I just checked the data from the Naval Hydrographic Service and I am surprised at how accurate all of this is. It turns out that the time when dawn begins varies quite a bit depending on where you live, but in Buenos Aires that February morning, the morning twilight was at 6:01, and the actual sunrise occurred at 6:27 a.m. It’s interesting how the Sun doesn’t rise all at once, but first there is that phase of partial brightness where the rays disperse in the atmosphere.

What caught my attention the most was that on the same Sunday, the highest temperature reached 26°C at 4:00 p.m., and sunset was quite late, at 7:46 p.m. In other words, we had a fairly long and warm day. This makes a lot of sense if we consider that it was summer in the Southern Hemisphere.

By the way, if you’re interested in what time dawn begins at different times of the year, latitude is key. Near the Equator, it hardly changes, but here in mid-latitudes like Argentina, there are differences of up to two hours between solstices. The Earth’s axial tilt is what causes all of this.

Additionally, that year 2026 brought quite interesting astronomical events: four total eclipses—two solar and two lunar—and several meteor showers like the Perseids and Leonids. The eclipses in March and August were particularly visible from here. If you’re into astronomy, it was definitely worth paying attention to these natural phenomena.
