On 27 June 1998 an occultation of the 8th magnitude star PPM 236753 (HD 188960)[5] by 248 Lameia was timed by five observers near Gauteng, South Africa. The chords produced a rough size estimate of a 62 × 53 km ellipse.[6] The size estimate based on IRAS Minor Planet Survey data is ~49 km. The rotation rate of this object is commensurate with the rotation of the Earth, requiring observations from different locations to build a complete light curve. These yield a rotation estimate of 11.912±0.001 h with a brightness variation of 0.17±0.01 magnitude in amplitude. The same data set gives a size estimate of 47±3 km, in agreement with earlier measurements.[3]
Infrared imaging of this body shows a relatively featureless spectra that suggests materials that are similar to carbonaceous chondrite meteorites.[7]
