RV Tauri stars

The membership database is currently undergoing upgrading/testing. Web functions that involve an interface with the member database (webobs, etc.) may experience intermittent problems. We hope to have this issue resolved within 24 hours (by 5pm Eastern Time on October 1st or 12:00 UT). Thank you for your patience.

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.
