When I last looked at the comet C/2014 Q2 Lovejoy about three weeks ago, it was near its peak apparent brightness due to its proximity - it passed the closest to Earth just 3 days ago and shined at a magnitude of 4. The comet had now moved away, making its closest approach to the Sun two days before this observation. It was still relatively easy to capture it on the camera, as it's only dimmed back to magnitude 5.

The comet had moved to the constellation Andromeda. 59 Andromeda was below the comet, just outside the enlarged photo. The bright star directly above the comet in the enlarged photo is a magnitude 6.6 star called HR677 or HD 14272.

Some issues now complicate its observation other than the slow dimming. From where I observe, the western and northern sky is lit up with light pollution from the center of the city. And these days, constellation Andromeda is in the western sky, already starting to head toward the horizon after sunset. So I have to observe it in the early night, just when the area of the sky is not too brightened one way or another, at around 9 to 10 PM. The dimmest stars in this photo is around magnitude 12, so I think it was a success.

I've owned a digital camera since November 1999, and I kept every photos and videos I did not immediately delete since then. So I now have more than 15 years of digital memory with me. The first 4 years or so were captured on my first digital camera, a 2-megapixel, 2x optical zoom Kodak DC280, which I bought for 960,000 Won (US$830 at the time). It was a top-of-the-line consumer digital camera, as most cameras back then were of either 0.3- or 1.3-megapixel types. I also remember paying 160,000 Won (US$140) for a 32MB memory card.

I went back to check out some of the earliest photos and revisited the places within them to see how much has changed. With me was my iPhone 6 Plus, which incidentally cost me nearly the same (equivalent of 977,000 Won, US$940 at the time), yet had an 8-megapixel sensor and 128GB of storage.


First up is one of the iconic buildings in the huge Yongsan Electronics Market area. Building 21 of the Seonin Plaza, a.k.a. Seonin Electronics Market had been my favourite place to buy computer gears and parts in my university days.

The 1999 photo shows a dual Pentium III 500 server ad at the entrance, while the 2015 one has a GeForce GTX 740 graphics card ad in its place. The 2015 photo also shows Building 23 behind the right side of the building, which didn't exist until 2007.

Let's move to somewhere underground now.
