IWLOP #057 - Linné
The actual crater is a small difficult object but the bright halo around it is easy to spot. Linné has been described as a crater, cloud, crater-cone, or pit in a depression. The true nature of this bright and simple crater was settled using Apollo photos.

R1: Linné has a bright halo around a pinpoint. Stands out against the dark Mare Serenitatis floor.
R2: Viewed Linné eight hours before First Quarter.
C1: In brief moments of very good seeing, I was able to see a black dot just slightly off-centre.
Note: Don't know how much detail is required when asked to resolve its small crater. Could see Dorsum von Cotta to its south and the "Valentine Dome" to its NW. Numerous Dorsa on the Mare Serenitatis floor easily seen. The Mare Serenitatis floor, especially in the N-NW, is particularly darker that that of the dorsum and other parts of the E-SE.
