Targets of Opportunity

The AAVSO International High Energy Network actively observes various targets at the request of professional astronomers. Usually, but not always, this request is to establish visual data to be correlated with observations from space-based satellites.

Usually such requests are distributed via the Alert Notice and/or CCD Views. Here is a list of some high energy projects professionals have asked us to participate in since 2002.

• CCD Views #313: HST UV observations of CVs, Chandra observation of U Gem, and GTN observations of Mark 421
• Alert Notice #290: XMM Newton observations of CV's - including polars
• CCD Views Oct 2002: RXTE Monitoring of WW Cet
• CCD Views May 2002: XMM Newton observing of SU UMa and EI UMa
• CCD Views March 2002: Monitoring of GK per by RXTE, XMM, and Chandra
• Alert Notice #277: Observations of SS Cyg with Chandra, EUVE & RXTE
