A software package for 'Novel EIT wave Machine Observing'
On-Disk Eruption Measure Tool


NEMO autonomously detects solar eruptions in image sequences from EIT in real time since 2006. The new generation of various on-disk CME precursors often weak on the level of general background, discovered by the SOHO mission, make high demands on their recognition methods. NEMO consists of a series of high level image processing techniques developed to extract eruptive features from the EUV solar disk under complex solar conditions. This technique is based on the general statistical properties and underlying physics of eruptive on-disk events. More. One of the specific NEMO features is the capability to find in the large family of solar dimmings those connected to CMEs. At present NEMO is mainly focused to extract various "EIT waves" and eruptive dimmings. The detection errors on real-time quick look data introduced by the recently increased noise to signal ratio of the EIT telescope are presently roughly eliminated. Particularly important is NEMO’s capacity is to extract patterns from a noisy background.

Since August 1, 2010 NEMO-1.0 stopped to provide Real-Time Alerts based on EIT wave observations due to the termination of the "CME watch observational programme for SOHO/EIT".
