There are several feature finding modules being developed. Mouse over some of the pictures for bigger images and links for some of the modules. Below is a full list of modules.
Active Region module SPoCA The Spatial Possibilistic Clustering Algorithm (SPoCA) has been implemented to deliver modules detecting Active Regions (ARs) and Coronal Holes (CH) SDO FFT Active region detection module video The Spatial Possibilistic Clustering Algorithm (SPoCA) has been implemented to deliver modules detecting Active Regions (ARs) and Coronal Holes (CHs).
Bright Point Finder module SDO FFT Bright point detection module video (Saar, Farid): This module detects EUV Bright Points from AIA images, and measures location, outline, size, and brightness. The figure shows detections in slight excess brightness, overlaid on the original AIA 193 ̊A image.
CME detection module SDO FFT CME detection module (CME finder) video 1 SDO FFT CME detection module (CME finder) video 2 The module builds on current efforts to establish a new automated multi-scale CME detection and tracking algorithm. The Normalising Radial-Graded Filter (NRGF) is applied to images to remove the steep gradient in coronal …
Dimming Region Detection Module Coronal Dimmings Detector: Detects, tracks, and categorizes coronal dimmings and provides space weather alerts. The AIA 193 ̊A image from February 2nd 2011 shows an inset dimming region.
Coronal Hole Detection Module SPoCA SDO FFT Coronal Hole detection module video The Spatial Possibilistic Clustering Algorithm (SPoCA) has been implemented to deliver modules detecting Active Regions (ARs) and Coronal Holes (CHs).
“EIT” (EUV) Wave detection module (CORPita) SDO FFT “EIT” (EUV) Wave detection module video (Long): The EIT wave module (CORPita) is triggered by the flare module and uses AIA 193 ̊A difference images to identify and track propagating wave fronts as they emanate from the flare site. The module then determines and records the location, …
The Advanced Automated Filament Detection and Characterization Code (AAFDCC) module was deployed on March 30, 2010 and is currently running on the SDO-FFT cluster at SAO. The AAFDCC (Bernasconi) provides automated tracking of the origin, evolution, and disappearance (eruption) of all Hα filaments. Outlines contours, determines chirality, tracks individual filaments, handles mergers and splitting.
Flare Detective module Stewardship of the Flare Detective Module was passed from Paolo Grigis to Henry Winter and Paola Testa at SAO. This module rebins image in macro-pixels and analyzes light curves in parallel. AIA 193 ̊A image, May 5th 2010. Produces flare alerts, flare class, light curves, DEMs, quicktime movies.
SWAMIS emerging flux detection module movie SWAMIS (Lamb, DeForest): Identifies all magnetic features on the Sun, their origin and demise, from HMI magnetograms. Swamis provides alerts for emerging flux. The white box in background image highlights the zoomed in area, which shows the poles of a detected emerging flux region as it grows for eight …
(Savcheva): The code is designed to detect and measure jets in Coronal Holes. The AIA 193 ̊A figure shows that in its current state of development the jets are clearly brought out by edge enhancement techniques.
Non-Linear Force-Free Field Extrapolations (NLFFF; Wiegelmann): Shown are AIA images of AR11158, observed 2011-02- 14T20:34:00.34. Overplotted are the NLFFF extrapolated magnetic field lines extrapolated from an SDO/HMI vector-magnetogram.
(McAteer, Calabro, Pevtsov): This module measures the strength, period, and duration of oscillatory motions in any of the AIA channels using a wavelet technique. The module can be triggered by any event registered by other modules, such as flares, filament eruptions, CMEs, and jets. Shown is a 120 x120 arcsec window with areas of 3 …
Polarity Inversion Line detection module SDO FFT polarity inversion line (PIL) detection module movie (Engell): This module finds and draws PILs from HMI magnetograms. The yellow lines represent the PILs. Red boxes delineate Active Regions. PILs with very large horizontal field gradients, prone to flaring, are drawn in red. The green is high gradient associated …
SDO FFT Sigmoid sniffer module movie Sigmoid Sniffer (Georgoulis, Raouafi): Automatically detects and outlines X-ray sigmoids in the solar corona, determining their chirality (direct [S] or inverse [Z] sigmoids), aspect ratio, heliographic location, and host solar active region, if any. Operates in 94 ̊A (example shown) and 131 ̊A AIA images. The square encloses a …
(Zharkova, Zharkov): Detection and tracking of sunspots, and measurement of their outline from HMI images in Fe I at 6173 ̊A. Red delineates the umbra, blue the penumbra.
Trainable Module Trainable, multi-purpose detection module (Angryk, Banda, Martens, Schuh): This module can be trained by example to detect any type of solar event or phenomenon. The figure above shows a full-disk Hα image segmented into grid-based cells, with training examples on the left and detected events on the right. The cells in the left …
