RV Tauri stars

Due to the New England winter storm currently affecting the area, phone coverage at the AAVSO may be much reduced until Wednesday. The staff is still available via email, and we suggest using that method to contact us if you need assistance.

Observers may want to take a look at RV Tauri stars as targets of interest. I like them because they change relatively quickly, have a decent visual range and one can make an observation every 2 to 5 days. My favorite bright RV Tauri stars are: R Sct, U Mon, SS Gem, V Vul, AC Her and R Sge. RV Tau, SX Her and TT Oph may also warrant attention. Take a look at some of these variables on the LCG and note lesser degree of data scatter. Being yellow colored stars of spectral classes F and G, there are no major color issues when making an estimate. Clear skies, Kevin Paxson - PKV

R Sct was the first variable star I ever observed, which was about 2 years ago, and it's still among my favorites. I certainly agree with you, RV Tauri stars are interesting, mostly I think due to the quick change in luminosity.
