TOI-1853b Exoplanet Transit (05/16/2024) (John J. DeAlessio III)

TOI-1853b Exoplanet Transit (05/16/2024)

Today I managed to image and record my first ever exoplanet transit using Telescope 5 (T5) from iTelescope's remote observatory in Utah, USA. Even though I only managed to image part of the transit (as you can see from my light curve result when processing the fits files in NASA's EXOTIC transit program), I'm still surprised that I was successful on my first attempt on a target that, according to the AAVSO's Exoplanet Database, I am the first person to submit an observation of the exoplanet, which is TOI-1853b.

You can find that submitted observation (and download all data associated with it) here. The transit finder website was very helpful in planning out my session, and here's the exact transit I managed to partially observe. The transit depth was also very low (only 1.8 parts-per-thousand/ppt), meaning the light curve generated was only a very small dip, but still big enough to be noticeable as a detected exoplanet transit. Overall, I'm glad with how my first exoplanet observation and data processing results came out, since I wasn't sure if I was going to get any usable data at all, and I'm looking forward to hopefully using that T5 remote telescope again in mid-June 2024 to try and observe 2 more exoplanet transits (TIC 257060897 b and TOI-1266b).

I'll be posting some of the images and light curve result from this transit and any future ones I observe on my dedicated astronomy YouTube channel, so if you're interesting in seeing those results, go check it out here!

=== TOI-1853b Information (From NASA's Eyes on Exoplanets) ===

"TOI-1853 b is a gas giant exoplanet that orbits a K-type star. Its mass is 0.23031 Jupiters, it takes 1.2 days to complete one orbit of its star, and is 0.0213 AU from its star. Its discovery was announced in 2023".

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
