On Wednesday, Sunspot AR3848 sent a powerful solar flare directly toward earth. Based on the intensity and length of the coronal mass ejections (CME), NOAA and NASA forecasted that it could cause a severe G-4 class geomagnetic storm, with the possibility of auroras being visible further south than usual. The CME arrived on Thursday generating multiple alerts.
I went outside a little after 7 PM to possibly set up a camera to capture the Northern Lights. I don’t have a good view of the horizon to the north and hoped to see something above the trees. I wasn’t expecting anything this early as it was just dark out. To my amazement the sky looking north was bright red, and when I looked to the east and then south saw the typical aurora green. The display was everywhere, even straight up. It was much brighter than I expected, easily visible to the eye, not just with a digital camera. I wasn’t sure which direction to point the camera. I ended up setting up several cameras with wide angle lenses pointing different directions, including one with a fisheye lens with a 180° view pointing straight up. Each camera was set to take images every 30 seconds (30 second exposure, f/8, ISO 1600). Even though I missed some of the initial brightest display, I left the cameras out for several more hours. They did come back several times. I used the images to create the following time lapse videos.

With the sky clear, I set up the Vespera Observation station with a solar filter during the day to observe sunspots. When I reviewed the images, I found one with a silhouette of a bird (Turkey Vulture?) flying in front of the sun. In the past I have capture images of planes, and sometimes satellites transiting the solar disk. While on Semester at Sea voyages, we had an informal contest to capture images of ships at the horizon passing in front of the sun at sunset (or sunrise).

Once it got dark out, I set up both the Vespera and Stellina observation stations to observe deep sky objects (galaxies, nebulae, star clusters). The Vespera was fitted with a dual band (H-alpha and O-III) filter. The Vespera captured images of NGC 6960: Western Veil Nebula, Witch’s Broom Nebula; IC 1396: Elephant’s Trunk Nebula; and IC 1795: Fish Head Nebula. The final one didn’t go to completion due to condensation on the lens.

For the Stellina, I used the “Plan My Night” option to collect images of Messier 29 Open Cluster (M29, NGC 6913); NGC 6946 (Fireworks Galaxy); NGC 7331 Spiral Galaxy (Caldwel 30); Messier 31 Spiral Galaxy (Andromeda Galaxy, NGC 224); Messier 74 Spiral Galaxy (M74, NGC 628, Phantom Galaxy); Messier 110 Dwarf Elliptical Galaxy (M10, NGC 205); IC 342: The Hidden Galaxy in Camelopardalis. The system was set to collect images for about an hour for each object. For some reason, the telescope did not automatically close at the end of the collection. I am not sure if the external Anker Power USB power supply ran out. The lens was covered with dew. The Stellina system has a lens heater that is supposed to prevent condensation so may be the reason the power bank ran out. The Vespera system does not have the lens heater option installed.

As a really cold mass of air moved in the night sky was very clear. Lots of stars visible even though the moon was nearly full. I moved both the Stellina and Vespera telescope/cameras to the back patio and allowed them to equilibrate to the cold temperature (14°F/-10°C). Both systems needed to have their software/firmware upgraded before being initialized. They were then programmed to collect images of Comet C/2022 E3 (ZTF). It appears that the boxier Stellina is more sensitive to wobbling in the wind. The system only accepted 33-50% of the images and even then there was some doubling/streaking of the stars. The Vespera with its curved surfaces is more aerodynamic and did not appear to be impacted by the wind. The software/firmware update improved the quality of the exported composite TIF images. Time-lapse videos were generated from the JPG images showing the movement of the comet relative to the stars. The battery for the Vespera gave up after about 5 hours, even though an external battery was attached due to the extreme cold. The Stellina does not have an internal battery. The external battery lasted a bit longer, allowing me to create a time-lapse video of the moon. You can definitely see when the wind was blowing resulting in some distorted moon images.

I just arrived back home from a short trip to Florida and the night sky was clear. Comet C/2022 E3 (ZTF) is now visible in the early evening sky. Both the Stellina and Vespera telescope/cameras were used to capture images. The telescopes automatically track the motion of the stars in the sky while taking 10 second images. During the time of the observations (15-63 minutes), the comet is moving, creating a tail in the image. This motion can be viewed in the time-lapse video.

After two days of cloudy skies, the sky cleared just long enough before dawn to capture images of Comet C/2022 E3 (ZTF). This time with both the Stellina and Vespera telescope/cameras. The comet is high enough above the horizon to the north-east before dawn to be viewed above my house from my patio. I use the Sky Live website to get the location of the comet, and then enter the numbers into the Singularity application. Within minutes, both the Stellina and Vespera had the comet centered and start taking images.
