Last year I remember reading a remark that said it is really not the best time of year to do this sort of thing. Certainly, I did not perceive as much attention to the event. Why was it so poor this year? Some say that the novelty is wearing off. Last year, the city's Earth Hour efforts saved 296 megawatts. and 9:30 p.m., a drop of about 5 per cent, said Jennifer Link, a spokeswoman for Toronto Hydro. In Toronto, energy use fell by 115 megawatts between 8:30 p.m. I transferred a still image over from the camcorder and played with it briefly in Fireworks. I tried pressing LED on CCD camera to turn off the cooling but it didn't move.ġ:07. I inspected the Oregon Scientific weather station: -5.7☌, 43% humidity, the pressure was rising. Tried a 90 second shot but there was lots of trailing. I was pleased that there was very little trailing.ġ2:41 AM.

I did manual exposures at 15, 20, 30, and 60 sec. I just finished imaging M82, with the gain at 50%. I was confused for a moment until I remembered that the new finder scope didn't rotate the field of view.ġ2:23 AM. I star hopped, classic style, to M81 and M82 using the Pocket Sky Atlas. I removed power from the Kiwi to clean up the display. With the 8 second integration, I dialled out the drift. It was actually very interesting having a live video feed. I tried redoing it but I saw, on the screen, I was still drifting. I was a little perturbed by the polar alignment being off. I would still have to examine the video record of course. So I unofficially called it an observed miss. While I monitored the star on the Oslon LCD, I did not see it blink out. I didn't see anything blink out at 22:16:16. I simply reinitialised the Kiwi and it started up fine. And same, for the second time, I had a GPS error. It immediately stopped when I closed the little LCD.ĭouble-checked everything once again. I noted this time that I get the microphone feedback when camcorder display open. The drift error was fairly pronounced so I rotated the flip mirror about 90 deg to take advantage of field width. So, I rewound to beginning and resumed recording. Considered for a moment drumming up another tape but I wasn't exactly sure where I had put them. I had actually briefly wondered where I was on the tape. I had it! Went inside to get the camcorder. I connected control pad (on the fly)! I centred on the star and flipped the mirror. At last, I found and centred on the target star. But I found the tree in the way again.ĩ:49. I knew that I was less than a degree from the target. Still had the Williams Optics mirror attached to the SCT. I had the StellaCam 3 installed in Vixen flip mirror, at the proper depth (to be parfocal) and set it aside. I could start setting up occultation gear. I'd have to wait a bit for the star to clear. Continuing the star hop, I landed on star HD 57902. I put up the light shield, a bit higher this time. There were a lot of tree branches in the way. I could do drift alignment analyses.ĩ:00. I know I'd need a better alignment for long exposures. Did some periodic checks over the next 20 minutes and the alignment seemed OK. I left the 'scope on Sirius to gauge the tracking. Polaris just at edge of roof, from the new tripod position. The SCT adapter was reinstalled to the visual back. The dew heaters were running (including the coffee cup heater on the finder scope). Environment Canada said it was -4.3☌ but it felt way colder than that. I had the power cord through the window.Ĩ:25. I now had the OTA and mount on the tripod. Fine enough, fast enough, for many occultations. It meant that settings 1 through 3 were about 1/30th, 1/15th, and 1/7th of a second. It confirmed that the integration setting 9, of 256 frames, was 8.5 seconds. I learned that each frame represents 1/30th of a second. I finally figured out StellaCam integration settings! Damn! At long last. Put the poles for the light blind outside.

Remembered, for a change, to put a portable weather station outside. I put the tripod a little bit closer to house to afford a bit more room around the south end of the porch. It put the 'scope down on the deck floor, out of the Sun, to cool. The telescope, mount, and tripod were outside.
