Orionids by radio detection-UPDATED

Post by Carbon60 »

Radio detected Orionids (Halley's comet debris) which peaked 20/21st October, though detections began sooner (looks like around 14th).

Not as impressive as the Perseids, but detectable nevertheless.

Thanks for looking.

Stu.

Hi Stu,

Very good. I got 20 times the maximum impacts you have recorded. I am still working out what is going on. ¿?

Hi Rainer,

It depends how the count rates are calculated, as the apparent hourly rate can vary significantly depending on the time period over which the counts are collected. Can you plot the growth of the cumulative count over a 24 hour period, or send me your data for October 20th and then I can do a direct comparison with mine?

Cheers

Stu.

That's great Stuart, however these peaks are only marginal compared to baseline rates which surprises me, however, that could be normal and this is why folks get disappointed when nothing happens when they watch the heavens for 30 minutes ;)

Dear all,

My Orionid results over the past few days for comparison.
Moxon ariel working GRAVES with SDR# displaying "pings" on the computer monitor. The display is automatically screengrabbed while the detection system is running and counts are done manually and turned into the graphical displays for interpretation.
Regards to all,
Les

Some updated radio detection data.

Looks like another bit of a spike in the Orionid shower on the 24th, maybe....

Hi Stu,

My former statistics lack of accuracy. Changed my setup. Took out the Low Noise Wideband amplifier and installed a home made Helical Bandpass filter for 174.31 MHz.

My friends set up and mine are quite sunchronized in catdching metoers but still differences.

He is 70 meters lower in height then I am.

Below an image of the Helical Bandpass filter I built for gettting rid pf the RFI [Radio Frequency Interference] downtown. Makes the noise level much flatter and the SNR comes out better. All this thanks to some HAM Radio amateurs in the Ham-Antennas group.io.

My friend did no get more then maybe 5 echoes a day and now he gets nice echoes during24 hours. Similar to me.

His statistics, before and after

Excellent, Rainer. That’s an impressive build. It will be interesting to see how the data stack up over the next couple of months with the Leonids and Geminids coming up.

I’ve noticed that nearly everyone gets different results in terms of numbers and timings of peak showers. So much depends on the specifics of each location and setup, it seems.

Your setup has come along in leaps and bounds, as we say, so really nice work, Rainer.

Hi Stu,

Thanks. It is already very interesting as my friend Downtown has the same set up as I have and the capture is already different and we are only 4.5 km apart.

Same Antennas, same Bandpass filter both built by me, Same RTL-SDR. Same adjustments in SDR# and Spectrum Lab ... :o :o :o

There is a so called eventlogYYYMMDD.txt file with some data. We will compare that data to see better what or how all this behaves.

Me on the left and he on the right
