Session Aims & Highlights (2024-09-15)

Main aims

  1. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions.
  2. ImageLink/TheSky6.  Monitor session for any further incidents of the issue where the ImageLink process freezes for 5 minutes leading to Target Abort & Session Suspension.

Fig 2.   5 days chart comparing Weather Station's Outdoor Temperature (white line) & Zigbee Outdoor Temperature (orange line)

Data confirms that Weather Station's Outdoor Temperature and Zigbee's Outdoor Temperature are in generally good agreement at night and on cloudy days.  The Weather Station sensor reads higher during warmer/sunny daytime periods. The difference is believed to be due to subtle difference in sensor position.

Image
 

Fig 3.   5 days chart comparing Weather Station's Outdoor Humidity (white line) & Zigbee Outdoor Humidity (orange line)

Data confirms that Weather Station's Outdoor Humidity and Zigbee's Outdoor Humidity generally track each other.  The Weather Station sensor reads higher humidity during nighttime & on cloudy days, but reads lower humidity during warmer/sunny daytime periods (when temperature is warmer).
