Most every day !
Chemtrail diary, Wednesday 6th Nov 2019.
Chemtrails can be seen on tv programmes, in advertising and pictures of houses for sale and houses for rent. A fine example of the elephant in the room.
You have to be diligent, most days theres sufficient obscuration to necessitate looking up several times to catch a glimpse of anything chemtrail up beyond the obscuring lower cloud layer. I’ve hundreds of decent pics to upload from my camera but I can’t be bothered, therefore lets look at NASA Worldview to give us the juicy bits with minimum effort ie chemtrails.
Look carefully and be sure to discard general media prejudice.

Down to the Channel and its a chemtrail mess ie https://go.nasa.gov/2JTwCsT
Check out the Baltic Sea, looks a bit odd ie chemtrail / geoengineering, no link.
Heres the best of the day for Wed 6th Nov 2019 re chemtrail pics over Europe …. A circular arc of chemtrail over Greece, also radial chemtrail. All is man-made ie chemtrails / geoengineering. Chemtrail link = https://go.nasa.gov/2NopjvB

Click to enlarge, explore, its all a con-job.

A day later we see a repeat of the above.
Crete to Crimea chemtrail quarter arc radial spokes of chemtrail as per day previous; link = https://go.nasa.gov/2K2UhqW

Also what the heck is this strange looking cloud pattern over Italy, southern Adriatic? thursday 7th nov link= https://go.nasa.gov/2NteicE
Vancouver to San Francisco chemtrail geoengineering Thursday 7th Nov 2019 https://go.nasa.gov/2rrokT3
You can see other signs of chemtrail geoengineering, I merely post the quick to find material.
18th Nov 2019.
Lets use this same post for subsequent days of chemtrail. Theres been chemtrails near every day, but much obscured and ill-defined. Today Monday 18th Nov 2019 we can catch up on the thirty hour outage of NASA Worldview, something which has me wondering as yesterday Sunday was blatant obvious chemtrails here in NE England and I felt specifically blocked to the information I need… why, what threat, dear knows!
What we see here below is in my opinion mostly chemtrail augmentation of an existing ‘slight’ cloud presence and its a lot of chemtrail to say the least. In other words chemtrails ride on the back of the clouds, which fools citizens and fools worldview viewers … not that theres much of the latter; yet few register what is happening, again general media have done a ‘good job’ at turning opinion and or free thinking.

Notice in the above the trending SE to NW lines of chemtrail across Northumberland, so obvious from the ground, but look carefully to see this on the worldview image.
Also, Scottish chemtrail Monday 18th Nov 2019, look at this … https://go.nasa.gov/359Crus
We certainly had chemtrail deposition this afternoon, Monday 18th Nov 2018 NE England, clear as day as to what was happening; continuing into dusk, central Pennine flight path as is often the case.
Below is illustrated USA southern states chemtrails … Hermosillo, Phoenix, Tucson chemtrail Friday 15th Nov 2019 … https://go.nasa.gov/2CWm5ti

As is my habit lets go look for chemtrail youtubes that line up with the chemtrails we are seeing above.
Tucson looks to have a healthy refutation of chemtrail, more than usual awareness.
