream solar wind satellite monitors (STEREO A), and it was actually quite large! Since then the active regions that were firing the solar storms have rotated to the Sun’s farside so things have become quiet again. However, we are still managing to stay in the low 70s for solar flux so amateur radio and emergency responders can expect to hold on to marginal radio propagation this week. GPS reception should also remain good, especially on Earth’s dayside. Plus we have some more fast solar wind coming our way, which could give us a decent show of aurora at high latitudes. Learn the details of the solar storm near miss, see why it was lucky for Starlink, and find out what else our Sun has in store this week!
This week our Sun holds our attention with multiple bright regions flaring and launching solar storms. One of these solar storms is partly Earth-directed and should impact Earth late on August 19 or by midday August 20. This storm is the first “fast” solar storm of this new cycle (compared to the slower, weaker storms during solar minimum). As such it could give us our best chance of aurora views yet down to mid-latitudes! On top of that we are managing to stay in the low 70s for solar flux, despite having a spotless Sun so amateur radio operators should enjoy marginal radio propagation on Earth’s dayside over this next week. Of course radio propagation and GPS reception will be affected once the solar storm hits, but overall the boost in activity lately is a sure sign of Solar Cycle 25 really getting underway! Learn the details of the coming storm, how it will affect you, and see what else our Sun has in store this week.
This week our Sun brings on the brightness with three bright regions in Earth view. One of these, region 2770 is the largest new cycle sunspot we have seen in the northern hemisphere yet! It has also fired a C-class flare, along with a bunch f mini-flares. All of this activity is boosting the solar flux up into the mid-70s. With the additional regions on the Sun’s farside rotating into view soon, we might see the solar flux move higher than its been in several years! On top of that, one of the farside regions is also a solar storm generator so we might get a chance for another solar storm as well over the next few weeks. Learn the details of these new regions, catch up on the remaining aurora photos I promised to show with Comet Neowise shooting through aurora-filled skies during our last solar storm, and see what else our Sun has in store!
This week our Sun gives us a bit of a reprieve when it comes to solar storms. We have a coronal hole in the north, near center disk, but it wont rotate into the Earth-strike zone until next week. This means the solar wind will remain quiet and slow over the next few days so aurora photographers can take a well-deserved breather! However, amateur and emergency radio operators should be smiling this week as we now have two sunspots in Earth view that are boosting the solar flux back into the mid-70s! Along with a few more bright regions that will rotate into view over this next week, radio operators should enjoy better propagation on Earth’s dayside easily over this week and likely in through next as well. Finally, GPS users should also enjoy some decent reception even on Earth’s nightside, thanks to the quiet conditions. Get the details on the new sunspots rotating into view this week and return to Mars with me as we look back at the dust storm that took the life of Opportunity rover, learn why its so important to monitor the weather there, and take a look at the current weather conditions on the Red Planet.
This week our Sun sends us a partially Earth-directed solar storm, which will be followed by a fast wind chaser. (As you can tell from the video, the storm began to hit during the production!) Although not as strong as the storm we had last week, this one should still give decent aurora views at high latitudes, with sporadic views at mid-latitudes as well. In fact, we are already getting field reports showing aurora as far south as Manitoba, Canada! This storm should be followed by some fast solar wind that will likely enhance the effects and lengthen the period of storming over the next several days. Several active regions from the new solar cycle are also rotating into Earth view. One is already visible and is boosting the solar flux back into the marginal range for radio propagation. The other will rotate into view in the next few days will boost solar flux even more– possibly into the mid-70s by mid-next week! This is great news for emergency and amateur radio operators, who could use a lift in radio propagation on Earth’s day side. Learn the details of the solar storm, catch up on stunning storm photos with NEOWISE sailing in aurora filled skies, and see what else our Sun has in store this week!
This week our Sun launched two solar storms, one of which was Earth-directed! The storm has hit, right on time and all through the night people have been getting some amazing aurora shots down to mid-latitudes along with comet NEOWISE (as far south as Michigan in the USA, from what Ive seen thus far)! If you are a member of my Patreon community or follow me on Twitter, you got an early warning of this solar storm and hopefully got some once-in-a-lifetime shots! This solar storm is now waning, but should continue over the next day or so before things return to quiet. As for our star, it continues to be spotless, which means the solar flux is in the high 60s and radio propagation on Earth’s dayside continues to be poor. However, this low solar flux means GPS reception on the dayside should be pretty good– just be careful on Earth’s nightside with the ongoing solar storm. Especially if you are near aurora or near dawn or dusk, your GPS reception will likely be unreliable. Learn more details about this ongoing solar storm, how long aurora will last, and see what else our Sun has in store this week!
This week our Sun gives us a chance for some brief storming due to a remnant coronal hole that has rotated into the Earth-strike zone. In fact, fast solar wind from this coronal hole is hitting Earth now. However, it wont last long so aurora views will be fleeting, even at high latitudes. In addition, a new sunspot has emerged in Earth-view– actually two sunspots emerged, but one of them was too weak to last so it didnt get an official designation by NOAA. The sunspot that did get numbered 2766 is actually a Solar Cycle 24 sunspot, but it is hardly recognizable as such because of the influence of Cycle 25. We will see how long it lasts. Luckily, the several existing bright regions in Earth-view are boosting the solar flux so that radio operators should enjoy marginal propagation on Earth’s dayside again for a short while before things begin to tank. GPS users should also be enjoying some decent reception, especially on Earth’s dayside. Learn the details of the old cycle sunspot, the solar storm launch, catch up on recent pics of noctilucent clouds and Comet Neowise, and see what else our Sun has in store!
This week our Sun continues to keep us on our toes, albeit with subdued activity. We have a partly Earth-directed solar storm on its way that should graze Earth around the 27th. This storm might be intensified by some fast solar wind that should follow. However, it is doubtful any storming will be strong enough to cause much of a disturbance. Any aurora will likely be sporadic and only at high latitudes, so aurora photographers shouldnt get too excited. Also, a couple of promising bright regions have fizzled on the frontside of the Sun, resulting in the solar flux dipping back into the high 60s. Unfortunately, this means poor radio propagation on Earth’s dayside, which is sad news for those emergency radio operators participating in the ARRL field day this weekend. The best news though is for GPS users, as the weak storming and low solar flux means GPS reception should be decent all over the globe. Learn the details of the grazing solar storm, the long, snake-like filament that didnt erupt, and what else our Sun has in store this week.
This week all eyes are on the Sun, but not for the reasons you might think! First we have an annular solar eclipse that will make a ring of fire in the skies over Africa and parts of Asia. (Be sure to check below for links to where you can watch the eclipse live.) Secondly, we have multiple sun-diving comets this week, including the 4000th comet discovered in SOHO’s coronagraphs! Both this comet and the 3999th made a gorgeous close flyby of the Sun a couple of days ago. But dont worry if you missed it because the comet NEOWISE is going to be entering SOHO and STEREO’s coronagraph views in less than a week and we get to watch that comet as it makes its closest approach to the Sun on July 3rd. As for space weather from our star, it’s a reasonably quiet week, with only mild conditions in the forecast. Indeed, it’s the perfect pause to watch these other celestial sights!

This week our Sun gives us more eye-candy as we have two new-cycle, bright regions in Earth view. One is region 2765 and it is the largest new-cycle sunspot we have seen to date. These regions are boosting the solar flux into the low 70s, which means radio propagation on Earth’s dayside is staying in the marginal range. Although there arent any Earth-directed solar storms, we did have a far-side launch of a solar storm this week. the intriguing thing is that it nearly clipped the Parker Solar Probe spacecraft, which is just finishing its 5th perihelion pass (closest approach to our Sun was on June 7th). This solar storm is also making news because it is the first strong “Halo CME” to be seen as we rise out of solar minimum. That it was so clearly seen in Earth-based coronagraphs means that these solar storms are once again growing stronger. Learn the details of this near miss of Parker Solar Probe, catch up on aurora photos from recent solar storming, and see what else our Sun has in store this week!
