Phases of the moon for April are:
• April 3: Last quarter.
• April 10: New moon.
• April 18: First quarter.
• April 25: Full moon (Egg Moon, Grass Moon, Easter Moon, Paschal Moon).
On the first Wednesday evening of the month, after dark and weather permitting, the Northern Oklahoma College observatory will participate in a series of research programs with observatories around the world to provide measurements for the Hubble Space Telescope research program.
Anyone in the Enid community is welcome to participate. Those participating will conduct observations and measure light outputs from selected stars to determine how these stars change their brightness over time. This data will contributed to the international professional astronomy research community.
The Northern Oklahoma College Mackie Planetarium will be open to the public at 7 p.m. the first Thursday of each month.
Admission is free, but a donation of a canned good or non-perishable food item for Horn of Plenty’s pantry would be appreciated.
The program for April is “Birth of the Solar System,” followed by a program about Enid’s spring night sky.
Weather permitting, the observatory will be open for viewing objects in the night sky.
Every Wednesday and Thursday, weather permitting, the observatory will be open to the public. Sessions start at 8 p.m. Large groups planning to visit the observatory or planetarium should call 548-2399 to schedule an appointment.
Killam is resident astronomer and astronomical league coordinator for Leonardo’s Star Quest Astronomy Club and director of the NOC observatory.
