Curtis (east of Picard in the western part of Mare Crisium)
(formerly Picard Z)
Lat: 14.55°N, Long: 56.77°E, Diam: 2.88 km, Depth: 0.61 km, Rükl: 26
- The tiny craterlet Curtis was also captured on the left parts of Apollo 17's orbital ITEK-panoramic frames AS17-P-2237 and AS17-P-2244. Curtis is the "second one" of the larger craterlets rightward of both frames's left margins.

The white spot east of Picard
Page 159 of T.W.Webb's Celestial Objects for Common Telescopes, Volume 1: The Solar System:
The white spot two diameters east of Picard is a depression (nowadays known as Curtis).
This spot has been found to decrease in size as sunset approaches; at its centre is a small crater (3 km), seen by Gaudibert (1874) and others. This spot is apparently of the same nature as that surrounding Linné.
-Walter Goodacre, F.R.A.S.
- Named for Heber Doust Curtis (1872-1942), an American astronomer.
- This replacement name for a formerly lettered crater was introduced on LTO-62A2 (for which it served as the chart title). It appears in the cumulative list of approved names in IAU Transactions XVB (1973). Since it does not appear in any prior IAU Transactions, it was probably approved at the 1973 meeting. Biographical information was unofficially reported in Ashbrook, 1974. - Jim Mosher
