Latest Space Weather News
CME Activity Continues
August 18, 2022 @ 19:10 UTC )
Good afternoon. Minor (G1) geomagnetic storm conditions are being observed today in the wake of the ongoing CME / coronal hole stream disturbance. Currently the solar wind speed is above 550 km/s and the Bz/IMF component is slightly south. A coronal mass ejection (CME) observed on Wednesday following an M2 solar flare around AR 3078 was deemed to have an Earth directed component with a possible impact by August 19th. Yet another CME was observed earlier today and appears similar to the one from yesterday. It too may have a slight Earth directed component and should be modeled later today by NOAA/SWPC. Geomagnetic storm conditions could persist during the next several days which would be great news for aurora sky watchers.

Solar activity during the day on Thursday remained at moderate levels with three low level M-Flares and numerous minor C-Flares. Most of the activity was centered around AR 3078 and it will remain a threat for additional flares as it approaches the southwest limb.

Stay tuned to for the latest space weather news and information.

Space Weather Update / Storm in Progress
August 17, 2022 @ 19:00 UTC (UPDATED)
A busy Space Weather Day today!

A minor (G1) geomagnetic storm is now in progress. Solar wind enhancements including a southward Bz component of the interplanetary magnetic field could help fuel things further. A reminder that a watch for moderate (G2) and strong (G3) conditions will also be in effect should things escalate further during the next 24-48 hours. Aurora sky watchers at middle to high latitudes should be alert once dark outside.

UPDATE: The Moderate (G2) Storm threshold was reached at 20:08 UTC (Aug 17). Visible aurora will be likely at middle to high latitudes once dark outside.

ALERT: Geomagnetic K-index of 6
Threshold Reached: 2022 Aug 17 2008 UTC
Synoptic Period: 1800-2100 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate

Eruptive flare activity around AR 3078 continues on Wednesday. An M2.0 solar flare was observed at 13:45 UTC (Aug 17). This looks to be responsible for a bright coronal mass ejection (CME) that so far is headed mostly south of the Sun-Earth line. A further update will be provided once complete cornagraph imagery is available.
