Friday 13th today, but did not spot any black cats, overhanging ladders or other ill omens. I lived with a black cat for 15 years, so I don't think they do me harm.
It was a nice bright day, although it continues to feel cold. Mercury at 8C / 46F. I keep getting notifications that the aurora could be on, but it will soon become impossible to see the aurora from my latitude, 58 North. The nights are getting shorter and shorter, meaning that the aurora will be invisible.
Today, I found out that two of my contacts had their email addresses hacked. It is important to regularly change passwords, and choose a password that is not easily guessable. Picking a word from a dictionary is a bad idea though; better combine letters, numerals and codes (such as %, ^ or &).
