[Aavso-photometry] SX Lib sequence star 114!

[Yenal Ogmen]

Hi all,
Last night I observed SX Lib through v-band and while doing photometry I realized that my check star's mag differs from its seq value. This is 114 star with seq value 11.355 for V-band. I checked my previous obs of field and I got approx. same value of 11.15. This means 0.2 mag of difference. This cant be due to error I think. I didnt submit this as an chart error and wanted to ask you all first. Anyone noticed this before?

Thank you.
