HamSCI ***Informal*** Zoom Get-Together, Thursday, 4PM (Eastern)

[Gary Mikitin, AF8A]

Hello HamSCI - We will be opening the HamSCIence Zoom session at its usual time, Thursday, 4PM Eastern, or 2000 UTC, for open, informal discussion of any topic of interest to the HamSCI community:  

• Discussion of past presentations
• Questions (and maybe, some answers) on happenings such as meteor showers, solar eclipses, earth-bound asteroids (!) 
• HamSCI projects:  PSWS, MSQP, SEQP
• Other campaigns, events, meetings, accomplishments, curiosities, observations or findings

We won’t be recording, so come one, come all!

HamSCI Amateur Radio Community Coordinator

[Ronald Kumon]

I have a prior engagement during the meeting time this week, but I would like to place some requests.  The Society of Physics Students and the Sigma Pi Sigma Physics Honor Society are organizing their triennial Physics and Astronomy Congress at the Sheraton Denver Downtown hotel from October 30-November 1.  We are hoping to have more than 1000 undergraduate students, faculty, and other professionals to attend.  As the current president of the Society of Physics Students, I am helping to coordinate some of the activities.  In particular, I am trying to organize a special event station to operate during the Congress, probably mainly on Friday and/or Saturday to promote amateur radio, the Collegiate Amateur Radio Program, and HamSCI.

My questions:

1. Is there anyone in Denver or the surrounding area who might be able to help us to provide some equipment for a station (e.g., radio, antenna, batteries, etc.) and/or operate?  (I'm flying in from Michigan and am a bit cargo-limited.)  If so, please let me know, and I will follow up.

2. Does HamSCI have some information that it would like to distribute?  If so, please let me know, I would be happy to try to do so.

Ron, I suggest you contact the Front Range Six Meter group on groups.io.  They should be able to help with 'local' equipment, operators, etc.  Some of their members are active in the MSQP activities as well as other HamSci projects.

Hello HamSCI - Our weekly informal 'net' will be 'on the Zoom' (we can't say 'on the air') Thursday afternoon.  Attendance may be a bit light, as a few will be traveling, to HamCon Colorado, or, in the case of some snowbirds, from the wet and windy north down to winter homes in Florida.

Reminder:  Our next speaker/program will be Rob Suggs, NN4NT, speaking on meteor scatter, on November 14th.

Will this be available later to stream, for those of us who will be unavailable?

Hetzal - Thanks for the question.

We do not record the informal sessions (on purpose).  We want to encourage people to share relevant experiences and ask questions.  Some would be put off by being recorded for YouTube.

HamSCI presentations by guest speakers - on the second Thursday of each month - those are definitely recorded for the HamSCI youTube channel.

Thanks. Sorry I have to miss it.

Hello HamSCI - Our weekly informal 'net' will be on Zoom later today (Thursday afternoon/evening) at the 'winter time' of 2100 UTC.

Hello HamSCI - Our weekly informal 'net' will be on Zoom Thursday afternoon/evening at the 'winter time' of 2100 UTC.  

Rumor has it that we may have some discussion on GRAPE plots and Doppler shift observations.  All topics relevant to HamSCI are welcome, of course.

[Gwyn Griffiths]

Normand and Joe

Thank you for a splendid thought-provoking talk and set of slides.

I have followed up my comment that the 'flat line' Doppler was possibly reflection from the E region. The attached note shows the results of my automated ray trace simulations for ray elevation angles and Doppler shift.  They do show propagation via the E region at the time of the Flash, with essentially zero Doppler. However,  the F region Doppler was also pretty low by the time of the Doppler Flash.

There is the caveat that these simulations are of the 'climate' of the International Reference Ionosphere for November 2025 and therefore cannot model variations due to TIDs or the Doppler Flash.

Gwyn,

Many thanks for your kind reply and especially for taking the time to analyse more closely the results of the visualizations plots.

I revisited the W7LUX Doppler plot for November 4, 2025. I replotted the Doppler shift using the same timespan used in your Modelled Doppler Shift simulation. 

From the obtained Doppler plot we can observe that your model displays definite similarities with the actual Doppler shift pattern (see page 1 of the attached document). On page 2, I filtered the Doppler plot by simply applying a moving average in order to better show the actual Doppler shifts' respective patterns similarities.

73,

Normand
