Early Results from STEREO SECCHI COR1
Abstract
With the successful launch and commissioning of STEREO, routine observations of the Sun's corona by the payload began in early 2007. The COR1 internally-occulted coronagraphs, which are classically-designed Lyot instruments covering 1.4-4.0 Rsun, are performing extremely well. More than two dozen coronal mass ejections (CMEs) were detected by COR1 in the first month of observations. As the STEREO spacecraft separate away from Earth, the MK4 coronameter at MLSO will provide a third vantage point for observations of the low corona. In this presentation we will show CME observations from COR1 and MK4, and we will describe the context of these new observations.
