Observations of dwarf novae requested
Active Dates: Feb. 24, 1997 – Feb. 26, 1997
Abstract:
Astronomers at Keele University, England, will be observing dwarf novae in outburst with the 4-meter William Herschel Telescope between February 24 and 26 in order to obtain spectroscopy. They have requested our assistance in monitoring dwarf novae, and in particular the dwarf novae listed below, in order to know which systems are in outburst at the time of their observations.
Justification:
Your assistance will be crucial to the success of this observing run. Please monitor these and other dwarf novae closely until the end of February and report your observations to AAVSO Headquarters daily by email, fax, or telephone so we may inform the astronomers.
