NANOGrav raw observing data – merging all global sensor networks on the Internet

Hello, I was visiting https://data.nanograv.org/ to see what kind of data you are sharing online.  I am tracking most all the sensor networks on the Internet, especially the emerging ones. If I understand this talk by Steve Taylor at https://www.youtube.com/watch?v=_UptA7pkARo you are only observing at widely separated times for about 30 minutes? He talks about

Comment on How much weight can you remove from your car?

https://www.youtube.com/watch?v=MCiNGmwopx4 I would like to see the bare minimum weight by taking everything. That weight in every car is costing fuel and global warming. Think how many cars are for one person. Need more people? — uber it or share. I drove for years with no one else in the car, carrying all that extra

Is anyone doing continuous quantum measurements? Are you picking up gravity, seismic, magnetic, ELF and other noise?

As the quantum detectors get more sensitivity they should be picking up fluctuations in the local gravitational potential and electromagnetic background fields of the earth. But I have not seen anyone running a detector continuously for the days or weeks or months needed to do the required correlations to trace things out. Nor, do I

Another try to explain why gravimeter magnetometer arrays are important

Andy, Thanks.  I have searched the Internet almost every day for the last 23 years, and have learned never to think something doesn’t exist.   Thanks for confirming that there are likely no permanent magnetometer arrays.  There could still be someone who does it for fun, and doesn’t tell anyone. I wrote some notes below about

Explaining to MathWorks about Infinite Levels of Knowledge and Hover

Jordan, Image Acquisition Toolbox: Your online, and now the attached price list, is not appropriate for “Home” users. Today someone fixed the website issue where the license information was not accessible.  I could not open my account information. Now, when I look at my account information, “Manage Products”, it has  “But Add-Ons” as a working

Comment on finding help on Hackaday.io – building global communities for learning

​Is there a way to ask for help? I have many projects that I would like to try, but often am missing critical pieces that probably are obvious or trivial for someone else. For instance, I want to write algorithms for pan tilt zoom imaging with multiple cameras. The algorithms are relatively easy – but

Comment to Allsky Camera Facebook group about context and daytime uses of cameras

https://www.facebook.com/groups/172438633343696/permalink/877591389495080/ I am looking at daytime uses of all sky cameras. Satellite images are a bit too bulky and not enough resolution for correlations. Need multiple cameras to recover 3D of clouds. I have seen groups aiming at comets, planes, clouds, rain, sky color, daytime astronomy (is possible), sun and moon tracking, shadows, reflections, multispectral,

Active Magnetosphere and Planetary Electrodynamics Response Experiment – website status?

Robin, Haje, I am looking at global sensor networks, and got to magnetotelluric arrays.  For background I was reading about natural signals that can be used for calibration and reference and came to http://ampere.jhuapl.edu/index.html To be explicit, I was at https://en.wikipedia.org/wiki/Birkeland_current and clicked on the link to Project Ampere that took me to https://web.archive.org/web/20050211120508/http://dysprosium.jhuapl.edu/  Then

Comment on Orion Nebula without a star tracker video

Orion Nebula WITHOUT a Star Tracker or Telescope, Start to Finish, DSLR Astrophotography https://www.youtube.com/watch?v=iuMZG-SyDCU I am trying to estimate the time and cost for myself. Today is 19 Jun 2021 for me. Amazon link to Canon EOS 5D Mark III body only is $899.99 + shipping and tax – never used Canon, lots of screens
