Weekly Propagation Summary – 2020 Mar 09 16:10 UTC

Weekly Propagation Summary (2020 Mar 09 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2020 Mar 09 0528 UTC.

Highlights of Solar and Geomagnetic Activity 02 – 08 March 2020

Solar activity was very low. A new spot group emerged in the SE quadrant on 07 Mar and was numbered Region 2758 (S29, L=229, class/area Cro/020 on 08 Mar). No Earth-directed CMEs were observed during the reporting period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels with a peak flux of 923 pfu observed at 02/1455 UTC.

Geomagnetic field activity ranged from quiet to unsettled levels. Solar wind parameters were slightly enhanced midday on 02 Mar as solar wind speed reached a peak of 488 km/s at 02/1318 UTC, likely due to a connection with an extension off the southern crown, polar coronal hole high speed stream (CH HSS). Solar wind speed gradually diminished to nominal levels by 04 Mar. The geomagnetic field responded with mostly quiet conditions with an isolated unsettled period observed on 04 Mar.

Forecast of Solar and Geomagnetic Activity 09 March – 04 April 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 reach high levels on 19-21 Mar due to CH HSS influence.

Geomagnetic field activity is expected to be reach unsettled levels on 10-11, 18-20, 27-28 Mar and active levels on 19 and 27 Mar due to recurrent CH HSS effects. Mostly quiet levels are expected for the remainder of the outlook period.

Weekly Propagation Summary – 2020 Mar 02 16:10 UTC

Weekly Propagation Summary (2020 Mar 02 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2020 Mar 02 0510 UTC.

Highlights of Solar and Geomagnetic Activity 24 February – 01 March 2020

Solar activity was very low over the period under a spotless solar disk. 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 to moderate levels on 24-25 Feb, 27 Feb, and again on 29 Feb-01 Mar. High levels occurred on 26 and 28 Feb with a peak flux of 2,170 pfu observed at 26/1950 UTC.

Geomagnetic field activity ranged from quiet to active levels over the period. Solar wind parameters were at nominal levels from 24 Feb through early on 28 Feb. At 28/0650 UTC total field began to increase to around 8 nT while the Bz component became variable between +/-7 nT. Solar wind speed initially increased to 503 at 29/0248 UTC before increasing a second time to 573 km/s at 29/1942 UTC. This increase in solar wind parameters was due to a connection to a negative polarity southern crown coronal hole high speed stream (CH HSS) followed by a connection with an isolated negative polarity CH HSS. The geomagnetic field responded with quiet levels on 24-28 Feb and quiet to active levels on 29 Feb-01 Mar.

Forecast of Solar and Geomagnetic Activity 02 March – 28 March 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 reach moderate levels on 02-03, 10-18, 22-28 Mar. High levels are expected on 04-09 and 19-21 Mar due to CH HSS influence.

Geomagnetic field activity is expected to increase to unsettled levels on 02-07, 18-20, 27-28 Mar with active periods likely on 02, 19, 27-28 Mar due to CH HSS activity.

Weekly Propagation Summary – 2020 Feb 24 16:10 UTC

Weekly Propagation Summary (2020 Feb 24 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2020 Feb 24 0149 UTC.

Highlights of Solar and Geomagnetic Activity 17 – 23 February 2020

Solar activity was very low. No active regions with sunspots were observed and no apparent earth-directed CMEs were detected this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 17-19 Feb and high levels on 20-23 Feb.

Geomagnetic field activity reached active levels on 18 Feb and active to G1 (Minor) geomagnetic storm levels on 19 Feb. The enhanced geomagnetic field activity on 18-19 Feb were attributed to the passage of a transient solar wind feature. Active conditions were once again observed on 21 Feb due to negative polarity CH HSS influence. Generally quiet or quiet to unsettled conditions were observed throughout the remainder of the week.

Forecast of Solar and Geomagnetic Activity 24 February – 21 March 2020

Solar activity is expected to be very low throughout the outlook 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 24 Feb-01 Mar, 05-09 Mar, and 19-21 Mar. Normal or normal to moderate levels are expected to prevail throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 26 Feb, 04-05 Mar, and 19 Mar due to the infuences of multiple recurrent CH HSSs. Generally quiet or quiet to unsettled conditions are expected to prevail throughout the rest of the outlook period under a nominal solar wind regime.

Contest Morse Code, Computers, and an Icom Rig

This past weekend (third full weekend in February, February 15-16, 2020) is the ARRL International CW Contest (ARRL DX CW link: http://www.arrl.org/arrl-dx ). This is interesting to my study of radio signal propagation as a columnist and as an amateur radio operator​ because of the contest objective: “To encourage W/VE stations to expand knowledge of DX propagation on the HF and MF bands…” This contest is a good way to get a feel for current propagation–though there are caveats.

Speaking of Morse code and the CW mode on our amateur bands: those of you using CW during contests, do you send by hand or by computer?  Do you copy the code by head, or do you use a computer for decoding?

Do you use a computer for Morse code operation?

Just curious about those of you who use CW. Do you send by hand or computer? Receive by head or computer?

In most contests like the ARRL DX CW contest, I copy by ear, and send mostly by rig keyer. If needed, I use a single paddle key with the Icom rig’s internal keyer to answer unique questions and so on.

Below is a quick demo of using the internal Morse code keyer in my Icom IC-7610 transceiver.

V47T, in the Saint Kitts and Nevis Island in the Caribbean, is calling CQ TEST in the ARRL DX CW contest.

Using the programmable virtual buttons, in which I programmed my callsign, NW7US, and other info, I answer and make a complete contest QSO.

In activity like the Straight Key Century Club (SKCC – https://SKCCGroup.com) K3Y special event, it is all manual. I send my Morse code using a WWII Navy Flameproof Signal Key, and decode with my ears.  It is contextual for me.

How do you do contesting Morse code?  Bonus question: How do you do logging while doing contest operation?
