2019-07-16The moon was already undergoing a partial eclipse as it rose over the horizon, so its view was blocked by buildings for some minutes. By the time it became visible from the observer's location the sky was almost dark.
View of the moon at 19:18 local time (GMT -3), together with an intentionally overexposed image to show the color of the shadow cast by the earth.
View of the moon at 19:47, again with an overexposed image.
View of the eclipse at 19:51, close to the end of the umbral phase.
As a bonus, a view of the moon about to set behind the city's horizon the following morning.
All images were taken in Caballito, Buenos Aires, Argentina. As usual, the setup wasn't ideal: handheld smartphone as camera (Motorola Moto G6+), generic 76mm aperture, 700mm focal length, 20mm lens, "slighty" out of focus telescope.
There was heavy cloud cover throughout the event, with only two openings that allowed some visibility of the sun itself: one around 17:00 to 17:20 which was used for some attempts at a clean capture of the sun, yielding this results:
Then just a couple minutes after maximum eclipse the sun cleared the cloud cover through an opening over the horizon, which allowed very few minutes of clear sight of the eclipsed sun. The very low altitude, windy conditions and location of of the observer didn't allow for telescope use, so the only images that could be captured were done using the smartphone covered with the sun filter.
The location of the observer (over a water tank in a building, equivalent to 16 floors up, ~50m over the ground) however was great for taking panoramas which could be used to see the effect of the eclipse over the whole sky, clouds and the city below.

17:44:04 During maximum eclipse, look out for the 360 degrees "sunset" orange sky and the western sky being almost black because of the shadow of the moon while the eastern sky was lit:
17:54:22 After maximum, the still eclipsed sun briefly was exposed just over the northwestern horizon before setting:
The fact that it happened so close to sunset meant that the there was a "double sunset" just minutes apart, as can be seen on this timelapse taken every 1 minute from 17:20 to 18:20, taken with the camera exposure automatic adjustment disabled and artificial lighting turned off.

Stormy clouds over Buenos Aires, including mammatus
Timelapse, one picture every 30 seconds for a predicted storm on the 2018 09 22, taken in Caballito, Buenos Aires, Argentina. Near the end when the sun is going below the horizon Mammatus clouds can be seen forming and coming into view from the north (right side of the picture).
