Proposal Identification No.: ... At mid-latitudes, OI 844.6 nm emission brightness is a potentially excellent proxy for [O], and recent improvements to its forward emission model warrant renewed effort to pursue ground-based sensing using this unique emission. ... To this end, we propose several observational campaigns, spanning a variety of seasonal conditions, using combined passive optical and incoherent scatter radar instrumentation. ...

... Saturation is the primary concern when observing bright targets. The analog-to-digital converter will run out of bit codes at ~28,000 e- pixel-1 in the ATD-GAIN=7 (default) setting, and at ~53,000 e- pixel-1 in the ATD-GAIN=15 setting. ... Hence ATD-GAIN=15 is recommended for targets approaching 28,000 e- pixel-1. ... For example, stars as bright as V~4.4 can be observed without saturation in F502N using the PC at ATD-GAIN=15 with a 0.11s exposure time. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

Meteors are more than just pretty lights in the sky. Since the majority of meteor-producing meteoroids originate from comets, they contain invaluable information about these objects not otherwise obtainable. ... One such possibility is the planet Mars. ... Taking into account the slower average speed of incoming material at the heliocentric distance of Mars from the Sun, a meteoroid of the same mass entering the martian atmosphere at 30km/sec would produce a meteor +0.5 mag fainter than at Earth. ...
