Date published or finalized for release: 2023-09-25 4. Date of data collection (single date, range, approximate date): 2011-01-01 to 2016-12-31 5. Information about funding sources that supported the collection of the data: NASA HGI grant 80NSSC20K0718 NSF CAREER grant AGS1752268 6. Overview of the data (abstract): This database constitutes the first release of data from the Solar Jet Hunter project. Solar Jet Hunter is a Zooniverse-based citizen science project that has, since 2021, enlisted volunteers from the general public to help identify extreme ultraviolet jets of plasma in the Sun's corona. These jets release magnetic energy at the Sun and enable streams of plasma and energetic particles to escape to the solar system, but the origins of and mechanisms underlying these jets are still not understood. In Solar Jet Hunter, videos of possible jets are presented to volunteers, who are asked to identify whether a jet is present, and if so, its start time, end time, and base location. Volunteers also box the jet, providing information on its shape and height over time. The results from many volunteers are then aggregated into consensus results for each potential jet in the study. Those results are listed in this data set. The data presented to volunteers is from the Solar Dynamic Observatory / Atmospheric Imaging Assembly instrument, specifically the 304 angstrom filter, and all of the candidate jets were identified as possible jets in the Heliophysics Event Knowledgebase (HEK). The data set included here lists Solar Jet Hunter results from the years 2011 through 2016. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Relationship between files: The list of resulting jets is stored in both a JSON and a CSV format.  The .json has extra information from the aggregation, but the .csv file is enough to provide the overall properties of the solar jets for easy access for science analysis.   -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Citizen Data collection using Zooniverse: In Solar Jet Hunter, videos of possible jets are presented to volunteers, who are asked to identify whether a jet is present, and if so, its start time, end time, and base location. Volunteers also box the jet, providing information on its shape and height over time. 2. Describe any quality-assurance procedures performed on the data: The results from many volunteers are aggregated into consensus results for each potential jet in the study. 3. Instrument for data collection: Solar Dynamic Observatory / Atmospheric Imaging Assembly instrument, specifically the 304 angstrom filter and Zooniverse. ------------------------------------------------------------------------------------------------------ DATA-SPECIFIC INFORMATION FOR: Jet_clusters_3.0_2.0_paperID.csv and Jet_clusters_3.0_2.0_paperID.json ------------------------------------------------------------------------------------------------------ Both files contain the following information: "sjh_ID”: Solar Jet Hunter ID for this jet (data and hour of event; last number denotes which event this was in that hour) Date: Observation time of the start of the jet (format YYYY-MM-DDThh:mm:ss) SOL_event: The coronal jet event name from HEK database where this jet was found in (multiple jets can be found in one coronal event) Duration of the jet: (minutes) Basepoint_X: Basepoint of the jet in (Heliocentric solar X coordinates in arcsec) Std_X: Standard deviation of the base point if there were multiple measurements of the base point (Heliocentric solar X coordinates in arcsec) Basepoint_Y: Basepoint of the jet in (Heliocentric solar Y coordinates in arcsec) Std_Y: Standard deviation of the base point if there were multiple measurements of the base point (Heliocentric solar Y coordinates in arcsec) "std_X" "std_Y" and "std_width" occasionally include 0 = this is because the jet was found in only one subject (and so we only have one measurement of each of these values) basepoint_X_longitude: Basepoint of the jet (longitude) basepoint_Y_latitude: Basepoint of the jet (latitude) max_height: Maximum height jet reaches (arcsec) upper_H: Upper limit of the error height (arcsec) lower_H: Lower limit of the error height (arcsec) avg_width: Average width of the jet box (arcsec) std_width: Standard deviation width (arcsec) velocity: Velocity estimate (arcsec per sec) sigma: Average sigma of the jet, (sigma= 1-IoU) flag: Binary quality flags. flag 100 means the jet cluster has a duration of less than 6 minutes, which for many corresponds to a jet cluster found in one Zooniverse subject. flag 010 means the velocity estimate could not be calculated because the maximum was reached in the first subject the jet was found in. flag 001 means the basepoint has a Longitude of higher than 90 degrees meaning the base point was found to be (slightly) off limb. The flag value gives the sum of the flags. 110 means both the first and second flags are high. The .json has all these properties, as well as properties on the individual subjects that compose each jet:   "subject”: Zooniverse subject ID "sigma”: 1- IoU, the IoU is the intersection over union of all the boxes drawn by the volunteers "time": start time of this jet subject "solar_H": height of this subject in arc seconds "solar_H_std": "upper": upper limit error bar on this estimate. "lower": lower limit error bar on this estimate "solar_W": width of this subject in arcseconds "solar_start": "x": x coordinate of the base at the start in arcseconds. "y": y coordinate of the base at the start in arcseconds "solar_end": "x": x coordinate of the base at the end in arcseconds. "y": y coordinate of the base at the end in arcseconds "start": "x": x coordinate of the base at the start in pixels. "y": y coordinate of the base at the start in pixels "end": "x": x coordinate of the base at the end in pixels. "y": y coordinate of the base at the end in pixels "cluster_values": "x": average x coordinate of the jet base in pixels. "y": average y coordinate of the jet base in pixels. "h": height of the jet in pixels. "w": width of the base in pixels. "a”: Angle of the box with reference to the left lower corner
