Charlie, Kin, and I met up at 34th and Park for the second Manhattan-henge event of the year. Charlie had found two dates: 11 July from American Museum of Natural History and 12 July from Astronomy Picture of the Day (APOD). From the looks of this evening's turn out and that the Sun did not set between the buildings/street probably means that folks will turn out for it tonight on 12 July 2006. The hazy sky did not help but I thought that if the Sun did creep into that less-than-two-degree-corridor-between-the-buildings that it would be strong enough to punch through that crud. In fact, the haze could be a benefit to attenuate the Sun's brilliance for sharper photos and brief naked eye views.
Back on 28 May, the last Henge event, the Sun set around azimuth 298°32'. This value was determined by using a value for the Sun's elevation at 0°28', and the angular size of the Sun is approximately 31'34".
On 11 July, at 8:20pm the Sun was 0°29' altitude with an azimuth of 299°09'. The Sun's angular size, according to Planetarium for the Palm, is 31'28".
On 12 July, at 8:20pm the Sun will be 0°25' altitude with an azimuth of 299°02'. The Sun's angular size remains unchanged at 31'28".
Given the azimuth values, the Sun will set slightly North, 30 arc minutes, which is nearly a solar diameter. From my point of view at 34th & Park, the street corridor is slightly less than my forefinger extended at arm's length. A finger width is estimated to be 2°. I haven't calibrated that measurement to be any more exact ;^D but my guess is that the angular measurement of the street to 1° 45'. That measurement yields a street corridor measurement in terms of solar diameters to be ~3 ½.
