4.2.0

Improves storage of flare predictions based on 4.1.0 feedback.
The flare database introduced here is incompatible with 4.1.0 and updating drops the 4.1.0 flare table.

Release Notes:

• Fixes the typo showing "Solar Flare Predictionss"
• Removes a patch meant to try to "fix" ASSA latitude/longitude positions
• Showing flare prediction source data now includes all data provided by the CCMC API

Maintainer Upgrade Guide:

• After updating the API and App to 4.2.0, you must create the flare prediction database table by executing the SQL in /install/database/2023_04_11_update_flare_table.sql.
  • You do not need to run the 4.1.0 update first
  • If the 4.1.0 table exists, all data will be erased and will need to be re-imported.
• Use /management/events/ccmc/import_predictions.py to retrieve flare predictions for your server. Use -h to see the script's usage information
• Ideally you will run import_predictions.py on a schedule to keep flare predictions up-to-date
• The GSFC servers run the following scheduled command
  import_predictions.py "$(date --date '3 hours ago' -u '+%FT%T')" "$(date --date '+48 hours' -u '+%FT%T')"

4.1.0

Helioviewer 4.1.0 adds feature support for the CCMC Flare Scoreboard.
The flare scoreboard is a database of predictions made by humans and algorithms for prediction when and where a solar flare may occur.
These predictions are now pinned on Helioviewer the same way that actual flares and other solar events are displayed.

Release Notes:

• Stability improvements for creating movies and screenshots
• Patches to data coverage statistics to fix overcounting files
• Update to api status page to show full time range of available data with links to upstream data sources and internal coverage tables.
• Several changes to remove usage of deprecated PHP features.
• Support for CCMC Flare Scoreboard
