Yet in Quarantine, Life Blossoms!
May 19th, 2020 | 
Author: About a month ago, I asked,
“What is going on with you during this challenging situation?” and, “How do you use amateur radio, now that we are all stuck at home? Are you using ham radio more, now? Less?“
I am moved to say, “Thank you, to each of you who commented and even those who made a video response. I sure appreciate it!“
During that video blog (or, Vlog), back a month ago (link: Chat From a Quarantined Software Engineer – Welfare Check!), I mentioned my need for dental surgery.
I did have to have the tooth removed. It was completely split down the middle (top to bottom), down to the root. There was no justifiable way to save the tooth.
I now am missing two bottom back-most teeth, and one bottom, back-most tooth. I can report that I have healed up nicely. I am starting to enjoy a hamburger or two.
Through all of this, I’ve still been working. Also, I’ve been involved with a LOT more ham radio–especially with Morse code activities.
How has the last month treated you? After watching this new video (below), please leave a comment or two, or three; let hear from you, okay?
More than anything, please leave a comment to let me know how you are doing. I hope to hear from you.
Here’s the video:

Weekly Propagation Summary – 2020 May 18 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2020 May 18 0322 UTC.
Highlights of Solar and Geomagnetic Activity 11 – 17 May 2020
Solar activity was very low. The solar disk was spotless. Beginning on 15 May, a rise in x-ray flux background was observed as two plage regions emerged on the ENE and ESE limbs, possibly the return of old Regions 2762 (N23, L=338) and 2761 (S18, L=332). 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 with a peak flux of 203 pfu observed at 16/0220 UTC.
Geomagnetic field activity was mostly quiet with an isolated unsettled period observed late on 12 May. Solar wind parameters were at nominal levels with solar wind speed ranging from 282-354 km/s while total field was between 1-8 nT.
Forecast of Solar and Geomagnetic Activity 18 May – 13 June 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 to moderate levels for the outlook period (18 May- 13 Jun).
Geomagnetic field activity is expected to reach unsettled levels on 19-20 May due to weak coronal hole high speed stream activity (CH HSS). Mostly quiet conditions are expected for the rest of the period.

Weekly Propagation Summary – 2020 May 04 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2020 Apr 20 0123 UTC.
Highlights of Solar and Geomagnetic Activity 13 – 19 April 2020
Solar activity was very low throughout the reporting period. No sunspots were obseved on the visible disk and no Earth-directed CMEs were observed in available coronagraph imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the reporting period.
Geomagnetic field activity ranged from quiet to unsettled. Unsettled levels were observed on 14-15 Apr in response to several periods of prolonged southward Bz. The remainder of the reporting period observed quiet conditions.
Forecast of Solar and Geomagnetic Activity 20 April – 16 May 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 be at mostly normal to moderate levels. 29-30 April will likely observed high levels in response to coronal hole influence.
Geomagnetic field activity is expected to be at quiet to active levels. Active levels are likely on 20 Apr, 27 Apr and 05 May; unsettled levels are likely on 21-23 Apr and 30 Apr. All enhancements in geomagnetic active are in response to multiple, recurrent CH HSSs. The remainder of the outlook period is expected to observed quiet conditions.

Chat From a Quarantined Software Engineer – Welfare Check!
This is a welfare check on you. Please leave a comment on how you are faring, what is happening in your situation with the lock-down.
Are you quarantined? Working from home? Did you lose your job? How are you doing during this crazy time?
What is going on with you during this challenging situation?
I talk about what I’m doing, too. I’m quarantined at home. I can work from home, as I am a senior software engineer. I can do my job by remote access to a virtual workstation, through a secure VPN connection. I’m blessed that I still can work during this lock-down.
But, I have a medical emergency – a dental problem – and trying to be seen by a dentist is difficult, because all of the local dentists were told to shut down their daily business and quarantine. Only emergency appointments are being made! I was finally, after two days of phone calls, able to schedule an emergency visit to my dentist!
I want to know: How do you use amateur radio, now that we are all stuck at home? Are you using ham radio more, now? Less?
Please leave a comment to let me know how you are doing, and answer the other questions, too. I hope to hear from you.
I hope to meet you on the shortwave amateur radio bands. I am usually using Olivia, or Morse code CW. More information about Olivia: http://OliviaDigitalMode.net.
Be healthy, be safe, stay sane!
