A large, trans-equatorial coronal hole is currently directly facing Earth! The fast wind from this coronal hole may arrive sometime later this week, sparking minor geomagnetic storms and chances for mid-latitude auroral displays. Here's the recap:

It’s #SunDay! Here’s your space weather report for the week of Feb. 27 - March 5: •0 M-class flares •3 C-class flares •28 coronal mass ejections •0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. It was a fairly quiet week, despite several new active regions rotating onto the Earth-facing side of the Sun. A minor geomagnetic storm is possible tonight, which may produce auroras visible from the northern United States. The source is a coronal hole that has aligned with Earth. Coronal holes are darker, lower density regions on the Sun where fast solar wind escapes. We talked more about them in a post last month!

Watch the 1.9 X-flare in stunning detail, BOOM! We also observe this large trans-equatorial coronal hole, which has been active on the Sun for many months now, soon to hit Earth with a fast gust of solar wind in ~3 days during the Full Moon. G1-G2 geomagnetic conditions expected

It’s #SunDay! Here’s your space weather report for the week of May 8 - 14: •1 M-class flare •1 C-class flare •31 coronal mass ejections •0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The active region we spotted last week (which erupted with an M-class flare and a CME last Sunday) has moved across the Sun and is now center-disk. It’s right next to a coronal hole that unleashed a stream of fast solar wind to Earth. We’ll be watching both regions for continued activity this week. Learn more about space weather:

Happy #SunDay! It's been a busy week for space weather. There have been 35 solar flares, 47 coronal mass ejections, and no geomagnetic storms. This video from NASA's Solar Dynamics Observatory shows several of these flares and coronal mass ejections shimmering forth from the Sun.

Our Sun and Earth have finally calmed down and we are back to low level solar storms and some minor fast solar wind. Here is a nice 4-day view of the Sun from SUVI in 284 Angstroms with the latest GONG magnetic field line model overlay. Old region 4274 is still up to its tricks, firing off the last big flare before rotating off the west limb, and later, launching another storm on the farside! For us, right now we are still getting a little fast wind from a northern coronal hole but that will wane over the next 24 hours. Expect another pocket of fast wind from the coronal hole passing center disk to arrive in about 3 to 4 days. Outside of that, conditions are reasonably calm Earthside, even with the new regions rotating into view in the southeast. Cannot say the same for the farside though!

Our Sun gets busy! Big flare action from Region 4114 continues, causing increased risk for #RadioBlackouts and #RadiationStorms. A wide coronal hole brings extended fast solar wind & #aurora views through this week. Region 4105 launches some gorgeous eye candy near the west limb!

It’s #SunDay! Here’s your space weather report for the week of Feb. 13 - 19: •2 M-class flares •2 C-class flares •40 coronal mass ejections •1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. This week’s moderate (G2 class) geomagnetic storm on Feb. 16 lit up auroras as far south as New York and Wisconsin. The storm was caused by a high-speed stream of solar wind flowing from a massive coronal hole on the Sun, which you can partly see in this video but is best seen in a different wavelength channel from SDO. 👇

It was a fairly calm week on the Sun. A coronal mass ejection last week reached Earth on May 15, triggering a minor geomagnetic storm and leading to aurora sightings across the northern U.S. On May 20, SDO's Helioseismic and Magnetic Imager (HMI) paused normal science operations for a series of routine calibration maneuvers — measurements that keep the instrument's magnetic field and Doppler velocity data scientifically accurate. You can see these maneuvers starting at about 2:29 in the video. Learn more about space weather:

It was a relatively quiet week on the Sun, though a series of coronal mass ejections that erupted on Jan. 8 — just before this reporting period — led to a moderate geomagnetic storm on Jan. 10, with auroras intensifying across high-latitude regions including Iceland and northern Canada. SDO remains in its Earth eclipse period, so you may notice brief blackouts in the video when Earth temporarily blocks the spacecraft’s view. These Earth eclipses will continue daily through Feb. 1.

There were plenty of coronal mass ejections this week, but it was a very quiet period for solar flares. Most flares erupt from active regions — spots that appear brighter here, with swirling loops of solar material — so the flare count and the number of visible active regions are related. This week, there were very few active regions on the Earth-facing side of the Sun. Look how “bare” the Sun looks in the first minute of this video! More on flares & coronal mass ejections:

It’s #SunDay! Here’s your space weather report for the week of June 5 - 11: • 1 M-class flare • 5 C-class flares • 36 coronal mass ejections • 1 geomagnetic storm (as of June 12, though another one is currently forecast for June 13) This video from NASA’s Solar Dynamics Observatory shows the week’s activity. This week’s most powerful flare was an M1.8 on June 6, which erupts from the southeastern (lower left) region of the Sun’s disk at about 0:42 in this video. That eruption also produced a coronal mass ejection that reached Earth three days later, but the bulk of the blast was oriented to the south and east of Earth, so the effect on our planet was minimal.

A reconstruction of the inner heliosphere for the last 18 months and 926 coronal mass ejections. This is a new method: The ambient solar wind at the inner boundary is produced from the near-Earth observations. The CMEs are still determined by coronagraph observations.
