Weekly Propagation Summary – 2020 Jan 06 16:10 UTC

Weekly Propagation Summary (2020 Jan 06 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2020 Jan 06 0724 UTC.

Highlights of Solar and Geomagnetic Activity 30 December – 05 January 2020

Solar activity was very low. New Region 2755 (S34, L=355, class/area Bxo/020 on 03 Jan) developed on the SE limb on 01 Jan but was in decay by 04 Jan. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 30 Dec-04 Jan. Moderate levels were reached on 05 Jan with a maximum flux of 245 pfu observed at 05/1800 UTC.

Geomagnetic field activity was at quiet levels on 30 Dec-02 Jan under nominal solar wind conditions. On 03 Jan, total field increased to 10 nT at 03/0505 UTC with solar wind speed increasing to around 410 km/s. On 04 Jan, a prolonged period of southward Bz was observed reaching a maximum southward deflection of -4 nT. On 05 Jan, total field increased once again to 15 nT at 05/1743 UTC followed by an increase in solar wind speed to near 550 km/s as a negative polarity coronal hole high speed stream (CH HSS) became geoeffective. The geomagnetic field responded with isolated unsettled periods on 03-04 Jan and quiet to active levels on 05 Jan.

Forecast of Solar and Geomagnetic Activity 06 January – 01 February 2020

Solar activity is expected to continue at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels on 08-14 Jan and 23 Jan-01 Feb. Moderate levels are expected on 06-07 Jan and again on 15-22 Jan.

Geomagnetic field activity is expected to reach unsettled levels on 08-10 Jan and 01 Feb. Unsettled to active levels are expected on 06 Jan and14-15 Jan due to recurrent CH HSS effects.

Space Weather and Ham Radio YouTube Channel News:

I am working on launching a YouTube channel overhaul, that includes series of videos about space weather, radio signal propagation, and more.

Additionally, I am working on improving the educational efforts via the email, Facebook, YouTube, Tumblr, and other activities.

You can help!
