Brightening of 0059+53 Nova Cassiopeiae 1995 AND Request to monitor dwarf nova 0103+59 HT Cassiopeiae AND Request to monitor 2138+43 SS Cygni

Active Dates: Nov. 16, 1995 – Nov. 27, 1995


Abstract:

This campaign covers the brightening of Nova Cassiopeiae 1995 (N Cas 95), monitoring the dwarf nova HT Cassiopeiae (HT Cas) during Hubble Space Telescope observations, and monitoring SS Cygni during Japanese ASCA satellite observations.

Justification:

N Cas 95 is brightening and shows features that may classify it differently from classical novae, warranting further observation. HT Cas is being observed by the Hubble Space Telescope, and its state needs to be monitored to interpret HST data accurately. SS Cygni will be observed by the ASCA satellite, and correlation with optical data is needed.
