Scientific paper

Photoelectric uvby and UBV observations of the Be star λ Eri have been obtained during several seasons. Although the observations are not well suited to period analysis, they are consistent with the spectroscopic period of 0d.701538. The amplitude ranges (in b) from 0m.01 to 0m.08, and on one occasion, was observed to change from the minimum value to the maximum value in only two days. The season-to-season variations are 0m.05 (in b) or less. An understanding of the relationship between the photometric variations and the other variations in this star will require systematic, long-term, coordinated observations.
