Pre-Session Weather Forecast (API data from darksky.net)
Pre-Session Weather forecast showed initial rain showers followed by semi-clear skies in first part of evening (42-50% cloud cover), with skies becoming progressively more cloudy (56-76% cloud cobver) with possibility of light rain showers throughout night.
Minimum tempertaure of 3 degC and light-moderate wind (9-13 mph).

In the event skies there were sufficiently clear for observing in first half of night with passing cloud/light rain showers,
But second half of night was mainly cloud with only occassional clear patches
Minumum Temperature of 1 to 2 degC. Winds relatively light, but bringing showers in from the North Sea.

PHD2 Upgrade 2.6.9dev3

The observatory computer's PHD2 application was upgraded to the new 2.6.9dev3 version (dated 02 Jan 2021) today (2021-01-04).  This development snapshot includes two particular fixes for the new multi-star guiding feature.

- Multi-star: correctly report guide star distance to imaging apps
- Multi-star: do not automatically reset the Use MultiStar option in the UI

The later item might fix the query/issue noted during the S844 session where PHD2 Multi-Star Guiding seemed to turn off by itself.

SharpCap Upgrade 3.2.6473.0

The observatory computer's SharpCap application was upgraded to the new 3.2.6473.0 version (dated 03 Jan 2021) today (2021-01-04).  This development snapshot includes a fix for compatibility with ASCOM Platform 6.5SP1, plus some other bug fixes.

Although no problem was noticed when running the previous 3.2.6383.0 version against the ASCOM 6.5SP1 platform in sessions S843 and S844 the use of SharpCap in these sessions was relatively limited and it seems prudent to preempt any possible issues further down the line by installing the latest version.
