Notes

The molecular cloud Barnard 35 (B 35) with its bright rim on the right (LBN 878) is a part of Sharpless 264, also known as Lambda Orionis Ring, a giant molecular cloud and H II region, which can be seen in the constellation of Orion. Another part of the Lambda Orionis Ring or Sh2-264 is my image of Barnard 30-32 and Cederblad 51.

Associated with Barnard 35 is the young star FU Orionis, surrounded by the yellow nebula Cederblad 59 (Ced 59 or LBN 879). FU Orionis is the prototype of a class variable stars which shows an extreme change in magnitude and spectral type, they are known as FUors. The nebula was formed from an outburst of the star, which is a common feature to most FUors.
