Original Post Information
SSTV: Planned Events
Continuing the ARISS Operations SSTV discussion from the ARISS Discord
The ARISS team plans two short SSTV activations in October 2025, each running from Friday to Monday with a 30-minute pause on Saturday for a student contact:
October 3 – 6, 2025: Celebrates the 1957 launch of the first artificial Earth satellite. SSTV pauses on October 4 for a student voice contact.
October 17-20, 2025: Coincides with the International Scouting Jamboree on the Air (JOTA), with Scouting-themed SSTV images. SSTV pauses on October 18 for a student contact.
Participants who receive and submit at least one SSTV image to the gallery can earn electronic award diplomas.
SSTV: Rotation Options
The ARISS Operations SSTV discussion from the ARISS Discord talks about shorter events
For short SSTV campaigns, ARISS seeks input via Discord for image transmission options due to software requiring 12 image files (see this post for further details: https://bsky.app/profile/arissintl.bsky.social/post/3lxfwzqimfc2t).
Option 1: Four unique images, repeated three times (1, 2, 3, 4, 1, 2,, 3, 4, 1, 2, 3, 4).
Option 2: Six unique images, repeated twice (1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6)
Option 3: Tweleve unique images, as in past campaigns.
Option 4: Other suggestions
Join in the ARISS Discord discussion to vote on options and share your thoughts.

Table of ISS Passes
Address: Novers Park Community Association, Rear of 124 Novers Park Road, Bristol, BS4 1RN
- Latitude (degrees N-S where North is +ve): 51.425358°
- Longitude (degrees E-W where East is +ve): -2.593782°
- IARU (Maidenhead) Locator [Calculated by Spreadsheet]: IO81qk
- Elevation (metres above Ordnance Datum [AOD]): 64m
- What.Three.Words: ///Herb.Status.Clips
AOD: In the UK Ordnance Datum is the mean sea level at Newlyn in Cornwall, elsewhere in the world the elevation above sea-level will be sufficiently accurate.

Notes:
In the table below:
- Table Entries with a cyan background indicate passes where: 0° < Maximum Elevation ≤ 30°
- Table Entries with a yellow background indicate passes where: 30° < Maximum Elevation ≤ 60°
- Table Entries with a green background indicate passes where: 60° < Maximum Elevation ≤ 90°
- Times are UK clock time, that is GMT/UTC during the winter and BST/UTC+1:00 during the summer
- Elevation shows the degrees above the horizon. Zero degrees is the horizon and ninety degrees is directly overhead
- Azimuth represents the direction to the ISS using a traditional 16 cardinal point compass rose

If you want to run your own location specific pass predictions try using:
- The AMSAT On line satellite pass predictions
- The Heavens Above website
The AMSAT site will require either:
- Method 1
- Your 6 character IARU (Maidenhead) locator square (e.g. IO81qk); and
- Your elevation in metres (e.g. 64).
- Method 2
- The absolute (without +ve or -ve sign) value of your Latitude in decimal degrees and selecting North where the original value is positive (greater than 0) or selecting South where the original value is negative (less than 0) (e.g. 51.425358 North);
- The absolute (without +ve or -ve sign) value of your Longitude in decimal degrees and selecting East where the original value is positive (greater than 0) or selecting West where the original value is negative (less than 0) (e.g. 2.593782 West);
- Your elevation in metres (e.g. 64).
The Heavens Above site is more flexible and will accept any of:
- Method 1
- Your address including postcode (e.g. Novers Park Community Association, Rear of 124 Novers Park Road, Bristol, BS4 1RN); and
- Your elevation in metres (e.g. 64).
- Method 2
- Your What.Three.Words location descriptor (e.g. ///herb.status.clips); and
- Your elevation in metres (e.g. 64).
- Method 3
- Your Latitude in decimal degrees where +ve is north of the equator and -ve is south of the equator (e.g. 51.425358);
- Your Longitude in decimal degrees where +ve is east of the Greenwich Meridian and -ve is west of the Greenwich Meridian (e.g. -2.593782); and
- Your elevation in metres (e.g. 64).
When using Heavens Above don’t forget to check that you have the correct timezone (e.g. (GMT +0:00) United Kingdom/Ireland)
Heavens Above understands British Summer Time and corrects accordingly
