Radio JOVE 2023 Solar Eclipse Citizen Science Observation Instructions

2023 Annular Solar Eclipse - Saturday, October 14, 2023

Radio JOVE is a worldwide community. We recognize that these solar eclipse events happen over the Americas, but anyone is welcome to participate and learn.

Instructions for Observations

A. General Information for the 2023 Annualar Solar Eclipse, October 14, 2023

Begin Observations 15:00 UTC (11:00 EDT)
Maximum eclipse is 18:00 UTC (14:00 EDT)
End Observations 21:00 UTC (17:00 EDT)

Because the annular eclipse lasts about 4 hours, we want to observe about 6 hours total to get data before/after the begin/end time of the eclipse. We want observations within three hours of the maximum eclipse (i.e. +/- 3 hours of 18:00 UTC on 14 October 2023)

Here is excellent timing information for any location:

B. Radio Telescope Setup and Observation

  1. Use Radio JOVE 1.1 receivers or Radio JOVE 2.0 SDRplay radios.
  2. Use a single or a dual dipole antenna.
    1. Dual dipole antennas - E-W orientation of the wires is recommended; remove the phasing cable so the antenna beam is pointed at the zenith.
    2. Single dipole - an E-W orientation is recommended.
  3. Verify the computer clock is set to UTC time (i.e., Time Zone UTC under adjust date/time settings)
  4. Update your Metadata in your Radio-Skypipe or Radio-Sky Spectrograph software.
  5. Calibrate your radio telescope if you have a calibrator*. It is best to calibrate at the start and end of your observations.
    *Most people using the Radio JOVE 2.0 telescope do not have a calibrator; thus, it is okay if your data are not calibrated. Plans for a calibrator are coming soon. Those using the original RJ1.1 single frequency receiver with an RF2080 calibrator are highly encouraged to contribute their data.
  6. If possible, observe from about 15:00 - 21:00 UTC for several days before and after the date of the eclipse. Make notes about solar activity, observing conditions, radio frequency interference (RFI), or local storms (**Please disconnect your antenna during any local thunderstorms**). Keep these data files for later comparison, if needed.

C. Data Analysis and Data Archiving

See this Video to help you with archiving your data:

  1. Data Analysis
    1. Use Radio-Sky Spectrograph (RSS) software to load and display your data file. Click the icon in RSS to manually enter the start/end times of interest. For example, data from July 28, 15:00 - 21:00 UTC is shown in Figure 1.
    2. Determine and identify whether any solar radio burst activity was received. For example, Figure 2 shows solar bursts from about 15:40 - 16:10 UTC on July 28.
    3. Save data into files of less than a 2-hour duration (needed because of the file size limitation of the data archive).
      1. Click the RSS icon to Save the visible portion of the spectrograph as a ".sps" data file (Figure 3). For example, I saved a 30-minute data file.
      2. Click the Camera icon (Figure 3) to save an image file of your data (jpeg, png, etc.).
  2. Data Archiving
    1. Reminder: you must request a Data Submitter Account to upload data files. See instructions on the data archive:
    2. The current maximum file size for uploading is 64 MB. This is about 2 hours of data from the Radio JOVE 2.0 telescope.
    3. Upload your image file and data file to the data archive:
      IMPORTANT: Please upload three 2-hour data files for October 14, 2023, 15:00-17:00 UT, 17:00-19:00 UT, and 19:00-21:00 UT even if you do not get solar bursts. These files can be used to compare data from different sites.
