Noctilucent clouds visible between clouds - 11.8.2022 at 03.10 - 11.8.2022 at 03.25 Helsinki Observation number 108293

Visibility III / V

When the observation window after three was still open from the right edge, some gaps and thinnings appeared in the lower clouds. Fortunately, the openings moved quite quickly. The slanted ridge in the northeast of the main photo visually stood out from the mountain due to its shape, so I snapped a total of 20 photos from that direction. With exposure times of three and four seconds, the faster moving clouds blurred, but the streaks remained sharper. The white balance setting 3773 K compensates for the brown color. The lower clouds were in many layers and of many shapes. Even the cloud holes were not clear holes in the cloud boards. At least a few stars stand out in the main picture in the direction of the Driver and Gemini.
