Reports from Geisei Observatory<February 24, 2000>

I attempted to observe LINEAR during a very short period of time between the end of evening twilight and moon rise. The nucleus is stellar and the magnitude is 14.7. The tail is 1.5' long in the east-northeast. It is still 3 A.U. (450 million kilometers) from the earth and the tail will certainly become longer than one degree in July when it passes perihelion.
