ASTEROIDAL DAMAGE TO THE EARTH: IMPLICATIONS BY ASTEROIDS ­ RUBBLE PILES. ... 13, Moscow 119892, Russia, E-mail:san@sai.msu.ru In the cause of asteroids ­ rubble piles its effective cross-section of collision to the Earth is determined not by consolidated body, but by cluster of its fragments. Since the stage of rubble ­ piles may be ~108 years (see our communication at previous symposium), it may be significant for estimation the asteroidal damage to the Earth. ...

On 19/20 October 1995 we used GRIM II to attempt spectroscopy of the 2.3 micron CO absorption band in stellar clusters. ... Read Noise Our typical backgrounds in 60s were about 100 DN (about 500 e), and so for faint objects our noise is utterly dominated by the read noise of about 110 e. We can think of three ways to improve this situation: integrate longer; reduce the read noise; or implement multiple reads. ... Flats The quartz lamps were too dim for flats. ...
