Variable Stars
Below are observations of the star T Coronae Borealis (T CrB) which has the possibility of brightening to be viewed with the naked eye at some point this year. Currently, my magnitude estimates are all in the area of 10 and determined by using Tycho software. The sheet will be updated as observations are added.

Variable Star R Andromeda
Variable Star R Andromeda
Here is another path you can take in your amateur astronomy journey, variable star observations. This is a view of the star R Andromeda (R And) taken on 14 Nov 22 and 14 Dec 22 showing the change in brightness over that 30-day period. This star will change in brightness from magnitude 5.8 down to 14.9 and back again over a period of 409 days. You can read more about these types of variable stars at (https://en.wikipedia.org/wiki/Mira_variable). While you need specific filter sets to submit your variable star data measurements to variable star organizations, my observations, for the moment, are for my own knowledge bank.

Mira-Type Variable Star R Andromedea
Mira-Type Variable Star R Andromedea
Latest observation data on Mira-Type variable star R Andromedea. According to the ASAS-SN Variable Stars Database, this star has a period of 219 days. I’ve selected four long-period variable stars to observe and record over the next several years. The graph shows observations on this star over the last 75 days.
