His subsequent trial in Upper Marlboro, Maryland, was condensed to a five-day morning to twilight event to accommodate presiding Judge Ralph W. Powers ' upcoming vacation plans, and held only two and a half months after Bremer shot Wallace.

The purpose of the mission was to train international student volunteer observers to visually track this optically reflective spacecraft during morning and evening twilight intervals for several months, calculate its orbit from shared observations, and derive atmospheric density from drag-induced changes in its orbit over time.

The sun does not appear above the horizon from November 29 to January 14, but significant twilight is experienced for a few hours in the late morning and early afternoon during the latter period.

It was long a voice of conservative viewpoints in contrast to its liberal morning counterpart, The Tennessean, although these views were greatly moderated in the paper's twilight years.

The trip, approximately five hours in length, required a resident of the parish to journey the whole day from twilight to dusk, and cost 375 réis ( departing at four in the morning and returning by sunset ).

This was a " short work containing an estimation of the angle of depression of the sun at the beginning of the morning twilight and at the end of the evening twilight, and an attempt to calculate on the basis of this and other data the height of the atmospheric moisture responsible for the refraction of the sun's rays.
