AAVSO ALERT NOTICE 283 (May 21, 2001)

RARE SUPEROUTBURST OF 1227+14 AL COMAE BERENICES

Alert Notice 379: Support for Spitzer observations of tremendous outburst amplitude dwarf novae (TOADs)

May 16, 2008 : Dr. Steve Howell (NOAO) requests monitoring of a subset of the known and suspected tremendous outburst amplitude dwarf novae (TOADs) in support of Spitzer Space Telescope observations of these objects. Observers are asked to increase their monitoring of the objects in the table below in support of this campaign.  We note that several of these objects -- notably the WZ Sge stars WZ Sge, GW Lib, and V455 And -- are not expected to superoutburst during the next year, but observations are still encouraged in case they exhibit unexpected behavior.
