Weekly Propagation Summary – 2020 Aug 17 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2020 Aug 17 0158 UTC.
Highlights of Solar and Geomagnetic Activity 10 – 16 August 2020
Solar activity was at very low levels on 10-14 and 16 Aug. Low levels were observed on 15 Aug due to a C2 flare from Region 2770 (N23, L=24, class/area Cso/70 on 07 Aug.
Coronal dimming near S30E30 was observed in GOES-16 SUVI 195 imagery around 16/1700 UTC. An associated CME signature was observed in LASCO C2 imagery at 16/1812 UTC and in STEREO-A COR2 coronagraph imagery beginning at 16/1824 UTC. Analysis of this event remains underway at the time of this writing. No other Earth-directed CME activity was detected during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 10-11 Aug due to coronal hole high speed stream influence. The maximum flux of the period was 2,950 pfu observed at 10/1550 UTC. Normal to moderate levels were observed on 12-16 Aug.
Geomagnetic field activity was at quiet levels throughout the period.
Forecast of Solar and Geomagnetic Activity 17 August – 12 September 2020
Solar activity is expected to be at very low levels throughout the period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 01-07 Sep due to recurrent coronal hole high speed stream influence. Normal to moderate levels are expected for the remainder of the outlook period.
Geomagnetic field activity is expected to be unsettled to active on 30 Aug, unsettled on 19-20 Aug and 29, 31 Aug-all due to recurrent coronal hole high speed stream influence. Quiet levels are expected for the remainder of the outlook period.

Check Out My New SDRplay RSPdx Software-Defined Radio Receiver – Live!
My new SDRplay RSPdx software-defined radio receiver is live, via http://www.sdrspace.com/Version-3, using the SDR Console software (Version 3).
The receivers are online whenever I am not transmitting and when there are no local thunderstorms.
Antenna Port A is a wire antenna (100′), while Antenna Port B is a VHF/UHF discone. Both have an AM Broadcast band reject filter, reducing local AM Broadcast signals by about 30 to 40 dB. I need to use these because the very close KLIN transmitting tower is just miles away and those signals overwhelm the receiver. When I use the signal filters, the local AM Broadcasting signals no longer overwhelm the receiver.
Let me know what you think. Enjoy!
To use my receiver:
Install the latest version of SDR-Console which can be downloaded from https://www.sdr-radio.com/download
Install SDR Console according to the directions given. Once you have the software installed, you will want to add my server.
It takes a little to get familiar with the software, but there are online FAQs on how to begin.
My server is known as, ‘0 NW7US‘ — it will be online when I am not using my antenna systems for transmitting. It will be offline during thunderstorms, or during times when I must use the systems for transmitting.
Software-defined radio is a great way to hear all sorts of communications, from local AM broadcast stations, FM stations, VHF Air Traffic, to shortwave radio stations including amateur radio HF communications.

New SOTA Mountain Goat: Joyce/K0JJW
Congratulations to my wonderful spouse and favorite hiking partner, Joyce/K0JJW, for achieving Mountain Goat status for Summits On The Air (SOTA).

On August 10th, she reached 1000 activator points while activating Pikes Peak (W0C/FR-004). She had quite the pileup on 146.55 MHz. Her best DX for the day was WY7ATH near Cheyenne, WY at a distance of 167 miles. Not bad!
Early on, she always hiked with me on SOTA activations but didn’t start pursuing activator points until the middle of 2017. All of her SOTA contacts have been on the VHF/UHF bands, lots of 2m FM along with 2m SSB, 70 cm and 23 cm FM.
Joyce has activated 181 summits, 112 unique in 19 associations.
She is the second female Mountain Goat in Colorado (after Lynn/KC0YQF) and is the eighth female goat in North America.
