Hello!

This shows the Iridium31 Satellite flare as seen from Buenos Aires.

The unusual part is that the flare was in a zone of the sky that we don't see often from the southern hemisphere. Vega, next to the tree remains invisible most of the year from Buenos Aires and barely rises above the horizon during spring.

Corona Borealis is very Alien to me I'm so used to Corona Australis that the "other" corona is a really strange sight.

I guess posting when everybody is sleeping is not a good idea, IŽll propose a time zone change for Argentina!

What do you think about the out of focus stars to make them bigger and the constellations more easy to recognize?
