Optimal day to observe flares from geostationary satellites! Geostationary satellites are usually very dim objects, comparable with Pluto. Today, some can get so bright for some minutes, that they can be seen with the unaided eye. Look for them at the optimal coordinates and time given below and with patience. The satellites will move slowly through the stellar field, about one or one cluster every 5 minutes.
And the Geostationary satellites get totally eclipsed tonight. They disappear completely in the shadow of earth at about the same spot on the celestial sphere one after the other, about one satellite or cluster every 5 minutes. With a little patience this can be easily observed through a smaller telescope.
# Umbral shadow eclipse: Satellites disappear at RA=10h43m Dec=-7.1° and reappear at RA=10h47m Dec=-7.1° Duration=4.3 minutes
# Optimal coordinates to look for geostationary satellites: RA=10h31m Dec=-7.1° (Penumbra eclipse begin) The sun is at Dec=-8.4°
# Optimal time to observe geostationary satellites is from 19h 05m to 21h 40m and from 2h 05m to 5h 58m, but observeration of geostationary satellites is still possible during the rest of the night at the eclipse entry/exit points given above.
