==================================================================== ==> time is to be transferred to this proposal from mbarlow_novatoo ==> time is to be transferred to this proposal from rgehrz_proptoo ==================================================================== this proposal requests: 1) an upgrade to priority 1 of 15 hours of priority 2 time allocated in the last review round to the proposal mbarlow_novatoo; and 2) a reallocation of 2865 sec of priority 1 time to this program targeting too galactic novae from time allocated to observe extragalactic novae in the rgehrz_proptoo program. our goals and strategy are to obtain iso spectroscopic observations that will extend our understanding of the physics of the thermonuclear runaway that initiates a nova event and the subsequent temporal evolution of the ejected material. specifically, our proposed iso too initiative seeks to address four research problems in the study of classical nova evolution: 1) chemical abundances of nova ejecta from coronal and forbidden emission line spectroscopy; 2) dynamical studies of nova ejecta; 3) measurements of the density and masses of the ejecta; and 4) determinations of the grain size distribution and mineral composition of nova dust. our iso too initiative includes supplemental, simultaneous, and complementary observations using other ground-based and space-based observatory facilities available to our team. these observations include optical and infrared spectrophotometry using lowell observatory, arc, the wyoming infrared observatory (wiro), the mt. lemmon observatory (mlof), noao, ctio, ukirt, eso, the palomar observatory and the nasa irtf. the frequency of new galactic novae events potentially observable by iso is of order 2 to 4 per year. each object must be measured on at least two separate occasions, since the physical conditions in the ejecta of these novae change dramatically on short time scales.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
