Oy Dra is an RRC star that is located in the constellation Draco, which is estimated to be 550 million years old. (RA 13:08:41.83, Dec 65:40:00.05). As of today, April 17th, this star was last observed 15 days ago, therefore this photometry that I used ranges from 01/29/2012 – 04/02/2024. I was able to use […]
Read more "Oy Dra"Messier 46 (NGC 2437) is a fascinating open star cluster located in the constellation Puppis, rich in both history and astronomical significance. Discovered by Charles Messier on February 19, 1771, it’s situated approximately 5,400 light-years away from Earth and spans about 30 light-years in diameter. The cluster is relatively young, estimated at around 300 million […]
Read more "NGC 2437"I have taken a look at around 14 variable stars and their current classification, and found several that I would like to recommend revision on after looking at newer data. Two of the most notable were the stars ASAS J011054-1857.6 and ASAS J082143-2308.4. ASAS J082143-2308.4, Which I will refer to as “Star 1” from now […]
Read more "Classification Revision of Variable Stars"This unidentified star, ASAS J045816-0013.9, was initially classified by AI as falling between the RRC, EC, and ESD star types. I became one of the first people to properly classify this star, as machines sometimes get confused between different variable star types. After using sky patrol to obtain the CSV file, I uploaded it […]

The globular cluster was discovered by James Dunlop in 1826 and was also observed in 1834 by John Herschel. NGC 5927 has a diameter of about 12 arc mins and an apparent magnitude of +8.86. Observation I collected 15 images from Skynet, of this cluster using telescopes PROMPT-MO-1, Prompt5, and […]
Read more "NGC 5927"PW Boo is a starĀ presently classified as an RR Lyrae variable by the AAVSO International Variable Star Index. Stars of this type are particularly significant in astronomy for their use as standard candles, aiding in the determination of distances within our galaxy. The data for this analysis was sourced from the AAVSO, as […]
Read more "Analysis of PW Boo and Its Classification as an RR Lyrae Star"Variable stars stand out for their rhythmic luminosity changes, which make them essential subjects for astronomical studies. Through Lab 7, I had the opportunity to engage closely with several of these objects, applying data from sources like Gaia and SIMBAD to my own observational data to deepen my understanding of variable stars and their characteristics. […]
Read more "TT Lyn and ROTSE1 J172446.33+435021.7"This lab analyzed variable stars from the American Association of Variable Star Observers’ International Variable Star Index, which had magnitudes between 9 and 12.5. The stars were also classified as potential RR Lyrae variable stars. The goal of the lab was to determine if the classification was correct. In order to do this, we used […]

The star was previously studied by G.Pojmanski, Acta Astronomica (2002) and afterwards, there has not been any research paper on the target. With further research from VSO, I found out that the star was […]

Discovered in 1702 by German astronomer Gottfried Kirch during a comet observation, this globular cluster has intrigued astronomers for centuries. William Herschel was the first to resolve individual stars in the cluster in 1791, counting roughly 200. Messier 5 […]
