My 3rd Chumro is that I shall spend a few days in the Southern Hemisphere this coming weekend, so that I can really feel the full impact of the tragedies of Assoro b’Teves by fasting at the summer solstice.
There’s nothing stopping you from staying here (or wherever you are) and just fasting a few extra hours.
Of course, the *real* chumra would be to travel to the South Pole and then fast until sunset — in late March.
