TX Psc is a very bright, nearby star which is well studied and of interest to professional astronomers. One observer from the BAA-VSS logged a few observations back in 1887 after which the star seemed to have been forgotten about until 1947 when regular visual observations picked up again. There are currently 13,515 observations in the AID, 91.6% of which are visual.

V Crb (15 49 31.31 +39 34 17.9, J2000) is a peculiar orange-red carbon-star (C6,2e (N2e)) with a long history of AAVSO coverage. Since V CrB recently became an asymptomatic giant branch star, it is currently in its hydrogen shell and helium shell burning stage of life. V CrB is in the legacy LPV program and Percy’s list of pulsating red giants (PRGs) exhibiting unusual behavior. The AID currently holds 34,114 observations by 1248 different observers since 1904.
