2I/2019 Q4 (Borisov)

Post by Christopher K. »

This interstellar object is out of range for most Baton Rouge amateurs due to its mag 18 dimness. It is not listed in The Starry Night Pro Plus; all I can say is that for the next few nighttime periods it will be near mag 4.0 A-class Gamma Crateris, which reaches thirty degrees in the Baton Rouge sky Monday at 3:51am CST.

Here is the NOAA forecast for 4am Monday...
precipitation potential, 0%
sky cover, 67%
relative humidity, 96%
temperature, 13˚C
surface wind, S 3 km/h

The Hubble team is planning to broadcast live shots of the interstellar visitor Friday at 5am CST on NASA's Media Channel. Its closest approach to the Sun was on Saturday.
