Member Star Watches for 2019
West Jersey Astronomical Society  Last updated 12.22.2019


These Member Star Watches will also be open to the general public for observing, but unlike the Public Star Watches, members may be preoccupied with their own personal observing (although most amateur astronomers enjoy sharing views of the heavens at any time). Note that Atsion Field is not available for observing at will – a designated club representative must be present according to our permit with the State. There will be other observing sessions of opportunity at Atsion throughout the year, depending on the weather, the moon and celestial phenomena. Because they're weather dependent, they will be scheduled on short notice.


For more information, members should contact Bernie Hosko. Note: To thwart spam, you'll need to manually insert the "@" and the "." (dot) symbols in the address!


2019 Member Star Watch Schedule, Atsion Field

All dates are Saturdays (except Jan 20 = Sunday) at current local time (January, February, November and December are EST, the rest are EDT). The end of Astronomical Twilight is listed. The go/no-go weather calls will be posted to the club's e-groups and to the WAS Home Page. Note: The July Member Star Watch will be incorporated into the club picnic at Camp Ockanickon.
