Struve 3053

Observation Notes:

This is one of seven double star sketches I submitted to Sky and Telescope for an article in the September 2006 issue, More of My Favorite Double Stars by James Mullaney. I had already observed five of them, but Struve 3053 was a new observation. It was a wonderfully colorful surprise. The primary was a nicely saturated yellow with a deep blue secondary. The PA appeared to be about 80° with a separation of about 24 arc seconds. WDS measurements from 1832 list 70° PA and 15.2 arc second separation. The double can be found listed under HIP 207 and HIP 209. Be sure to take a look at this beauty!
