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

Notes:

Compass Rose English North

In the table below:

  1. Table Entries with a cyan background indicate passes where: 0° < Maximum Elevation ≤ 30°
  2. Table Entries with a yellow background indicate passes where: 30° < Maximum Elevation ≤ 60°
  3. Table Entries with a green background indicate passes where: 60° < Maximum Elevation ≤ 90°
  4. Times are UK clock time, that is GMT/UTC during the winter and BST/UTC+1:00 during the summer
  5. Elevation shows the degrees above the horizon. Zero degrees is the horizon and ninety degrees is directly overhead
  6. 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 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. ///hugs.sorry.dime); 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
