Latest Space Weather News
Moderate Solar Flare
September 23, 2021 @ 07:50 UTC
M2.8 solar flare observed early this morning at 04:42 UTC around AR 2871 in the southern hemisphere. A coronal mass ejection (CME) may have been produced, but could be mostly directed south of the Sun-Earth line. More updates later today. Image below by SDO/AIA.

Solar Update
September 21, 2021 @ 02:10 UTC
Coronal Hole #03 will be facing Earth over the next several days. A high speed solar wind stream flowing from this zone should reach Earth later this week and contribute to a geomagnetic disturbance at higher latitudes. Aurora sky watchers should be alert by weeks end.
