When are stimulus checks going to arrive? And when should Longmont Day be?

-

Dear Johnnie: The stimulus payment has been sent to those who have direct deposit already. Do you know when the rest of us will receive our stimulus payment by mail? — Waiting Dear Waiting: I don’t. But the IRS does.

If you have online access, go to https://www.irs.gov/ coronaviru­s/get-my-payment. There, click on “Get My Payment.” Fill out the online form — including Social Security number, birth date and address — and you can learn when your payment was/will be sent.

The first batch of 2021 payments was sent March 12. The most recent batch was released April 7. The IRS says that payments to non-filer VA beneficiar­ies will be disbursed April 14. Waiting, I trust that your payment will arrive soon, if it hasn’t arrived already.

Speaking of the IRS, the deadline for filing taxes and paying federal income taxes is now May 17.

Dear Readers: That wasn’t much of a column for your money, so here’s a column I’ve run before that relates to a special occurrence that happens ever y year on or about April 15. And I’m not talking about tax day. This column was published originally in 2005.

Dear Johnnie: I think there should be two days each year that Longmont residents celebrate “Longmont Day,” but I don’t know the two dates. These days are scientific­ally predictabl­e. Can you find a scientist to identify them for us? They should be the days — one in the spring, one in the fall — that the sun sets directly behind Longs Peak as viewed from the intersecti­on of Main Street and Mountain View Avenue. Even if these don’t end up being celebratio­n days recognized by the city, I’m sure many would find it interestin­g to note these dates for celestial obser vation. — Dave Miller

Dear Dave: Many thanks to Keith Gleason, the manager of the SommersBau­sch Observator­y, Department of Astrophysi­cal and Planetar y Sciences, University of Colorado ( cosmos.colorado.edu/sbo), for the answer to this intriguing question. I asked Gleason to let us in on his calculatio­ns.

Gleason says: “We want to ascer tain those dates for which the sun can be seen 3 degrees, 25 minutes above the horizon, while simultaneo­usly at an azimuth bearing of 180 degrees, 16 minutes, all from the vantage point of a person standing at the previously determined latitude and longitude of the intersecti­on of Mountain View and Main in Longmont.

“And now to the astronomy part of the problem! Here is where we get to ‘cheat’: Put away the calculator and pen and pencil, and drag up our old reliable, tried-and-true Answer Machine — the Voyager II planetariu­m program from Carina Software.

“After keyboardin­g myself to be standing in the middle of the street in Longmont, I fixed my electronic gaze at the precise calculated direction of Longs Peak, and let time run its course, waiting for the sun to traipse nearby.

“After a few minutes’ worth of taking temporal trips several years into the past and back to the future, one watches the sun (at a fixed time of day) describe a figure-eight pattern in the sky known as the ‘analemma’ — the top and bottom of the ‘8’ being the northernmo­st and southernmo­st annual excursions of the sun (summer and winter solstices, respective­ly); the width of the ‘8’ reflects the ‘equation of time’ where the sun runs fast or slow compared to the time on our watches because of effects of the earth’s axis tilt and its orbital eccentrici­ty.

“Or, on any given day, one can watch the sun appear to slide downward and northward towards the horizon, to finally set in the west (combining the ef fects of ear th’s tilted axis and its daily rotation).

“And then one can isolate the two moments in time each year that are the ones being sought: In the spring, the sun center will be most closely aligned with the tip of Longs Peak at approximat­ely 7:16 p.m. MDT April 15, and in late summer, the sun will again line up with the peak at 7:18 p.m. Aug. 26.

These times and dates may change by as much as one day (for ward or backward) or one minute (earlier or later) because of the ef fects of a leap year; the sun doesn’t exactly repeat itself from one year to the next. But the changing date doesn’t really matter too much, because the half-degree-diameter sun appears — at the distance of Longs Peak — to span a diameter of more than 1,200 feet. Thus, if the sun misses Longs Peak slightly too far to the south on April 15 of a particular year, for instance, one can always walk northward a block or two to make it hit ‘dead on’ on that date. Without a doubt, I’m positive that someone walking up and down Main Street between Ninth Avenue and 17th Avenue will always be able to see the sun set behind Longs Peak on April 15 and Aug. 26 — provided, of course, that the sky is clear and there actually is a good view of the mountain!”

Wow. Thanks, Keith, for the work — not to mention the education — that went into that answer.
