Modified counter: Spring 2025
The legend reads 3/28/2025; the poster’s flight table reads 3/29/2025. It marks 87,885 ft burst and profile maxima near 63,000 ft. Horizontal: elapsed hours. Vertical: CPM.

External temperature versus altitude
The original profile is preserved. Narrative rounds the minimum to about −60 °C; the plotted curve extends below −60 °C. No precise minimum is inferred by digitizing the image.

UVA relative intensity versus altitude
Horizontal: altitude in feet. Vertical: relative intensity. The broad range at each altitude is preserved, rather than replaced by a smooth trend. UVA uses its own intensity scale; these values are not established here as calibrated irradiance.

UVB relative intensity versus altitude
Horizontal: altitude in feet. Vertical: relative intensity. Read the UVB scale separately from UVA: a taller plotted trace is not automatically a larger physical irradiance when the axes use different ranges.

UVC relative intensity versus altitude
Horizontal: altitude in feet. Vertical: relative intensity. UVC uses its own scale. This is the recorded channel response, not independently calibrated ambient UVC exposure; sensor spectral response and calibration must be checked before making that claim.

Student neutron-detection concept
Published schematic of the team’s modified-counter experiment. Counts are not calibrated neutron-only flux or dose, and this diagram does not quantitatively establish shielding performance.

- The Fall 2024 and Spring 2025 documents contain the same seven images. Only the plot dated November 23, 2024 is assigned to Fall 2024.
- Spring 2025 plot legend and poster flight table disagree by one day; no exact launch date is asserted here.
- Causal explanations in source prose remain hypotheses, separate from measured profiles.
Source: team-supplied “Spring 2025 launch acquired data” report and photographed presentation boards. Student research, not independent instrument certification. Detector counts are not dose; channel output is not automatically calibrated concentration or irradiance.
