Pi Cephei is was double star of the month according to https://www.webbdeepsky.com/double-stars/object/pi%20Cep
Pi Gruis is, by all accounts a fine double, but too far south at -46 Dec for UK-based telescopes. I may give it a try when I return to La Palma.
Pi Sco is visible from most of the world. The primary is a spectroscopic binary and the secondary is rather difficult (though well separated) at mag 12.2. The primary does show eclispes, but with a depth of only 30mmag it likely presents a worthy challenge to photometrists willing to stretch themselves. The period is 1.57 days. Anyone up to it this summer?
