Salem State University is closed today in celebration of the Patriots' Day Holiday. Therefore, Collins Observatory will also be closed this evening, Monday, April 21, 2025, regardless of the sky, which is predicted to cloud over. We will reopen next Monday, April 28, 2025, weather permitting. Note: Monday, May 5, 2025 will be the last public observing night until September.

Note: Collins Observatory is open to all SSU students, faculty, staff, and non SSU individuals. Masks are no longer required in the observatory.

Please check back on this site for any changes and updates about openings, or any COVID-19, or other safety protocols in the future.

Collins Observatory is normally open on CLEAR, or MOSTLY CLEAR Mondays from 7-10 PM, or later depending upon the time of sunset. We’re open during the school year from September to the beginning of May, and are closed on school holidays, when the school is on vacation, mandated closings, and during the summer. It is also available for special group visits during the year when feasible.

The observatory houses a Meade 12-inch LX-200 ACF telescope, which does fairly well in the light polluted sky over Salem.

Please call the observatory at 978-542-6452, if you’re coming from a distance, as the weather is a bit unstable this close to the ocean.

Notes:

What’s up tonight?

Mars is in the southwestern sky (in Gemini) as it gets dark this week. It appears pretty small now, but is still viewable through a telescope.
Jupiter is in the western sky (in Taurus) as it gets dark this week. Its apparent size has shrunken noticeably now, and its brightness has dimmed, but it still looks great through a telescope eyepiece.
Uranus is pretty well lost in the twilight of the western sky (in Taurus) this week. So it will not be visible any longer this season.
M42, in the constellation of Orion, is still in the west/southwestern sky as it gets dark, but is rapidly moving towards the western twilight. It will be lost in the twilight by the end of the month.
The constellation Leo is up in the southeastern sky as it gets dark this week, while Virgo trails it in the east/southeastern sky as it gets dark, and is fully up by 09:00 PM this week. Both of the constellations bring a wealth of galaxies with them (weather and Moon permitting).
