02:08:17 David Westman: Hello Raydel, glad you could make it 02:31:17 kent gardner: Is there ambient air inside the polar bear or is there any special gas...is the air heated? 02:32:25 Peter East: How do you define the axes for polarization measurement 02:32:50 Wolfgang Herrmann: Would using Sofia be an option for such measurements 02:41:38 Marcus Leech: PTC heaters use the same steep knee to provide thermal regulation 02:49:17 Bob Stricklin N5BRG: What about the dynamic range of the detector? Do you saturate with such a sharp curve? 02:53:53 Dimitry Fedorov UA3AVR: Are some filters used before bolometer detectors to distinct the frequency bands? 02:58:05 Marcus Leech: Secondary emissions requirements are almost NEVER designed to protect radio astronomy and releated sciences--they're designed to protect "other services". 03:02:01 Kevin Kell * Kim Hay-canada: David, your audio levels seem quite lower than all others. 03:04:19 Stephanie: Hi and 03:04:27 Stephanie: Thank you! 03:04:44 Stephanie: Have you had any interaction with the new Space Force and will they have the same concerns? 03:06:10 Darcy Barron: I have not personally, but there is a strong concern about crowding of satellite orbits and making sure operators have to pay for/include the technology to de-orbit safely 03:08:07 Stephanie: If they share the same concerns there will certainly be an opportunity there in mission and budget!! Goodluck! 03:13:38 kent gardner: Darcy, thank you 03:17:32 Richard Russel: Excellent work Darcy! I am a '80 UNM alumni so keep up the good work for our university! 03:23:38 Tom Azlin W7SUA: Is your receiver antenna pointed NE to have the TX "behind" you? 03:25:25 Tom Azlin W7SUA: page 22 answers my question 03:48:02 Richard Russel: Great work Whit! 03:49:04 kent gardner: What success would we likely have here in the continental US if we tried to duplicate your setup. or is Alaska optimum. 03:57:57 Raydel CO2ESP: Thanks Whit, very interesting! 04:00:48 Mike Otte: On spaceweather.com the aurora is shown as a circle not a column. And the circle expands and contracts with solar activity. Is that circle over the north magnetic pole or the gemetric pole. It looks gemetric. 04:02:20 Whitham Reeve: Mike - The auroral oval is centered on the geomagnetic pole and expands/contracts around that. 04:16:50 Marcus Leech: There's a magnetar on the edge of our Galaxy that is both an FRB and Soft Gamma Ray repeater. 04:17:55 Raydel CO2ESP: excuse my ignorance, what's a Soft Gamma Ray repeater? by its name I assume it re-emits received X-Ray energy? 04:18:34 Marcus Leech: It produces repeating gamma-ray bursts 04:18:45 Marcus Leech: Most of them, as far as I know, are magnetars 04:19:35 Raydel CO2ESP: oh! ok thanks! there are simply too many exotic objects out there, newbie here only familiar with few ones. Thanks Marcus 04:20:25 Marcus Leech: SGR 1935+2154 was detected initially as an FRB by the STARE2 project, but has been confirmed to be a repeating FRB 04:22:28 Wolfgang Herrmann: The relationship between magnetars and FRBs is still a speculation. I will talk about that a bit in my talk later 04:23:25 JPR: Richard can you go into the view mode that shows just your slide? 04:24:37 Marcus Leech: Indeed, there may even be different families of FRBs, but J1935+2154 is definintely a magnetar, and also an SGR 04:24:56 Marcus Leech: And I think that's the one you guys observed? 04:28:40 Wolfgang Herrmann: J1935+2154 is not the one we observerd (we tried, but no succes so far). 06:26:45 Tom Azlin W7SUA: Funny empty shack for me on the photo!!! :) 07:15:22 Whitham Reeve: I have to leave early. Thanks everybody for the conference, and THANKS Dave for organizing it. 07:16:09 Jay Wilson, W0AIR: Thanks for your talk, Whitman. Inspiring. 07:22:19 Raydel CO2ESP: Great presentation Marcus! Amazing the level of performance and science that can be done at amateur level equipment nowadays 07:22:43 Stephanie: Very Interesting! Thank you and please show your website in the chat!! 07:29:59 Richard Russel: Marcus - did you try correlating your FRB candidate with other observatory observations? 07:31:34 Wolfgang Herrmann: It is getting late now here in Europe. So I will say goodbye for today. 07:33:55 David Westman: Thanks for speaking at the conference, Wolfgang! 07:43:32 Bob Stricklin N5BRG: Here is a link with info on paint and reflectivity. Note they mention something called “Cool Coatings System”. https://www.pcimag.com/articles/83468-introduction-to-ir-reflective-pigments#:~:text=Carbon%20black%2C%20iron%20oxide%20black%20or%20copper%20chromite,is%20the%20use%20of%20an%20infrared-reflecting%20black%20pigment. 08:17:24 Raydel CO2ESP: Sorry everyone, my Internet minutes are running out... so I can't stay any longer. 08:17:49 David Westman: Thanks, Raydel - hope you enjoyed the conference! 08:17:51 Raydel CO2ESP: It was real pleasure to participate, and big thanks to all the organizers 08:18:03 Raydel CO2ESP: Yes! it was very great! 08:18:41 Raydel CO2ESP: My apologize to David and Peter for not being able to hear their lectures 08:20:06 Preston Ozmar: David, Neat device. 08:20:21 Raydel CO2ESP: Thanks to SARA and all the participants for this wonderful day 08:20:33 Raydel CO2ESP: Best regards and see you all on the SARA mailing list 08:20:42 Raydel CO2ESP: Bye! and 73! 08:21:55 Darcy Barron: This is really fascinating, I am definitely going to get my students to help build one of these. Already looking at the website to buy the optical components kit! 08:22:12 Darcy Barron: I love the analogy with a radio receiver 08:24:03 Stephanie: Thank You! Important to keep up with solar studies! 08:26:04 Ted Cline - N0RQV: I also want to explore introductory stellar spectrography with …. https://tiedyeastronomer.com/ 09:14:44 Richard Russel: How would you do the analysis if you were looking for an FRB? 09:28:51 Jack Lobingier: Great job Peter, I look forward to reading your entry in the Journal. 09:35:07 David Iadevaia: Thanks all...great conference...I'm off. 09:35:23 Stephanie: Good conference and thanks to the organizers and presenters! I hope to meet in Green Bank sometime! 09:35:30 David Westman: Thanks for your participation, David 09:35:53 David Westman: Yes I hope that we can be in Green Bank in 2023! 09:39:35 Preston Ozmar: Thank you for a great conference!!! 09:39:35 Darcy Barron: Thank you for inviting me! These were all great, interesting talks!
