== Week 6 (September 23) ==

* Clear weather tonight possible (Monday) and the coming weekend

* Roundtable discussion about project ideas (bring your own) such as
** Jupiter imaging (must be done soon)
** Bright star photometry (examples are some TESS candidates and zeta Andromedae now)
** Use of latest CMOS color sensors for photometry 
** Other TESS candidates (TESS is currently observing the northern sky)
** Variable stars in the TESS public data
** Comets [http://www.aerith.net/comet/weekly/current.html http://www.aerith.net/comet/weekly/current.html]
** Supernovae [http://www.rochesterastronomy.org/supernova.html http://www.rochesterastronomy.org/supernova.html]
** Anything in Orion (visible after midnight now) 
** Geosynchronous (GEO) satellites (where, when, optical variability)
** Low Earth orbit (LEO) satellites (wide field camera, untracked)
** Near-Earth objects 
** Mercury transit on November 11 (with an exoplanet transit at night backup)
** Other selected targets in either hemisphere, your choice

To continue this week and next as time allows
