We report a large-scale coronal wave (so-called “EIT wave”) observed with high cadence by EUVI onboard STEREO in association with the GOES B9.5 flare and double CME event on 19 May 2007. The EUVI instruments provide us with the unprecedented opportunity to study the dynamics of flare/CME associated coronal waves. The coronal wave under study reveals deceleration, indicative of a freely propagat...

An interappointment flare-up is an unhappy event. After a root canal treatment appointment, the patient calls or returns to the dentist’s office in distress. This is upsetting to both the patient and the dentist and is disruptive to a busy practice. It would be desirable to understand the phenomenona to know how to prevent the occurrence and be able to manage this event. However, the flare-up p...

Context. Recently, the MAGIC collaboration reported evidence for a delay in the arrival times of photons of different energies during a γ-ray flare from the blazar Markarian 501 on 2005 July 9. Aims. We aim at describing the observed delayed high-energy emission. Methods. We apply a homogeneous synchrotron self-Compton (SSC) model under the assumption that the blob containing relativistic elect...

We present the light curve of the little studied flare star AF Psc (M4.5V) obtained using engineering data from the K2 mission. Data were obtained in Long Cadence mode giving an effective exposure of 29 min and nearly 9 d of coverage. A clear modulation on a period of 1.08 d was seen which is the signature of the stellar rotation period. We identify 14 flares in the light curve, with the most l...

The treatment of systemic lupus erythematosus (SLE) nephritis, while effective, is associated with significant morbidity and mortality. These side effects could be mitigated if the onset, severity, and response of renal flare could be predicted, and therapy modified accordingly. In this review, an approach to derive prediction equations of SLE nephritis flare is discussed. Integral to generatin...
