Re: TPs and Aurora-Solar Wind correlation?

Whit Reeve
 

Dave - I'll be more vigilant and, when a TP post is made here, I'll try to specifically look at my magnetograms and the SWPC Forecast Discussion.

There have been a few mag storms lately, including today from 0900 to at least 1500 UTC, mostly due to increased solar wind speeds from recurrent coronal holes and the IMF. There was a persistent southward Bz component in the IMF today that enabled reconnection with Earth's field.

Anyway, I'll keep watching.

TP - Mid-day Sep 24 2020 - Heliotown

Thomas Ashcraft
 

Here is a mid-day TP that happened later on Sep 24 2020. Not sure of
lightning conditions at the time of the TP. But the earth's atmospheres
seem to be becoming more active. - Tom


Re: TPs and Aurora-Solar Wind correlation?

Whit Reeve
 

Dave - I'm not yet running RSS but eventually will at HAARP.

In fact, I'm at HAARP right now starting installation of an LWA Antenna - the spectrograph will be connected to it once placed in service.

New term for me today : CYG A . AGN. Active Galactic Nucleus.

(As compared to Cas A . SNR. Super Nova Remnant )

Thanks! - Tom

Nice Tom. Yes, looks like some scintillation in the 2nd spectrogram.

Hard to say if it's SNR scintillation or AGN scintillation.

Cas A is an SNR about 3 kpc away in this galaxy while Cyg A is an AGN
about
70,000 times further away in a different galaxy. Cas A and Cyg A have
similar
flux densities in the upper HF band; I think Cas A still has a slight edge
over
Cyg A. Within a human lifetime that might be reversed as Cas A continues
to
fade. Their positions are close to each other relative to the size of our
antenna beams.

Whit, do you see TPs in your spectrograms way up there at 60° N?

The field has been very quiet until today (24 Sep) when there was K5 and K6
starting around 0700 and continuing through at least 1500:

Re: TPs and Aurora-Solar Wind correlation?

I don't think so, Tom, but has anyone been looking for those correlations? I have not. Does anyone look at the solar wind data and aurora occurrences on a daily basis and compare with our spectrograms?

Yes, I think that’s correct. But the info we’re actually trying to get from the scintillation measurements is the local ionospheric irregularities; so optimally the antennas should be pointing toward the local zenith, but that may not be the optimal directions to Cas A or Cyg A.

Should be phase the antenna to Cas A soon to get better reception of Cas A now that Jupiter is transiting too earlier?

Just a thought

Hi Dave and All,

I'd like to see a systematic collection if Cas A and CygA scintillation data by different SUG and RJ (single-freq) stations, organized by time of year. It is perhaps time to look at the scintillation data to see what science can be done with that data. Accurate timing and calibration of the data are important.

Len, I'm cc'ing you because I'm not sure if you've signed up for the SUG.groups.io.

WOW. Too early to celebrate but on Larry's tip regarding the Jameco power
supply: I switched it out and that seemed to be the problem. I still see
some RFI on the top channel but the diagonal lines are gone.

Spectrogram attached.
