That's Not a Drone!

I think the drones of interest are the ones that hover over critical infrastructure and military bases, and act evasively.

Ghassali, the Montvale mayor, said law enforcement said in the briefing the drones sometimes appear to fly in a coordinated pattern and can sometimes be in flight for up to six hours.

The drones primarily operate at night, often displaying flashing lights, but they turn off the lights and evade police helicopters when approached, Mayor Michael Melham of Belleville Township said in a Facebook video update on Wednesday.

The red and green aviation lights on regular aircraft are easy to recognize.

The Pentagon spokesman only waved his hand and said, "These are not the drones you are looking for".

Pretty soon (I predict) the military will have effective anti-drone weapons of various kinds. Ukraine has been developing and receiving them for several months now.
After the military gets these anti-drone weapons, they won't be flying around those bases very long.

Drones run amok during a synchronized-drone show in Orlando, Florida:



A kid was hit in the chest by a drone and needed heart surgery as a result.

This involved just a few of the drones in the show, and presumably happened because of a programming error or some kind of random interference. But suppose someone figures out how to "hijack" a whole fleet of these drones. Updated version of Hitchcock's film The Birds, anyone?

Turns out resolving Venus with a normal camera is much more difficult than I expected. Right now, Venus is only 20 arcsec across; a little more than 1% the diameter of the moon. In March it will be 50 arcsec across. By comparison, Jupiter is about 40 arcsec across.

The main problem I'm having is with focusing. Both my Panasonic Lumix point-and-shoot and my Canon EOS R10 SLR boost the screen brightness when manually focusing, blowing-out Venus and making it impossible to focus. I eventually figured out that there was a much dimmer star nearby that was not blown-out, which I could focus on before moving back to Venus. I haven't tried that yet with my Lumix, but here it is with the Canon: 300mm, f/5.6, 1/4000th sec (not a typo; really 1/4000th sec), unedited except for cropping.

This first one is a screen-grab from Photoshop at 400x zoom. You apparently can't resize without Photoshop applying a smoothing filter, and I didn't want to over-represent the image quality.

The next one is with the Photoshop 400% resize and smoothing:

Compared with Starry Night:

I'll try again another night and will still try to take an instructional video if I can get it working on the Lumix.

The UK has had troubling activity as well, so they are bumping up the restrictions around military bases.

Government places drone restrictions over 11 military sites

These sites are all key Ministry of Defence locations, with some linked to nuclear operations or sensitive military activities. The restrictions apply to unmanned aircraft systems (UAS) flying within specific altitudes and distances around these sites.

This move comes after a series of unexplained drone sightings at US airfields across the UK, including two sites associated with nuclear weapons. While no arrests have been made, the incidents have sparked concerns that the activities may be linked to Russia. The authorities are continuing their investigations, although sightings have decreased significantly since late November.

How far are these sightings from Grovers Mill?
Well, since it got brought up, here's an anecdote my Dad told me about that. He was 20 years old in 1938, and at a friend's house listening to the War of the Worlds broadcast. He said that, at some point, he said to his friend "I wonder if anyone believes this is really happening."

It started with military bases. You have to learn to filter the noise from the signal. Why just amplify the noise?
