|---|---|---|---|---|---|---|---|---|---|
| MORP #441 [1] | 24.7 | 0.969 | 159.7 | 48.7 | 61 | 70.3 | 13; 20 [4] | −4.04 | −0.78 |

| Alberta fireball [4] | 104 | 0.994 | 121.4 | 207 | 46.5 | 62.1 | 1800 | −4.49 | −0.46 |
| FH1 [5] | – | 1.07 | 177.18 | – | 112.6 | 73.7 | 187 | −4.173 | – |
Notes. More recent mass estimates result from using modern luminous efficiency of Borovička et al. (2020). For the hyperbolic meteor FH1, some orbital elements are not defined. [1] Halliday et al. (1996); [2] Spurný & Borovička (1999a); [3] Spurný & Borovička (1999b); [4] Vida et al. (2023); [5] Peña-Asensio et al. (2024).
