https://www.facebook.com/groups/172438633343696 I tracked down your allsky camera images. When will people realize that jpg is a lossy format and that the pixels are not true representations of the intensities and colors of small regions. I call it “eye candy”, only suitable for eyeballs, or the truly desperate who have nothing else. Please ask him to

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

Can you point to and name some of the nearby stars? Which way is “up” What is the field of view (right and left RA and Dec would help http://aladin.u-strasbg.fr/AladinLite/?target=M%20%2013&fov=0.55&survey=P%2fDSS2%2fcolor When I magnify your image, it has

New to this. You machine tracked and made one 90 minute exposure? No tracking and stacking? I don’t see any grid marks so not sure exactly top bottom left right limits of the region. You used jpg (lossy format) rather than png or some other. But the peak intensity for RGB is about 15

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

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

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

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,

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
