Earlier this week, Comet C/2024 G3 (ATLAS) made its closest approach to the Sun.

While doing so, it made a dramatic appearance sweeping through the wide-field LASCO C3 coronagraph of the ESA/NASA SOHO mission over a few days.

Here’s my take, a triplet of Deep Red, Orange, & Blue filter images taken over an hour around 09:00UTC on 14 January, as an RGB composite.

Happy Perihelion Day!
Earth will be closest to the Sun in its current orbit at 11:17 a.m. EST today.

In Earth's current orbit, Perihelion occurs ~14 days after the December equinox, aphelion ~14 days after the June equinox. The timing, on average, shifts a little every year.

Today, in about seven hours of writing this (16:17Z), the #Earth will be at #Perihelion, that is, at its closest point to the #Sun in its orbit. In accordance with Kepler’s Laws of Planetary Motion, it will also be travelling at its top speed whizzing around our star. However, the orbit is almost circular, with an eccentricity of merely 0.0167 and it’s about 1% closer to the Sun than at aphelion and so it’s easy to miss.

Happy #Perihelion to those who celebrate! Enjoy the fact that the sun is slightly closer and slightly brighter than usual today.

Damn, I missed #Perihelion, which was yesterday morning.
