Very Low Tides early next week will provide opportunities for observing sea life in the lower intertidal zones. On Monday, January 11, the tide dips to -1.66 feet at 2:27 p.m. Tuesday’s low tide of -1.78 feet occurs at 3:09 p.m. Wednesday’s low tide of -1.67 feet happens at 3:50 p.m.
Recent Chilly Days and Nights confirm that San Diego’s lowest temperatures (according to more than a century of weather records) tend to occur during the month of January. January’s mean temperature at Lindbergh Field is about 55 degrees Fahrenheit. (July’s mean is a balmy 70 degrees.) To experience much colder temperatures, journey to the Cuyamacas; -1 and -4 degree readings were once recorded there — the two lowest temperatures ever recorded in the county.
Orange Aldebaran shines above Orion on January 7 with the large, loose Hyades cluster in its background. Binoculars are the ideal instrument for this cluster given its size: its brightest stars (4th and 5th magnitude) span an area about 4° wide. (Higher above, the Pleiades are hardly more than 1° across counting just the brightest stars.)
The main Hyades stars famously form a V. It's currently lying on its side. Aldebaran forms the lower tip of the V. With binoculars, follow the lower branch of the V to the right from Aldebaran. The first thing you come to is the House asterism: a pattern of stars like a child's drawing of a house with a peaked roof. The house is currently upright and bent to the right like it got pushed.
