In this research, we are reporting the light curve of RR Lyrae t ype v ariable star TV Lyn. This star is o bserved in the northern hemisphere and its coordinates are 07:33:31.7 +47:48:09.8. We have used data from Las Cumbres Observatory (LCO) which consists of a worldwide network of robotic telescopes. Photometric measurements were conducted using the SBIG 6303 0.4-meter telescope with a field of view of 29’x19’. Depending on what the color of a star is when different filters are applied to it, the luminosity will change accordingly. Our data consists of four filters, Bessell B (Blue), Bessell V (visual), SDSS-I (Infrared), a nd PAN-STARRS-Z (Near Infrared). Results show that this star has a variability period of 0.2407±0.002 days, metallicity -1.49, and located at a distance of 1362±118 pc. We have used an estimate of the reddening E(B-V) as 0.08. This research is a part of an Our Solar Sibling P roject by an undergraduate student with the help of a faculty advisor and an Our Solar Sibling Project Investigator.
