Does anyone know of a 4G/LTE sos/panic button, one where you can insert a simm and put the number where it can call when a button is pushed? Not just SMS but call because SMS has delays. There is a fence and a small building in the path which can block any wireless bell unit or even wireless...

I changed the illustration because it was done by someone hastily and wrong. The following is right illustration: The following are the references I found (the first two are before perihelion and the last after Perihelion. The Hubble team and James Webb team will publish the full data next...

The image was drawn by an artist just illustrating 1 of the 18 anomalies. That paper was about pre-perihelion which occurs before Oct 29, 2025. But after Perihelion, the same phenomenon occurs, So either the orientation moved with respect to sun or it flips at 180 degrees during perihilion. The...

What url can you see the computational detail or NASA mentioning 3i/Atlas going to pass by Jupiter HIll Radius?

[Mentor Note: OP advised that his acceptable reference in this OP does not support his assertions, and his references in subsequent posts are not acceptable per the PF rules. They have been requested to post acceptable references that support their assertions.] I want to know the classical...

Can someone please compute it. I don't know how to use them. If the Hill Radius is 53.5 million from Jupiter. I want to know if 3i/Atlas will pass say 53.55 or 53.45 million kilometers from Jupiter or slightly inside or outside the Hill Radius.

https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?sstr=3I/ATLAS&view=OPC Above is Jet Propulsion Laboratory data for 3i/Atlas. How do you compute where in Jupiter it will pass in March 16, 2026? I read it will pass exactly at the edge of the Hill Radius of Jupiter at that time.. So want to...

Oh. Problem for restaurant pager is the transmitter is so big and has many buttons and numbers (see below). I just need a transmitter with one button only.

5 year old students are not allowed smartphones in class. And the teacher is so busy to operate the transmitter. Because during dismissal. The teacher is busy lining up 20 students to go to waiting area. The kid can easily press the button. Maybe the Restaurant alert device will work. I'll look...

Hi, I have a 5 year old child in school. My car needs to go inside school compound precisely when they come out of classroom so I don't have to circle for 30 minutes. The dismissal time can be off by 5 to 10 minutes. I have tried letting him use the Samsung Smarttag where he presses the button...

I want to know if the 3 equidistant jets of 120 degrees seen in the 3i/Atlas comet is artifact of the Larson-Sekanina Rotational Gradient Filter. Below is image of the Larson-Sekanina filter output and the original Hubble Telescope image. To those familiar with Larson-Sekanina filter, please...
