New fundamental parameters for the inner disk open cluster Lyngå 11

We have obtained CCD BVIKC photometry down to V ∼ 21.5 for the open cluster Lyngå 11 and its surrounding field. This previously unstudied object appears to be rich and highly absorbed. A cluster angular radius of 4.5′ ± 0.5′, equivalent to (3.0 ± 0.3) pc, is estimated from star counts in 100-pixel a...
