Observing Occultations While Sheltering in Place Suggestions Use prepoint line to locate accessible spots where the target will be visible If the location is very public, have an assistant ready to answer curious people who want to ask what you are doing Examples Sidewalk Driveway Under a streetlight Through an open upstairs window Anyplace safely accessible with with a view of the event
Sidewalk Observing 1 Successfully timed lunar occultations by a gibbous Moon, 7/4/2020. Scope is an elderly C8 given to us by Wayne Warren when he moved to Florida. Streetlight
Sidewalk Observing 2 Skywatcher 16 + QHY 174 GPS camera from various locations on the sidewalk recording occultations by Kalypso 7/3/2020 (miss) Picka 6/1/2020 (miss) 2013 LU28 6/2/2020 (miss) Tsiphone 7/2/2020 failed From the Tsiphone attempt, a mag 13.8 star + a 13.7 asteroid observed from underneath a streetlight. We failed to find the target on time, but the star + asteroid was detectable on the recording (albeit not easily). The arrow points to the pair after the predicted event time.
Lunar Occultations from a Window Observing from a bedroom window on 5/31/2020 But a cloud obscured the occultation of nu Virginis by the Moon
