C/2023 A3 (Tsuchinshan-Atlas) comet on iPhone 16 Pro
Posted by Wesley on
While many comets pass near the Earth every year, most of them don't get bright enough to be easily observable. The Tsuchinshan-Atlas (C/2023 A3) comet was an exception, and it was apparently bright enough to be spotted with naked eye in early October. But during that time the weather was either cloudy or rainy where I live, so nearly missed out on personally observing it.

Thankfully, patience and readiness paid off, and when the skies were cleared up for a few hours during the evening yesterday I got my iPhone 16 Pro out to take photos of the comet from the balcony. The best example of the observation is what you're seeing in the first photo.
Although the comet was no longer visible to the naked eye and there was plenty of light pollution from the city, the camera on the phone was still able to capture the comet with an 8-second exposure under Dark Mode. Marfik (Lambda Ophiuchi), a 3.8-magnitude star is right next to it, and the 4.3-magnitude Sigma Ophiuchi is below it, so you can gauge that the comet was at least as bright as a 3-magnitude star at the time. This is in line with my previous observations where the iPhone's wide-angle lens was good enough to capture a star as dim as magnitude 5.

ISS with Boeing Starliner transits the Sun
Posted by Wesley on
After observing the ISS last year, I was waiting for some interesting changes on board the space station. And this came in the form of the Boeing Starliner spacecraft docking on June 6 as a part of the Crew Flight Test. This test was originally planned to last about a week, but thruster issues kept preventing its return to Earth. This meant that when I finally got the opportunity to make an observation in Daejeon after the monsoon season was over, I could photograph it with the ISS.
Weather in August was still unstable, and forecast for August 15 was cloudy with a chance of rain in many places. But outlook for Daejeon was clear, so drove my car there to make an attempt. And as forecasted, I could see the Sun onobstructed and was able to make a satisfactory observation, as you can see in the composite photo above. The docked Starliner is easily visible as a bump on the left-hand side of the space station's main modules. You can also see the large sunspot named AR3784 near the center of the Sun.

For those who are not familiar with the space station's structure, here's an enlarged photo showing where the Boeing Starliner is currently located within the space station. It's docked to the IDA-2 at Harmony module's forward port. SpaceX Dragon spacecrafts have docked at this location before, so some of my previous observations show that at the same spot instead.
