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!
This week our star begins to look like it did back during more active times. We have multiple new cycle bright regions both Earthside and farside that are firing mini-solar flares and solar storms. In fact, one region on the farside just launched a large solar storm so we will keep an eye on it as it rotates into Earthview over this next week. We also have a small coronal hole rotating into the Earth-strike zone and it could bring some small pockets of fast solar wind causing weak aurora shows, especially at high latitudes. Solar flux stays in the marginal range this week on Earth’s dayside while GPS/GNSS reception continues to look good all over the globe. See details of this new activity and learn about the serendipitous encounter between the disintegrating Comet ATLAS and Solar Orbiter and where both ATLAS and SWAN will be in the sky this week.
Space Weather gets a bit lively this week starting with some spectacular prominence action on the east limb of the Sun. In addition, our Sun launches a solar storm, which looks like it will go just to the west of Earth, but it could very well enhance the fast solar wind expected to hit over the next couple of days. Aurora photographers, especially at high latitudes could be in for a show. By far the biggest story this week is the appearance of two new bright regions in Earth view. Both of these regions could be signs of the new solar cycle, especially the northern hemisphere region, which has been putting on a nice display of coronal rain as it rotates into view. Although this region has launched several solar storms while on the Sun’s farside, it seems to be dissipating now so we may not see much more activity from it. At least these regions are boosting the solar flux back into the marginal range for radio propagation so radio operators can enjoy a boost in propagation over the next few days. Learn the details of the coming fast solar wind, the near miss of the coming solar storm, and how the new bright regions on the Sun might affect you this week.
We are calming down from a decent solar storm this week– it’s the first large storm we have had in quite a while and it ended an “aurora-drought” at mid-latitudes that had been lingering for months. Now we are feeling the effects of a weak burst of fast wind that is following the storm and it could keep aurora active at high latitudes over the next few days. We also have a mini-solar storm that launched on the 19th and it could slightly enhance the disturbed conditions into the weekend before things calm down. Solar flux is also on the rise thanks to a bright region that is rotating into Earth-view. We are back into the marginal range for emergency and amateur radio communications on Earth’s dayside. GPS reception continues to be good, even at low latitudes on Earth’s dayside. However, there may be some slight issues with GPS reception over the next few days on Earth’s nightside anywhere near aurora or near dawn and dusk. Find out more about the recent solar activity, learn what has happened to Comet ATLAS while we discover the new comet SWAN, and see what else is in store this week.
This week the Sun continues to show more signs of Solar Cycle 25. We have two new bright regions at high latitudes (a hallmark of the new cycle). One region in Earth-view has been firing B-class flares, which is a good indicator that activity is continuing to rise. The other region on the Sun’s farside should rotate into Earth-view in a few days, and should help keep the solar flux boosted into the low 70s. Along with the new bright regions, we also have a coronal hole that will rotate into the Earth-strike zone in just less than a week and it will send us some fast solar wind that could bring more aurora to high latitudes, possibly mid-latitudes too for a short while. Learn the details of the new cycle activity, catch up on aurora photos from recent solar storms, and see what else is in store!
This week space weather stays relatively calm, however, we do have some nice eye-candy, both at Earth and from our Sun. This eye-candy, which includes some gorgeous views of aurora on Earth from recent solar storms & flare activity from the new bright regions on our Sun, should soothe your mind from the craziness in the world right now due to COVID-19. As for our star, two new bright regions from solar cycle 25 have emerged. One has even fired off the first long-duration flare attributed to the new solar cycle. Although this long-duration flare did not bring us a radio blackout or an Earth-directed solar storm, it nevertheless is noteworthy in that it is heralding even more firsts from the upcoming solar cycle. in addition, we also have pockets of fast solar wind that are keeping us at unsettled conditions and bringing aurora to high latitudes over the next several days. Solar flux is remaining in the low 70s, which means radio propagation will stay in the marginal range for radio propagation over the next week. GPS reception also remains good overall through this next week. Learn the details of the recent solar flare and what it means for the coming solar cycle, see some recent aurora that will ease your mind and soul, and see what else our Sun has in store this week.
