[Aavso-photometry] Rj-magnitude for comparison stars

[Alex Golovin]

Hello Gang,

Can anybody provide me a Rjohnson - magnitude of the following stars:

1) TYC 0599-01272-1 =  GSC 0059-00255
2) TYC 4317-01437-1
3) TYC 4317-01578-1

I used these stars as comparison stars for ASAS 002511 and RZ Cas. And now I
need the R-magnitudes.

Can anybody to tell me how to get such magnitudes? Maybe any catalogs in the
Internet...

Thank you for your time!
Yours under the variable sky,
