| Minor Storm Observed | |
An isolated period of minor (G1) geomagnetic storming was observed at 05:59 UTC Wednesday morning. This was the result of an elevated solar wind stream containing sectors of southward Bz. Visible aurora will remain possible at higher latitudes.

| Bz South / Aurora Watch | |
The Bz component of the interplanetary magnetic field (IMF) has shifted into a south pointing position on Tuesday morning and is helping to disturb our geomagnetic field. Visible aurora will be likely at higher latitudes while it is still dark outside.
ALERT: Geomagnetic K-index of 4
Threshold Reached: 2020 Feb 18 0729 UTC
Synoptic Period: 0600-0900 UTC
Active Warning: Yes

| February 6, 2020 @ 21:40 UTC |
| Minor Storm Watch | |
The current coronal hole stream is moving past Earth near 600 km/s and is helping to generate enhanced geomagnetic activity at higher latitudes. A minor (G1) geomagnetic storm watch is in effect until 23:59 UTC (Feb 6). Aurora sky watchers should be alert once dark outside.
WARNING: Geomagnetic K-index of 5 expected
Valid From: 2020 Feb 06 2030 UTC
Valid To: 2020 Feb 06 2359 UTC
Warning Condition: Onset
NOAA Scale: G1 - Minor

| Aurora Watch | |
A coronal hole in the southern hemisphere (07) is now beginning to partially face Earth. A solar wind stream flowing from this zone could reach our planet by February 6th. High latitude sky watchers should be alert for visible aurora within the next 72 hours.

| Solar Update | |
A new active region (2757) belonging to cycle 24 continues to evolve and is currently producing very minor B-Flares.
In more interesting news, a new region belonging to upcoming Cycle 25 popped up during the past 24 hours and is now turning into view high in latitude off the southeast limb. We will get a better idea on its development during the next day or so. Magnetic image by SDO/HMI.
